* ENGR00142322: mx53-smd: spi nor: can't erase 0x200000 sizeTerry Lv2011-04-20-13/+13
| | | | | | | | | | | | | Spi nor can't erase 0x200000 size. There are two issues in this CR. 1. Spi nor can't erase 0x200000 size. 2. Whole chip erase don't work. The solution will be: 1. Delay more time for WIP check. 2. Use normal erase for whole chip erase. Signed-off-by: Terry Lv <r65388@freescale.com>

| | | | | | | | | | Remove the 2G limitation from NAND driver since currently kernel can support more than 2GB NAND flash now. This commit will make NAND driver rescan the whole NAND to create one BBT and store to the last 4 blocks of the larger than 2GB NAND flash. This commit will have no effect on the NAND which size is not larger than 2GB. Signed-off-by: Jason Liu <r64343@freescale.com>

* ENGR00132617 MX53: add NAND supportLily Zhang2010-10-17-9/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | Add NAND support for MX53 EVK and ARD. Need to use kobs-ng to flash U-Boot on MX53 TO1. Because MX51 TO1 ROM doesn't support bi swap solution and kernel enable bi swap, Must enable "ignore bad block" option when flashing U-Boot. The step is as following: echo 1 > /sys/devices/platform/mxc_nandv2_flash.0/ignorebad kobs-ng init --chip_0_device_path=/dev/mtd2 u-boot.bin echo 0 > /sys/devices/platform/mxc_nandv2_flash.0/ignorebad Since default configuration stores environment into SD card and U-Boot uses get_mmc_env_devno (Read SBMR register) to get MMC/SD slot information, you must insert SD card to bottom SD slot to get/store environment if you are using NAND boot on MX53 EVK. You must config boot dip setting well when doing NAND boot. For example, if you are using NAND 29F32G080AA NAND chip on MX53 EVK, you can set boot dips as the following for NAND boot: SW3: dip 7, 8 on; SW2: dip 3,5 on; SW1: dip 4,7,8 on. Other dips are off.

* ppc4xx: Fix ECC Correction bug with SMC ordering for NDFC driverFeng Kan2009-08-25-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix ECC Correction bug where the byte offset location were double flipped causing correction routine to toggle the wrong byte location in the ECC segment. The ndfc_calculate_ecc routine change the order of getting the ECC code. /* The NDFC uses Smart Media (SMC) bytes order */ ecc_code[0] = p[2]; ecc_code[1] = p[1]; ecc_code[2] = p[3]; But in the Correction algorithm when calculating the byte offset location, the s1 is used as the upper part of the address. Which again reverse the order making the final byte offset address location incorrect. byteoffs = (s1 << 0) & 0x80; . . byteoffs |= (s0 >> 4) & 0x08; The order is change to read it in straight and let the correction function to revert it to SMC order.

| | | | | | | | | | | | Fix bug introduced by 9c048b523413ae5f3ff34e00cf57569c3368ab51. The cfi_flash.c driver cast the flash buffer size to a uchar in flash_write_cfibuffer(). On some flash parts, (tested on Numonyx part PC32F512M29EWH), the buffer size is 1KB. Remove the cast to uchar to enable buffer sizes to be larger.

* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-1663/+0
| | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.
