This commit allows overriding the default assumption that the boot UBI MTD partition is named 'UBI' and the UBI volume is 'boot'. A board desiring to use a legacy or alternative NAND layout can now define the following two extra environment variables:
bootubipart=<some_ubi_partition_name> bootubivol=<some_ubi_volume_name>
EXAMPLE:
[include/configs/some_board.h] ---8<------------------------------------------------------------------- [...] #include <config_distro_defaults.h>
#define MEM_LAYOUT_ENV_SETTINGS \ DEFAULT_LINUX_BOOT_ENV
#define BOOT_TARGET_DEVICES(func) \ func(UBIFS, ubifs, 0)
#include <config_distro_bootcmd.h> [...] #define CONFIG_EXTRA_ENV_SETTINGS \ MEM_LAYOUT_ENV_SETTINGS \ "bootubivol=rootfs\0" \ "bootubipart=rootfs\0" \ BOOTENV [...] ---8<-------------------------------------------------------------------
