NOTE:
=====
We now use a complete rewrite of the NAND code based on what is in
2.6.12 Linux kernel.
The old NAND handling code has been re-factored and is now confined
to only board-specific files and - unfortunately - to the DoC code
(see below). A new configuration variable has been introduced:
CFG_NAND_LEGACY, which has to be defined in the board config file if
that board uses legacy code. If CFG_NAND_LEGACY is defined, the board
specific config.mk file should also have "BOARDLIBS =
drivers/nand_legacy/libnand_legacy.a". For boards using the new NAND
approach (PPChameleon and netstar at the moment) no variable is
necessary, but the config.mk should have "BOARDLIBS =
drivers/nand/libnand.a".
The necessary changes have been made to all affected boards, and no
build breakage has been introduced, except for NETTA and NETTA_ISDN
targets from MAKEALL. This is due to the fact that these two boards
use JFFS, which has been adopted to use the new NAND, and at the same
time use NAND in legacy mode. The breakage will disappear when the
board-specific code is changed to the new NAND.
As mentioned above, the legacy code is still used by the DoC subsystem.
The consequence of this is that the legacy NAND can't be removed from
the tree until the DoC is ported to use the new NAND support (or boards
with DoC will break).
