* Monahans: avoid floating point calculationsWolfgang Denk2009-08-17-3/+5
| | | | | | | | | | | Current code for the Monahans CPU defined OSCR_CLK_FREQ as 3.250 (MHz) which caused floating point operations to be used. This resulted in unresolved references to some FP related libgcc functions when using U-Boot's private libgcc functions. Change the code to use fixed point math only.

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-33/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely.

* NAND finally working. Two bugs fixed:Markus Klotzbücher2006-03-06-8/+34
| | | | | | | | | * For READ_STATUS and READID commands always 8 bytes need to be read from NDDB. Otherwise they stay there and get send to flash as the first data word when writing. * In nand_base.c the oob variable is not reset so this->oob_buf is overwritten what eventually screws up the bad block descriptor table.
* Lots of new stuff:Markus Klotzbücher2006-03-04-67/+184
| | | | | | | | | | | * Debug message can be turned on and off. * Waiting for events now times out. * Implemented RESET command. * Added appropriate nand_bbt_descriptor and nand_oobinfo. Remaining Problems: * Read Status still behaves weird an returns invalid stuff sometimes. * ECC Placement does not respect our scheme in nand_oobinfo.
* Erasing works too now. The CS don't care causes problem with READSTATUS,Markus Klotzbücher2006-03-03-5/+10
