4af34177b6 Monahans: avoid floating point calculations
Current code for the Monahans CPU defined OSCR_CLK_FREQ as 3.250 (MHz)
which caused floating point operations to be used. This resulted in
unresolved references to some FP related libgcc functions when using
U-Boot's private libgcc functions.

Change the code to use fixed point math only.

cfa460adfd Update MTD to that of Linux 2.6.22.1
A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.

This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.

MAKEALL ppc/arm has some issues:
 * DOC/OneNand/nand_spl is not building (I have not tried porting
   these parts, and since I do not have any HW and I am not familiar
   with this code/HW I think its best left to someone else.)

Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
 cpu/ppc4xx/ndfc.c
 cpu/arm926ejs/davinci/nand.c
 board/delta/nand.c
 board/zylonite/nand.c

5e378003d5 board/[Ma-i]*: Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).
This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

f9e029184b 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.

bf7cac033b 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.

e2053f9c7a 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.
