CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

This patch fixes some problems for the T3CORP board. Here the list
of the changes:
- Add 600-67 and 677 CPU frequency setting to chip_config
command
- Define CONFIG_DDR_RFDC_FIXED on t3corp:
While using the "normal" auto calibration code, sometimes values for
RFDC were picked (>= T3) that resulted in a non-working U-Boot (hang
upon relocation, while running from SDRAM). With this optimized RFDC
value we can force this register and use the auto-calibration code to
setup the remaining calibration registers.
- Increase sizes of FPGA chips selects
- EBC timing updated OEN=3 for 66 MHz EBC speed
- Change ext. IRQ2 setup to level-low active
- Enable CONFIG_SYS_CFI_FLASH_STATUS_POLL
By defining CONFIG_SYS_CFI_FLASH_STATUS_POLL, DQ7 is polled to detect the
chip busy status. This is now used instead of the data toggle method which
is used historically by default in the common CFI driver. With this change
a problem with not written data is solved on this board, where a 32 byte
block of data is still erased instead of filled with the correct content
after these commands:
=> erase 0xfc100000 +0x1000000
....................................................................
done
Erased 128 sectors
=> cp.b 0x100000 0xfc100000 0x1000000
Copy to Flash... done
=> cmp.b 0x100000 0xfc100000 0x1000000
byte at 0x00d0d6c0 (0x00) != byte at 0xfcd0d6c0 (0xff)
Total of 12637888 bytes were the same

This patch adds new macros, with frequently used combinations of the
4xx TLB access control and storage attibutes. Additionally the 4xx init.S
files are updated to make use of these new macros. Resulting in easier
to read TLB definitions.
Additionally some init.S files are updated to use the mmu header for the
TLB defines, instead of defining their own macros.

The appropriate include/asm-$ARCH directory should already by symlinked
to include/asm so using the whole "asm-$ARCH" path is unnecessary.
This change should also allow us to move the include/asm-$ARCH
directories into their appropriate lib/$ARCH/ directories.

The AMCC Luan now uses the common 440SP(e) DDR SPD code for DDR
inititializition. This includes DDR auto calibration and support
for different DIMM modules, instead of the fixed setup used in
the earlier version.
This patch also enables the cache in FLASH for the startup
phase of U-Boot (while running from FLASH). After relocating to
SDRAM the cache is disabled again. This will speed up the boot
process, especially the SDRAM setup, since there are some loops
for memory testing (auto calibration).

- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
