+altera-cyclone-v (Intel Cyclone V)
+==================================
+
+This BSP offers only one variant, the `altcycv_devkit`. This variant supports
+the Intel Cyclone V system on chip. The basic hardware initialization is not
+performed by the BSP. A boot loader with device tree support must be used to
+start the BSP, e.g. U-Boot.
+
+The BSP is known to run on these boards:
+
+* `Cyclone V SoC Development Kit <https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/kit-cyclone-v-soc.html>`_
+
+* `Enclustra Mars MA3 SoC Module <https://www.enclustra.com/en/products/system-on-chip-modules/mars-ma3/>`_
+
+* `Terasic DE10-Standard Development Kit <https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=165&No=1081>`_
+
+Boot via U-Boot
+---------------
+
+The application executable file (ELF file) must be converted to an U-Boot
+image. Use the following commands:
+
+.. code-block:: none
+
+ arm-rtems5-objcopy -O binary app.exe app.bin
+ gzip -9 -f -c app.bin > app.bin.gz
+ mkimage -A arm -O linux -T kernel -a 0x00300000 -e 0x00300000 -n RTEMS -d app.bin.gz app.img
+
+Use the following U-Boot commands to boot an application via TFTP download:
+
+.. code-block:: none
+
+ tftpboot ${loadaddr} app.img && run loadfdt && bootm ${loadaddr} - ${fdt_addr} ; reset
+
+The ``loadfdt`` command may be not defined in your U-Boot environment. Just
+replace it with the appropriate commands to load the device tree at
+``${fdt_addr}``.
+
+Clock Driver
+------------
+
+The clock driver uses the `Cortex-A9 MPCore Global Timer`.
+
+Console Driver
+--------------
+
+The console driver supports up to two on-chip NS16550 UARTs. The console
+driver does not configure the pins.
+
+I2C Driver
+----------
+
+There is a legacy I2C driver. It should be converted to the I2C driver framework.
+
+Network Interface Driver
+------------------------
+
+The network interface driver is provided by the `libbsd`. It is initialized
+according to the device tree. It supports checksum offload.
+
+MMC/SDCard Driver
+-----------------
+
+The MMC/SDCard driver is provided by the `libbsd`. It is
+initialized according to the device tree. Pin re-configuration according to
+the serial clock frequency is not supported. DMA transfers are supported.
+
+USB Host Driver
+---------------
+
+The USB host driver is provided by the `libbsd`. It is initialized according
+to the device tree. The driver works in polled mode.
+
+Caveats
+-------
+
+The clock and pin configuration support is quite rudimentary and mostly relies
+on the boot loader.

+imx (NXP i.MX)
+==============
+
+This BSP offers only one variant, the `imx7`. This variant supports the i.MX
+7Dual processor. The basic hardware initialization is not performed by the
+BSP. A boot loader with device tree support must be used to start the BSP,
+e.g. U-Boot.
+
+Build Configuration Options
+---------------------------
+
+The following options are available at the configure command line.
+
+``BSP_PRESS_KEY_FOR_RESET``
+ If defined to a non-zero value, then print a message and wait until pressed
+ before resetting board when application terminates.
+
+``BSP_RESET_BOARD_AT_EXIT``
+ If defined to a non-zero value, then reset the board when the application
+ terminates.
+
+``BSP_PRINT_EXCEPTION_CONTEXT``
+ If defined to a non-zero value, then print the exception context when an
+ unexpected exception occurs.
+
+``BSP_FDT_BLOB_SIZE_MAX``
+ The maximum size of the device tree blob in bytes (default is 262144).
+
+``CONSOLE_USE_INTERRUPTS``
+ Use interrupt driven mode for console devices (enabled by default).
+
+``IMX_CCM_IPG_HZ``
+ The IPG clock frequency in Hz (default is 67500000).
+
+``IMX_CCM_UART_HZ``
+ The UART clock frequency in Hz (default is 24000000).
+
+``IMX_CCM_AHB_HZ``
+ The AHB clock frequency in Hz (default is 135000000).
+
+Boot via U-Boot
+---------------
+
+The application executable file (ELF file) must be converted to an U-Boot
+image. Use the following commands:
+
+.. code-block:: none
+
+ arm-rtems5-objcopy -O binary app.exe app.bin
+ gzip -9 -f -c app.bin > app.bin.gz
+ mkimage -A arm -O linux -T kernel -a 0x80200000 -e 0x80200000 -n RTEMS -d app.bin.gz app.img
+
+Use the following U-Boot commands to boot an application via TFTP download:
+
+.. code-block:: none
+
+ tftpboot ${loadaddr} app.img && run loadfdt && bootm ${loadaddr} - ${fdt_addr} ; reset
+
+The ``loadfdt`` command may be not defined in your U-Boot environment. Just
+replace it with the appropriate commands to load the device tree at
+``${fdt_addr}``.
+
+Clock Driver
+------------
+
+The clock driver uses the `ARMv7-AR Generic Timer`.
+
+Console Driver
+--------------
+
+The console driver supports up to seven on-chip UARTs. They are initialized
+according to the device tree. The console driver does not configure the pins.
+
+I2C Driver
+----------
+
+I2C drivers are registered by the ``i2c_bus_register_imx()`` function. The I2C
+driver does not configure the pins.
+
+.. code-block:: c
+
+ #include <assert.h>
+ #include <bsp.h>
+
+ void i2c_init(void)
+ {
+ int rv;
+
+ rv = i2c_bus_register_imx("/dev/i2c-0", "i2c0");
+ assert(rv == 0);
+ }
+
+SPI Driver
+----------
+
+SPI drivers are registered by the ``spi_bus_register_imx()`` function. The SPI
+driver configures the pins according to the ``pinctrl-0`` device tree property.
+SPI transfers with a continuous chip select are limited by the FIFO size of 64
+bytes. The driver has no DMA support.
+
+.. code-block:: c
+
+ #include <assert.h>
+ #include <bsp.h>
+
+ void spi_init(void)
+ {
+ int rv;
+
+ rv = spi_bus_register_imx("/dev/spi-0", "spi0");
+ assert(rv == 0);
+ }
+
+Network Interface Driver
+------------------------
+
+The network interface driver is provided by the `libbsd`. It is initialized
+according to the device tree. It supports checksum offload and interrupt
+coalescing. IPv6 transmit checksum offload is not implemented. The interrupt
+coalescing uses the MII/GMII clocks and can be controlled by the following
+system controls:
+
+ * ``dev.ffec.<unit>.int_coal.rx_time``
+ * ``dev.ffec.<unit>.int_coal.rx_count``
+ * ``dev.ffec.<unit>.int_coal.tx_time``
+ * ``dev.ffec.<unit>.int_coal.tx_count``
+
+A value of zero for the time or count disables the interrupt coalescing in the
+corresponding direction.
+
+MMC/SDCard Driver
+-----------------
+
+The MMC/SDCard driver (uSDHC module) is provided by the `libbsd`. It is
+initialized according to the device tree. Pin re-configuration according to
+the serial clock frequency is not supported. Data transfers are extremely
+slow. This is probably due to the missing DMA support.
+
+Caveats
+-------
+
+The clock and pin configuration support is quite rudimentary and mostly relies
+on the boot loader. For a pin group configuration see
+``imx_iomux_configure_pins()``. There is no power management support.

+lpc24xx (NXP LPC17XX/LPC24XX/LPC40XX)
+=====================================
+
+This BSP offers only several variants. The following variants support the
+`Embedded Artits LPC4088 Developer's Kit <https://www.embeddedartists.com/products/lpc4088-developers-kit/>`_
+and earlier board generations:
+
+* lpc17xx_ea_ram
+
+* lpc17xx_ea_rom_int
+
+* lpc24xx_ea
+
+* lpc40xx_ea_ram
+
+* lpc40xx_ea_rom_int
+
+They can be used as a base line for customization. The basic hardware
+initialization is performed by the BSP. It can be customized via configuration
+options and configuration tables. See also
+`<bsp/start-config.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/start-config.h>`_.
+
+Clock Driver
+------------
+
+The clock driver of the Cortex-M variants uses the `ARMv7-M Systick`. The
+older ARM7TDMI variants use the `TMR0` timer module.
+
+Console Driver
+--------------
+
+The console driver supports up to four on-chip UARTs. Initialization can be
+customized via the ``lpc24xx_uart_probe_1()``, ``lpc24xx_uart_probe_2()`` and
+``lpc24xx_uart_probe_3()`` functions.
+
+I2C Bus Driver
+--------------
+
+I2C bus drivers are registered by the ``lpc24xx_register_i2c_0()``,
+``lpc24xx_register_i2c_1()`` and ``lpc24xx_register_i2c_2()`` functions. The
+I2C driver does not configure the pins. See also
+`<bsp/i2c.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/i2c.h>`_.
+
+SPI Bus Driver
+--------------
+
+SPI bus drivers are registered by the ``lpc24xx_register_ssp_0()``,
+``lpc24xx_register_ssp_1()`` and ``lpc24xx_register_ssp_2()`` functions. The
+SSP driver does not configure the pins. See also
+`<bsp/ssp.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/ssp.h>`_.
+
+Network Interface Driver
+------------------------
+
+Only a legacy network driver is support. For a `libbsd` base driver the
+platform support is missing, see
+`if_lpe.c <https://git.rtems.org/rtems-libbsd/tree/rtemsbsd/sys/arm/lpc/if_lpe.c>`_.
+
+USB Driver
+----------
+
+The USB host driver (OHCI) is provided by the `libbsd`.
+
+Framebuffer Driver
+------------------
+
+For a custom framebuffer driver see
+`<bsp/lcd.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/lcd.h>`_.
+
+RTC Driver
+----------
+
+There is a standard RTC driver available using the on-chip RTC module.

-imx (NXP i.MX)
-==============
-
-This BSP offers only one variant, the `imx7`. This variant supports the i.MX
-7Dual processor. The basic hardware initialization is not performed by the
-BSP. A boot loader with device tree support must be used to start the BSP,
-e.g. U-Boot.
-
-Build Configuration Options
----------------------------
-
-The following options are available at the configure command line.
-
-``BSP_PRESS_KEY_FOR_RESET``
- If defined to a non-zero value, then print a message and wait until pressed
- before resetting board when application terminates.
-
-``BSP_RESET_BOARD_AT_EXIT``
- If defined to a non-zero value, then reset the board when the application
- terminates.
-
-``BSP_PRINT_EXCEPTION_CONTEXT``
- If defined to a non-zero value, then print the exception context when an
- unexpected exception occurs.
-
-``BSP_FDT_BLOB_SIZE_MAX``
- The maximum size of the device tree blob in bytes (default is 262144).
-
-``CONSOLE_USE_INTERRUPTS``
- Use interrupt driven mode for console devices (enabled by default).
-
-``IMX_CCM_IPG_HZ``
- The IPG clock frequency in Hz (default is 67500000).
-
-``IMX_CCM_UART_HZ``
- The UART clock frequency in Hz (default is 24000000).
-
-``IMX_CCM_AHB_HZ``
- The AHB clock frequency in Hz (default is 135000000).
-
-Boot via U-Boot
----------------
-
-The application executable file (ELF file) must be converted to an U-Boot
-image. Use the following commands:
-
-.. code-block:: none
-
- arm-rtems5-objcopy -O binary app.exe app.bin
- gzip -9 -f -c app.bin > app.bin.gz
- mkimage -A arm -O linux -T kernel -a 0x80200000 -e 0x80200000 -n RTEMS -d app.bin.gz app.img
-
-Use the following U-Boot commands to boot an application via TFTP download:
-
-.. code-block:: none
-
- tftpboot ${loadaddr} app.img && run loadfdt && bootm ${loadaddr} - ${fdt_addr} ; reset
-
-The ``loadfdt`` command may be not defined in your U-Boot environment. Just
-replace it with the appropriate commands to load the device tree at
-``${fdt_addr}``.
-
-Clock Driver
-------------
-
-The clock driver uses the `ARMv7-AR Generic Timer`.
-
-Console Driver
---------------
-
-The console driver supports up to seven on-chip UARTs. They are initialized
-according to the device tree. The console driver does not configure the pins.
-
-I2C Driver
-----------
-
-I2C drivers are registered by the ``i2c_bus_register_imx()`` function. The I2C
-driver does not configure the pins.
-
-.. code-block:: c
-
- #include <assert.h>
- #include <bsp.h>
-
- void i2c_init(void)
- {
- int rv;
-
- rv = i2c_bus_register_imx("/dev/i2c-0", "i2c0");
- assert(rv == 0);
- }
-
-SPI Driver
-----------
-
-SPI drivers are registered by the ``spi_bus_register_imx()`` function. The SPI
-driver configures the pins according to the ``pinctrl-0`` device tree property.
-SPI transfers with a continuous chip select are limited by the FIFO size of 64
-bytes. The driver has no DMA support.
-
-.. code-block:: c
-
- #include <assert.h>
- #include <bsp.h>
-
- void spi_init(void)
- {
- int rv;
-
- rv = spi_bus_register_imx("/dev/spi-0", "spi0");
- assert(rv == 0);
- }
-
-Network Interface Driver
-------------------------
-
-The network interface driver is provided by the `libbsd`. It is initialized
-according to the device tree. It supports checksum offload and interrupt
-coalescing. IPv6 transmit checksum offload is not implemented. The interrupt
-coalescing uses the MII/GMII clocks and can be controlled by the following
-system controls:
-
- * ``dev.ffec.<unit>.int_coal.rx_time``
- * ``dev.ffec.<unit>.int_coal.rx_count``
- * ``dev.ffec.<unit>.int_coal.tx_time``
- * ``dev.ffec.<unit>.int_coal.tx_count``
-
-A value of zero for the time or count disables the interrupt coalescing in the
-corresponding direction.
-
-MMC/SDCard Driver
------------------
-
-The MMC/SDCard driver (uSDHC module) is provided by the `libbsd`. It is
-initialized according to the device tree. Pin re-configuration according to
-the serial clock frequency is not supported. Data transfers are extremely
-slow. This is probably due to the missing DMA support.
-
-Caveats
--------
-
-The clock and pin configuration support is quite rudimentary and mostly relies
-on the boot loader. For a pin group configuration see
-``imx_iomux_configure_pins()``. There is no power management support.

-lpc24xx (NXP LPC17XX/LPC24XX/LPC40XX)
-=====================================
-
-This BSP offers only several variants. The following variants support the
-`Embedded Artits LPC4088 Developer's Kit <https://www.embeddedartists.com/products/lpc4088-developers-kit/>`_
-and earlier board generations:
-
-* lpc17xx_ea_ram
-
-* lpc17xx_ea_rom_int
-
-* lpc24xx_ea
-
-* lpc40xx_ea_ram
-
-* lpc40xx_ea_rom_int
-
-They can be used as a base line for customization. The basic hardware
-initialization is performed by the BSP. It can be customized via configuration
-options and configuration tables. See also
-`<bsp/start-config.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/start-config.h>`_.
-
-Clock Driver
-------------
-
-The clock driver of the Cortex-M variants uses the `ARMv7-M Systick`. The
-older ARM7TDMI variants use the `TMR0` timer module.
-
-Console Driver
---------------
-
-The console driver supports up to four on-chip UARTs. Initialization can be
-customized via the ``lpc24xx_uart_probe_1()``, ``lpc24xx_uart_probe_2()`` and
-``lpc24xx_uart_probe_3()`` functions.
-
-I2C Bus Driver
---------------
-
-I2C bus drivers are registered by the ``lpc24xx_register_i2c_0()``,
-``lpc24xx_register_i2c_1()`` and ``lpc24xx_register_i2c_2()`` functions. The
-I2C driver does not configure the pins. See also
-`<bsp/i2c.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/i2c.h>`_.
-
-SPI Bus Driver
---------------
-
-SPI bus drivers are registered by the ``lpc24xx_register_ssp_0()``,
-``lpc24xx_register_ssp_1()`` and ``lpc24xx_register_ssp_2()`` functions. The
-SSP driver does not configure the pins. See also
-`<bsp/ssp.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/ssp.h>`_.
-
-Network Interface Driver
-------------------------
-
-Only a legacy network driver is support. For a `libbsd` base driver the
-platform support is missing, see
-`if_lpe.c <https://git.rtems.org/rtems-libbsd/tree/rtemsbsd/sys/arm/lpc/if_lpe.c>`_.
-
-USB Driver
-----------
-
-The USB host driver (OHCI) is provided by the `libbsd`.
-
-Framebuffer Driver
-------------------
-
-For a custom framebuffer driver see
-`<bsp/lcd.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/lcd.h>`_.
-
