2013-06-23sf: Update sf to support all sizes of flashesJagannadha Sutradharudu Teki
Updated the spi_flash framework to handle all sizes of flashes using bank/extd addr reg facility The current implementation in spi_flash supports 3-byte address mode due to this up to 16Mbytes amount of flash is able to access for those flashes which has an actual size of > 16MB. As most of the flashes introduces a bank/extd address registers for accessing the flashes in 16Mbytes of banks if the flash size is > 16Mbytes, this new scheme will add the bank selection feature for performing write/erase operations on all flashes.

This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

When base address given was out of valid flash address ranges, flash_get_info() function returned the pointer to the last element of flash_info[i] array. This patch changes this function to return NULL pointer in such a case, which is more correct behaviour. The function flash_protect_default() calls flash_protect() immediately after flash_get_info() invocation.

Packed structure cfi_qry contains unaligned 16- and 32-bits members, accessing which causes problems when cfi_flash driver is compiled with -munaligned-access option: flash initialization hangs, probably due to data error. Since the structure is supposed to replicate the actual data layout in CFI Flash chips, the alignment issue can't be fixed in the structure. So, unaligned fields need using of explicit unaligned access macros.

2013-05-05mtd: nand: add driver for diskonchip g4 nand flashMike Dunn
This patch adds a driver for the diskonchip G4 nand flash device. It is based on the driver from the linux kernel. This also includes a separate SPL driver. A separate SPL driver is used because the device operates in a different mode (reliable mode) when loading a boot image, and also because the storage format of the boot image is different from normal data (pages are stored redundantly). The SPL driver basically mimics how a typical IPL reads data from the device. The special operating mode and storage format are used to compensate for the fact that the IPL does not contain the BCH ecc decoding algorithm (due to size constraints). Although the u-boot SPL *could* use ecc, it operates like an IPL for the sake of simplicity and uniformity, since the IPL and SPL share the task of loading the u-boot image. As a side benefit, the SPL driver is very small. [port from linux kernel 3.4 commit 570469f3bde7f71cc1ece07a18d54a05b6a8775d] Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
