| * | | | | | mpc8313, signed fit: enable legacy image format on ids8313 boardHeiko Schocher2014-06-05-0/+1

| * | | | | | bootm: make use of legacy image format configurableHeiko Schocher2014-06-05-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | make the use of legacy image format configurable through the config define CONFIG_IMAGE_FORMAT_LEGACY. When relying on signed FIT images with required signature check the legacy image format should be disabled. Therefore introduce this new define and enable legacy image format if CONFIG_FIT_SIGNATURE is not set. If CONFIG_FIT_SIGNATURE is set disable per default the legacy image format.

When SPL booting, this is handled by setting gd to point to SRAM in s_init. However in the cases where we are loaded directly by ROM (memory mapped NOR or QSPI) we need to make use of the normal hooks to slightly delay these calls. Signed-off-by: Tom Rini <trini@ti.com>

Thus stronger ECC schemes are required for protecting the data. But stronger ECC schemes have come with larger-sized ECC syndromes which require more space in OOB/Spare. This puts constrains like; (a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data. (b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B. Due to (b) this scheme can only be used with NAND devices which have enough OOB to satisfy following equation: OOBsize per page >= 26 * (page-size / 512) Signed-off-by: Pekon Gupta <pekon@ti.com>

Also, dynamic detection of NAND bus-width from on-chip ONFI parameters is not possible in following situations: SPL: SPL NAND drivers does not support ONFI parameter reading. U-boot: GPMC controller iniitalization is done in omap_gpmc.c:board_nand_init() which is called before probing for devices, hence any ONFI parameter information is not available during GPMC initialization. Thus, OMAP NAND driver expected board developers to explicitely write GPMC configurations specific to NAND device attached on board in board files itself. But this was troublesome for board manufacturers as they need to dive into lengthy platform & SoC documents to find details of GPMC registers and appropriate configurations to get NAND device working. This patch instead adds existing CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config hich indicates that connected NAND device has x16 bus-width. And then based on this config GPMC driver itself initializes itself based on NAND bus-width. This keeps board developers free from knowing GPMC controller specific internals.

The host shall not issue commands that use a word data width on x16 devices until the host determines the device supports a 16-bit data bus width in the parameter page." *Section: Bus Width Requirements* "When the host supports a 16-bit bus width, only data is transferred at the 16-bit width. All address and command line transfers shall use only the lower 8-bits of the data bus. During command transfers, the host may place any value on the upper 8-bits of the data bus. During address transfers, the host shall set the upper 8-bits of the data bus to 00h."
