distro bootcmd: Allow board defined UBI partition and volume names
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
