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 Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
