* Coding Style cleanup, update CHANGELOGWolfgang Denk2008-08-14-3/+3

* nand_spl: Support page-aligned read in nand_load, use chipselectGuennadi Liakhovetski2008-08-12-10/+20
| | | | | | | | | Supporting page-aligned reads doesn't incure any sinificant overhead, just a small change in the algorithm. Also replace in_8 with readb, since there is no in_8 on ARM. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>
* NAND boot: Update large page support for current API.Scott Wood2008-08-12-30/+20
| | | | | | | Also, remove the ctrl variable in favor of passing the constants directly, and remove redundant (u8) casts. Signed-off-by: Scott Wood <scottwood@freescale.com>
* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-2/+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>
* NAND: Update nand_spl driver to match updated nand subsystemStefan Roese2008-08-12-15/+19
| | | | | | | | | This patch changes the NAND booting driver nand_spl/nand_boot.c to match the new infrastructure from the updated NAND subsystem. This NAND subsystem was recently synced again with the Linux 2.6.22 MTD/NAND subsystem. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.SStefan Roese2008-06-03-6/+5
| | | | | | | | | | | | | | | | | This patch consolidates the 405 and 440 parts of the NAND booting code selected via CONFIG_NAND_SPL. Now common code is used to initialize the SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc. Only *after* running from this location, nand_boot() is called. Please note that the initsdram() call is now moved from nand_boot.c to start.S. I experienced problems with some boards like Kilauea (405EX), which don't have internal SRAM (OCM) and relocation needs to be done to SDRAM before the NAND controller can get accessed. When initdram() is called later on in nand_boot(), this can lead to problems with variables in the bss sections like nand_ecc_pos[].

* nand_spl: Update nand_spl to support 2k page size NAND devicesStefan Roese2008-04-18-1/+63
| | | | | | | | | This patch adds support for booting from 2k page sized NAND device (e.g. Micron 29F2G08AAC). Tested on AMCC Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>

* NAND: Add ECC support to NAND booting support in nand_spl/nand_boot.cStefan Roese2007-06-01-39/+56
| | | | | | | | | The U-Boot NAND booting support is now extended to support ECC upon loading of the NAND U-Boot image. Tested on AMCC Sequoia (440EPx) and Bamboo (440EP). Signed-off-by: Stefan Roese <sr@denx.de>

* Add support for AMCC Sequoia PPC440EPx eval boardStefan Roese2006-09-07-0/+178
- Add support for PPC440EPx & PPC440GRx - Add support for PPC440EP(x)/GR(x) NAND controller in cpu/ppc4xx directory - Add NAND boot functionality for Sequoia board, please see doc/README.nand-boot-ppc440 for details - This Sequoia NAND image doesn't support environment in NAND for now. This will be added in a short while. Patch by Stefan Roese, 07 Sep 2006
