| * NAND FSL elbc: Use virt_to_phys to determine which bank is in useKumar Gala2008-12-19-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | The current code that determines which bank/chipselect is used for a given NAND instance only worked for 32-bit addresses and assumed a 1:1 mapping. This breaks in 36-bit physical configs. The proper way to handle this is to use the virt_to_phys() and BR_PHYS_ADDR() routinues to match the 34-bit lbc bus address with the the virtual address the NAND code uses.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds basic UBI (Unsorted Block Image) support to U-Boot. It's based on the Linux UBI version and basically has a "OS" translation wrapper that defines most Linux specific calls (spin_lock() etc.) into no-ops. Some source code parts have been uncommented by "#ifdef UBI_LINUX". This makes it easier to compare this version with the Linux version and simplifies future UBI ports/bug-fixes from the Linux version.

* | cfi_flash: Make all flash access functions weakStefan Roese2008-11-24-7/+25
|/ | | | | | | | | | | | | | | | | This patch defines all flash access functions as weak so that they can be overridden by board specific versions. This will be used by the upcoming VCTH board support where the NOR FLASH unfortunately can't be accessed memory-mapped. Special accessor functions are needed here. To enable this weak functions you need to define CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS in your board config header. Otherwise the "old" default functions will be used resulting in smaller code.

* CFI Driver: Fix "flash not ready" problemWolfgang Denk2008-10-31-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem on systems where the NOR flash is attached to a 64 bit bus. The toggle bit detection in flash_toggle() is based on the assumption that the same flash address is read twice without any other interjacent flash accesses. However, on 32 bit systems the function flash_read64() [as currently implemented] does not perform an atomic 64 bit read - instead, this is broken down into two 32 bit read accesses on addresses "addr" and "addr + 4". So instead of reading a 64 bit value twice from "addr", we see a sequence of 4 32 bit reads from "addr", "addr + 4", "addr", and "addr + 4". The consequence is that flash_toggle() fails to work. This patch implements a simple, but somewhat ugly solution, as it avoids the use of flash_read64() in this critical place (by breaking it down manually into 32 bit read operations) instead of rewriting flash_read64() such to perform atomic 64 bit reads as one could expect. However, such a rewrite would require the use of floating point load operations, which becomes pretty complex: save MSR; set Floating Point Enable bit in MSR; use "lfd" instruction to perform atomic 64 bit read; use "stfd" to store value to temporary variable on stack; load u64 value from temporary variable; restore saved MSR; return u64 value; The benefit-cost ratio of such an implementation was considered too bad to actually attempt this, especially as we can expect that such an implementation would not only have a bigger memory footprint but also cause a performance degradation.

* 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: 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.
