Add Virtex4 and Virtex5 BSPs
This commit covers at least PR2020, 2022, and 2023. This
patch adds all of the code for both BSPs, modifications
to libcpu/powerpc for the ppc440, and some updates to the
BSPs from follow up review and testing.
These BSPs should be good baselines for future development.
The configurations used by Ric are custom and have a non-standard
NIC. They also do not have a UART. Thus the current console
driver just prints to a RAM buffer.
The NIC and UART support are left for future work. When the UART
support is added, moving the existing "to RAM" console driver to
a shared location is likely desirable because boards with no debug
UART port are commonly deployed. This would let printk() go to RAM.

+ * Updated for a 25MHz Papyrus by Andrew Bray <andy at i-cubed.co.uk>
+ *
+ * Units are 100ns.
+ *
+ * These numbers are of questionable use, as they are developed by calling
+ * the routine many times, thus getting its entry veneer into the (small)
+ * cache on the 403GA. This in general is not true of the RTEMS timing
+ * tests, which usually call a routine only once, thus having no cache loaded
+ * advantage.
+ *
+ * Whether the directive times are useful after deducting the function call
+ * overhead is also questionable. The user is more interested generally
+ * in the total cost of a directive, not the cost if the procedure call
+ * is inlined! (In general this is not true).

+* @brief Initialization code to set up the CPU and call boot_card()
+*
+* This "BSP" targets the Xilinx Virtex XC4VFX60 and related parts. This
+* BSP makes no assumptions on what firmware is loaded into the FPGA.
+*
+* Provides the .entry section code. This is the first code to run in
+* the PPC after download to RAM. Excecution in this case starts at
+* 'download_entry'.
+*
+* The entrypoint 'start' is provided for the case where a bootloader has
+* initialized the CPU, and all that remains to do is to set up a C
+* environment and call boot_card.
+*
+* Derived from virtex dlentry and others.
+*
+* IBM refers to the version of the processor as PPC405F5.
+* The processor version register returns 0x20011470.

+/*!@file start.S
+*
+* @brief Initialization code to set up the CPU and call boot_card()
+*
+* This "BSP" targets the Xilinx Virtex XC5VFX70T and related parts. This
+* BSP makes no assumptions on what firmware is loaded into the FPGA.
+*
+* Provides the .entry section code. This is the first code to run in
+* the PPC after download to RAM. Excecution in this case starts at
+* 'download_entry'.
+*
+* The entrypoint 'start' is provided for the case where a bootloader has
+* initialized the CPU, and all that remains to do is to set up a C
+* environment and call boot_card.
+*
+* Derived from virtex dlentry and others.
+*
+* Some portions of this code follow section 3.4 of the PPC440x5 CPU Core User's
+* Manual v7.1 from IBM. Other parts were derived from examples provided
+* by Xilinx in their ML510 Reference Designs, e.g., ml510_bsb1_design_ppc440.
+* See boot.S in standalone/, for example.
