-NOTES
-=====
-
-This BSP is based on the gen68302. The main differences are C code for
-boot parameters, the gdb monitor, and variant support.
-
-The boot code which changes is written in C and the parameters used to
-control the configuration of the chip select registers and parallel
-ports are held in variant specific header files. These file also
-control the other hardware specific definitions such the processor
-freqency.
-
-The gdb monitor currently uses two serial ports. One for the debugger
-and one for stdio. This is costly in terms of the 68302 processor.
-
-The build configuration contains the memory map. The bsp code does not
-contain any memory map parameters. That is the ods68302.cfg contains
-the link addresses.
-
-To build a version to download via gdb use the command line parameters
-to make or "RTEMS_DEBUGGER=yes". This will change the memory map to
-place the code, and data above the RAM used by the gdb stub.
-
-TODO
-====
-
-1) Lower the set size of the gdb monitor. This can be made to be about
-10K or RAM. The code is about 14K.
-
-2) Add the production memory test code. This will be C and asm
-code. The asm will be a faster version of the C.

- Card Definition for a bare board.
-
- This is an example file which actually builds a BSP for a 68302 card
- called an MVF (Multi-Voice-Frequency). The card is one of a range
- which run in a 100Mbit voice/video/data switch used for high end
- applications such as Air Traffic Control. The transport is
- FDDI-2. Yes it alive and well and working in real systems.
-
- Chip selects are programmed as required. Three are controlled in the
- boot code. They are RAM, ROM, and peripherals. You can optionally
- configure the other two chip selects.
-
- SYSTEM_CLOCK - You must defined this. It is used for setting the
- baud rate.
-
- CSEL_ROM, CSEL_RAM - Must be defined, and made to be a single number
- with brackets.
-
- ROM_WAIT_STATES, RAM_WAIT_STATES - Must be defined. This sets the
- speed for the ROM and RAM.
-
- ROM and RAM size is passed on the command line. The makefile holds
- them. This allows a single place to defined it. The makefile allows
- them to be passed to the linker.
-
- CSEL_1, CSEL_2 - If defined the other macros needed to define the
- chip select must be defined. If not defined they are not programmed
- and registers are left in the reset state.
-
- Card Specific Devices - The MVF card uses a chip select to address a
- range of peripherials (CSEL_2). These include front panel leds, and
- 4 digit diagnostic display device. Put what ever you need.
-
- LED_CONTROL - If defined the boot code will set leds as it goes.
-
- UPDATE_DISPLAY - A four digit display device will also be updated to
- show the boot state.
-
- CARD_PA, CARD_PB - The default configuration, data direction and
- data must be specified.
-
- This file allows a range of common parameters which vary from one
- variant of card to another to placed in a central file.

- Boot the CPU.
-
- Occurs in 3 phases for a 68302.
-
- Phase 1.
-
- Called as soon as able after reset. The BAR has been programed, and
- a small stack exists in the DPRAM. All interrupts are masked, and
- the processor is running in supervisor mode. No other hardware or
- chip selects are active.
-
- This phase programs the chip select registers, the parallel ports
- are set into default configurations, and basic registers cleared or
- reset. The leds are programmed to show the end of phase 1.
-
- Phase 2.
-
- This is a piece of code which is copied to DPRAM and executed. It
- should not do any more thann is currently present. The return to ROM
- is managed by modifing the return address. Again leds show the status.
-
- Phase 3.
-
- This code executes with a valid C environment. That is the data
- section has been intialised and the bss section set to 0. This phase
- performs any special card initialisation and then calls boot card.

- * To enable debugger support, two things need to happen. One, a
- * call to set_debug_traps() is necessary in order to allow any breakpoints
- * or error conditions to be properly intercepted and reported to gdb.
- * Two, a breakpoint needs to be generated to begin communication. This
- * is most easily accomplished by a call to breakpoint(). Breakpoint()
- * simulates a breakpoint by executing a trap #1. The breakpoint instruction
- * is hardwired to trap #1 because not to do so is a compatibility problem--
- * there either should be a standard breakpoint instruction, or the protocol
- * should be extended to provide some means to communicate which breakpoint
- * instruction is in use (or have the stub insert the breakpoint).
- *
- * Some explanation is probably necessary to explain how exceptions are
- * handled. When an exception is encountered the 68000 pushes the current
- * program counter and status register onto the supervisor stack and then
- * transfers execution to a location specified in it's vector table.
- * The handlers for the exception vectors are hardwired to jmp to an address
- * given by the relation: (exception - 256) * 6. These are decending
- * addresses starting from -6, -12, -18, ... By allowing 6 bytes for
- * each entry, a jsr, jmp, bsr, ... can be used to enter the exception
- * handler. Using a jsr to handle an exception has an added benefit of
- * allowing a single handler to service several exceptions and use the
- * return address as the key differentiation. The vector number can be
- * computed from the return address by [ exception = (addr + 1530) / 6 ].
- * The sole purpose of the routine _catchException is to compute the
- * exception number and push it on the stack in place of the return address.
- * The external function exceptionHandler() is
- * used to attach a specific handler to a specific m68k exception.
- * For 68020 machines, the ability to have a return address around just
- * so the vector can be determined is not necessary because the '020 pushes an
- * extra word onto the stack containing the vector offset
- *
- * Because gdb will sometimes write to the stack area to execute function
- * calls, this program cannot rely on using the supervisor stack so it
- * uses it's own stack area reserved in the int array remcomStack.
- *
- *************
- *
- * The following gdb commands are supported:
- *
- * command function Return value
- *
- * g return the value of the CPU registers hex data or ENN
- * G set the value of the CPU registers OK or ENN
- *
- * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
- * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
- *
- * c Resume at current address SNN ( signal NN)
- * cAA..AA Continue at address AA..AA SNN
- *
- * s Step one instruction SNN
- * sAA..AA Step one instruction from AA..AA SNN
- *
- * k kill
- *
- * ? What was the last sigval ? SNN (signal NN)
- *
- * All commands and responses are sent with a packet which includes a
- * checksum. A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer. '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host: Reply:
- * $m0,10#2a +$00010203040506070809101112131415#42
