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.

There were several, now there is one (two if you count the lower-case
versions).

- Fixing leading white spaces
- Fixing indentation where 4 spaces are used instead of tab
- Removing C++ comments (//), wherever I introduced them

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

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)

Some more NAND cleanup and small fixes.

* 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.
|
|
* 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.

don't ask me why. There are still bugs in the bad block logic.
|
|
after all.
|
|
start at an offset of 4 bytes from the start of the page.
|
|
|
|
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.
