* Fix the NAND size overflow issue.Jason Jin2008-10-14-2/+2
| | | | | | | | | | | | | When the total size of all NAND devices exceeds 4 GiB, the size will overflow. This patch tries to fix this. Note that we still have a problem when a single NAND device is bigger than 4 GiB: then the overflow would actually happen earlier, i. e. when storing the size in nand_info[].size, as nand_info[].size is an "u_int32_t".

* cfi_flash: do not reset flash when probe failsMike Frysinger2008-10-02-1/+2
| | | | | | | | | | | | | | | The CFI flash driver starts at flash_init() which calls down into flash_get_size(). This starts by calling flash_detect_cfi(). If said function fails, flash_get_size() finishes by attempting to reset the flash. Unfortunately, it does this with an info->portwidth set to 0x10 which filters down into flash_make_cmd() and that happily smashes the stack by sticking info->portwidth bytes into a cfiword_t variable that lives on the stack. On a 64bit system you probably won't notice, but killing the last 8 bytes on a 32bit system usually leads to a corrupt return address. Which is what happens on a Blackfin system.

| * fsl_elbc_nand: implement support for flash-based BBTAnton Vorontsov2008-09-12-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements support for flash-based BBT for chips working through ELBC NAND controller, so that NAND core will not have to re-scan for bad blocks on every boot. Because ELBC controller may provide HW-generated ECCs we should adjust bbt pattern and bbt version positions in the OOB free area.

| * fsl_elbc_nand: fix OOB workability for large page NAND chipsAnton Vorontsov2008-09-12-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For large page chips, nand_bbt is looking into OOB area, and checking for "0xff 0xff" pattern at OOB offset 0. That is, two bytes should be reserved for bbt means. But ELBC driver is specifying ecclayout so that oobfree area starts at offset 1, so only one byte left for the bbt purposes. This causes problems with any OOB users, namely JFFS2: after first mount JFFS2 will fill all OOBs with "erased marker", so OOBs will contain: OOB Data: ff 19 85 20 03 00 ff ff ff 00 00 08 ff ff ff ff OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff And on the next boot, NAND core will rescan for bad blocks, then will see "0xff 0x19" pattern, and will mark all blocks as bad ones. To fix the issue we should implement our own bad block pattern: just one byte at OOB start. Though, this will work only for x8 chips. For x16 chips two bytes must be checked. Since ELBC driver does not support x16 NANDs (yet), we're safe for now.

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.
