* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-0/+2
| | | | | | | | | 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. Signed-off-by: Scott Wood <scottwood@freescale.com>

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* NAND: ifdef-protect most of nand.h when using legacy NAND.Scott Wood2008-07-09-1/+4
| | | | | | | | 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. Signed-off-by: Scott Wood <scottwood@freescale.com>

* [patch] add nand_init() prototype to nand.hMike Frysinger2007-06-22-0/+1
| | | | | | | | since nand_init() is expected to be called by other parts of u-boot, there should be a prototype for it in nand.h Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Stefan Roese <sr@denx.de>
