Remove legacy NAND and disk on chip code.

2009-07-17T00:07:47+00:00

Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

mtd: nand: use loff_t for offset

2009-07-07T22:58:06+00:00

nand_util currently uses size_t which is arch dependent and not always a
unsigned long.  Now use loff_t, as does the linux mtd layer.

NAND: move board_nand_init to nand.h

2009-01-23T16:32:49+00:00

Rather than putting the function prototype for board_nand_init() in the one
place where it gets called, put it into nand.h so that every place that also
defines it gets the prototype.  Otherwise, errors can go silently unnoticed
such as using the wrong return value (void rather than int) when defining
the function.

NAND boot: MPC8313ERDB support

2008-08-12T16:31:31+00:00

Note that with older board revisions, NAND boot may only work after a
power-on reset, and not after a warm reset.  I don't have a newer board
to test on; if you have a board with a 33MHz crystal, please let me know
if it works after a warm reset.

Update MTD to that of Linux 2.6.22.1

2008-08-12T16:31:15+00:00

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

NAND: ifdef-protect most of nand.h when using legacy NAND.

2008-07-09T22:47:52+00:00

Some macros such as NAND_CTL_SETALE conflict between current and legacy
NAND, being defined by the subsystem in the former case and the board
config file in the latter.
