NAND finally working. Two bugs fixed:
* For READ_STATUS and READID commands always 8 bytes need to be read from
NDDB. Otherwise they stay there and get send to flash as the first data
word when writing.
* In nand_base.c the oob variable is not reset so this->oob_buf is
overwritten what eventually screws up the bad block descriptor table.

Merge the new NAND code (testing-NAND brach); see doc/README.nand
Rewrite of NAND code based on what is in 2.6.12 Linux kernel
Patch by Ladislav Michl, 29 Jun 2005
Re-factoring the legacy NAND code (legacy NAND now only in board-specific
code and in SoC code). Boards using the old way have CFG_NAND_LEGACY and
BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
implemented for these boards.
Lots of new stuff:
* Debug message can be turned on and off.
* Waiting for events now times out.
* Implemented RESET command.
* Added appropriate nand_bbt_descriptor and nand_oobinfo.
Remaining Problems:
* Read Status still behaves weird an returns invalid stuff sometimes.
* ECC Placement does not respect our scheme in nand_oobinfo.
Moved the waiting loop for "Read Data Request" RDDREQ into the
delta_cmdfunc function, because this bit is only set once after a command
is sent and this allows read functions to be called multiple times.

Major CFI-FLASH driver update:
* Add env-variable "unlock" to handle initial state of sectors
(locked/unlocked).
Only the U-Boot image and it's environment is protected,
all other sectors are unprotected (unlocked) if flash
hardware protection is used (CFG_FLASH_PROTECTION) and
the environment variable "unlock" is set to "yes".

- find_sector() called in both versions of flash_write_cfiword()

* CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode
Patch by Jose Maria Lopez, 16 Jan 2006
* Add support for AMD/Spansion Flashes in flash_write_cfibuffer
Patch by Alex Bastos and Thomas Schaefer, 2005-08-29
* Changes/fixes for drivers/cfi_flash.c:
We *should* check if there are any error bits if the previous call
returned ERR_OK (Otherwise we will have output an error message in
flash_status_check() already.) The original code would only check for
error bits if flash_status_check() returns ERR_TIMEOUT.
Patch by Marcus Hall, 23 Aug 2005
* Changes/fixes for drivers/cfi_flash.c:
- Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c
- Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c
Patch by Sangmoon Kim, 19 Aug 2005
* Fixes for drivers/cfi_flash.c:
- Fix wrong timeout value usage in flash_status_check()
- Round write_tout up when converting to msec in flash_get_size()
- Remove clearing flash status at the end of flash_write_cfibuffer()
which sets Intel 28F640J3 flash back to command mode on CSB472

Add GIT version information (commid ID) to untagged U-Boot versions
As done in the linux kernel, the U-Boot version (U_BOOT_VERSION)
of all unreleased (untagged) U-Boot images will be automatically
extended upon compiletime with a part of the GIT commit ID and
possibly with "dirty" if uncommited changes are detected.
Here an example for the resulting version:
"U-Boot 1.1.4-g3457ac18-dirty"
The version is now maintained in the toplevel Makefile and the
version headers are autogenerated.
Reverting pxa-regs.h back to original, because the intel Monahans one
breaks backward compatibility and I don't trust it. Instead, i'll verify
and merge the parts I need while porting.
* lots of bugfixes in the assembler code
* reverted hardware.h back to original
* enabled hardware DRAM calibration
* GCC-4 fix: modified GLOBAL_DATA_POINTER macro
This is the first commit for the u-boot zylonite port. The following has be
done so far:
* created zylonite board dir (based on lubbock)
* extended some - but not all pxa sources and headers for Intel
Monahans support (CONFIG_CPU_MONAHANS)
* created Makefile zylonite target + MAKEALL entry
* added some debug nonsense, remove later, grep for mk@tbd
Status: compiles (eldk-4.0), and can be started with BDI, but runs forever
and doesn't halt at breakpoints. Hmmm...

Cleanup U-Boot boot messages on ARM.
To match the U-Boot user interface on ARM platforms to the U-Boot

Add support for TQM8541/8555 boards, TQM85xx support reworked:
- Support for TQM8541/8555 boards added.
- Complete rework of TQM8540/8560 support.
- Common TQM85xx code now supports all current TQM85xx platforms
(TQM8540/8541/8555/8560).
- DDR SDRAM size detection added.
- CAS latency default values can be overwritten by setting "serial#"
to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
If problems are detected with this non default CAS latency,
the defualt values will be used instead.
- FLASH size detection added.
- Moved FCC ethernet driver initialization behind TSEC driver init
-> TSEC is first device.

Changed PPC44x startup message (cpu info, speed...) to common style:
On PPC44x platforms, the startup message generated in "cpu.c" only
comprised the ppc type and revision but not additional informations
like speed etc. Those speed infos where printed in the board specific
code. This new implementation now prints all CPU infos in the common
cpu specific code. No board specific code is needed anymore and
therefore removed from all current 44x implementations.
