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".

* 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.

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.
