[PATCH v4 4/8] board: Define set_dfu_alt_info() for boards with UEFI capsule update enabled
Sughosh Ganu
sughosh.ganu at linaro.org
Thu Mar 31 15:27:46 CEST 2022
Currently, there are a bunch of boards which enable the UEFI capsule
update feature. The actual update of the firmware images is done
through the dfu framework which uses the dfu_alt_info environment
variable for getting information on the update, like device, partition
number/address etc. Currently, these boards define the dfu_alt_info
variable in the board config header, as an environment variable. With
this, the variable can be modified from the u-boot command line and
this can cause an incorrect update.
To prevent this from happening, define the set_dfu_alt_info function
in the board file, and select SET_DFU_ALT_INFO for all platforms which
enable the capsule update feature. With the function defined, the dfu
framework populates the dfu_alt_info variable through the board file,
instead of fetching the variable from the environment, thus making the
update more robust.

Changes since V3:
* Do not remove the existing dfu_alt_info definitions made by
platforms in the config files, as discussed with Masami.
* Squash the selection of the SET_DFU_ALT_INFO config symbol for
capsule update feature as part of this patch.
