Rather than scanning on boot, scan upon the first attempt to check the
badness of a block. This speeds up boot when not using NAND, and reduces
the likelihood of needing to reflash via JTAG if NAND becomes
nonfunctional.

The hardware has separate registers for block and page-within-block,
but the division between the two has no apparent relation to the
actual erase block size of the NAND chip.

Using current driver elbc sometimes hangs during nand write. Reading back

This is a driver for the Flash Control Machine of the enhanched Local Bus
Controller found on some Freescale chips (such as the mpc8313 and the
mpc8379).
Signed-off-by: Scott Wood <scottwood@freescale.com>
Some hardware, such as the enhanced local bus controller used on some
mpc83xx chips, does ecc transparently when reading and writing data, rather
than providing a generic calculate/correct mechanism that can be exported to
the nand subsystem.
The subsystem should not BUG() when calculate, correct, or hwctl are
missing, if the methods that call them have been overridden.

This patch changes nand_wait_ready() to not just call nand_wait(),
since this will send a new command to the NAND chip. We just want to

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

FILL_15BIT_555RGB macro extension for pixel swapping
by commit bed53753dd
introduced a bug in cfb_console:
Bitmaps with odd-numbered width won't be rendered
correctly and even U-Boot crashes are observed on
some platforms while repeated rendering of such
bitmaps with "bmp display". Also if a bitmap is
rendered to an odd-numbered x starting position,
the same problem occurs. This patch is an attempt
to fix it.

The CFI driver allowed only for static initializers in the
CFG_FLASH_BANKS_LIST definition, i. e. it did not allow to map
several flash banks contiguously if the bank sizes were not known in
advance, which kind of violates U-Boot's design philosophy.
(will be used for example by the TQM8xxL boards)
