SECT_4K, SECT_32K and SECT_64K opeartions are performed to to specific flash by adding a SECT* flag on respective spi_flash_params.flag param. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>
2013-10-07sf: probe: Add support to clear flash BP# bitsJagannadha Sutradharudu Teki
Few of the flashes(Atmel, Macronix and SST) require to clear BP# bits in flash power ups. So clear these BP# bits at probe time, so-that the flash is ready for user operations. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>

2013-09-11mxs_nand: Fix ECC strength for NAND flash with OOB size of 224Elie De Brauwer
On a board with an i.mx28 and a Micron MT29F4G08ABAEAH4, Linux says: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micron MT29F4G08ABAEAH4), 512MiB, page size: 4096, OOB size: 224) the ECC strength is 16. root@(none):/sys/devices/virtual/mtd/mtd0# for i in ecc_strength oobsize subpagesize; do echo $i = `cat $i`; done ecc_strength = 16 oobsize = 224 subpagesize = 4096 The ECC strength was not properly discovered by U-Boot causing the data written by Linux to return an -74 (EBADMSG) when read from U-Boot. This patch fixes mxs_nand_get_ecc_strength() to function in case of a NAND flash with page_data_size = 4096 and page_oob_size= 224.

2013-09-04mtd: atmel_nand: pmecc: fix bug fail to correct bit error in 1024-bytes sectorWu, Josh
The PMECC use BCH algorithm to correct error. In BCH algorithm, the primitive polynomial value is GF(2^13) for 512-bytes sector size. And it is GF(2^14) for 1024-bytes sector size. This patch will choose correct degree of the remainders (13 or 14) for different sector size. Tested in AT91SAM9X5-EK with MLC nand flash.

1. if CONFIG_SYS_NAND_ONFI_DETECTION is defined, driver will check NAND flash's ecc minimum requirement in ONFI parameter. a) if CONFIG_PMECC_CAP, CONFIG_PMECC_SECTOR_SIZE are defined. then use it. Driver will display a WARNING if the values are different from ONFI parameters. b) if CONFIG_PMECC_CAP, CONFIG_PMECC_SECTOR_SIZE are not defined, then use the value from ONFI parameters. * If ONFI ECC parameters are in ONFI extended parameter page, since we are not support it, so assume the minimum ecc requirement is 2 bits in 512 bytes. * For non-ONFI support nand flash, also assume the minimum ecc requirement is 2 bits in 512 bytes. 2. if CONFIG_SYS_NAND_ONFI_DETECTION is not defined, just use CONFIG_PMECC_CAP and CONFIG_PMECC_SECTOR_SIZE.

2013-08-20powerpc : spi flash : Support to start from eSPI with SPLYing Zhang
This patch introduces SPL to enable a loader stub that being loaded by the code from the internal on-chip ROM. It loads the final uboot image into DDR, then jump to it to begin execution. The SPL's size is sizeable, the maximum size must not exceed the size of L2 SRAM. It initializes the DDR through SPD code, and copys final uboot image to DDR. So there are two stage uboot images: * spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that ddr spd code can get the interleaving mode setting in env. It loads final uboot image from offset 96KB. * final uboot image, size is variable depends on the functions enabled.

2013-07-25cfi_flash: use buffer length in unmap_physmem()Kuo-Jung Su
While the flash_detect_legacy() of drivers/mtd/cfi_flash.c feed unmap_physmem() with MAP_NOCACHE as 2nd parameter, the do_spi_flash_read_write() of common/cmd_sf.c feed unmap_physmem() with the length of the mapped buffer as 2nd parameter. It's apparently a bug, and I personally think the 2nd parameter should be the length of the mapped buffer.
