km/common: add support for second flash
Add support for a second flash. By default, a single flash chip is set up: - called 'boot' - mtd name for ubi 'ubi0' MTDIDS and MTDPARTS may be overwritten to add a second flash. The 'ubiattach' command is featured in two versions: - if CONFIG_KM_UBI_PARTITION_NAME_APP is not defined: this is the version as up to now - if CONFIG_KM_UBI_PARTITION_NAME_APP is defined: a check on 'actual_bank' will be done to determine the flash to boot from. Use CONFIG_KM_UBI_PARTITION_NAME_BOOT and CONFIG_KM_UBI_PARTITION_NAME_APP to define where to put the bootloader and the applications. Example: In the board config do: ... snip ... "boot:" \ "768k(u-boot)," \ "128k(env)," \ "128k(envred)," \ "-(" CONFIG_KM_UBI_PARTITION_NAME_BOOT ");" \ "app:" \ "-(" CONFIG_KM_UBI_PARTITION_NAME_APP ");" ... snap ... You may also need to enable the second flash: ... snip ... /* additional featured for COGE5 */ ... snap ...
