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 ...
