fastboot_partition_alias_boot=LNX
Raw partition descriptors
^^^^^^^^^^^^^^^^^^^^^^^^^
In cases where no partition table is present, a raw partition descriptor can be
defined, specifying the offset, size, and optionally the MMC hardware partition
number for a given partition name.
This is useful when using fastboot to flash files (e.g. SPL or U-Boot) to a
specific offset in the eMMC boot partition, without having to update the entire
boot partition.
To define a raw partition descriptor, add an environment variable similar to::
fastboot_raw_partition_<raw partition name>=<offset> <size> [mmcpart <num>]
for example::
fastboot_raw_partition_boot=0x100 0x1f00 mmcpart 1
Variable overrides
^^^^^^^^^^^^^^^^^^

Fastboot could implement setting of reboot reason in a generic fashion
via BCB commands. BCB commands are able to write reboot reason into
command field of boot control block. In general case it is sufficient
implementation if your platform supports BCB commands and doesn't
require any specific reboot reason handling.
