Previously, few Amlogic devices supported EFI capsule updates. Generally only the Libre Computer ones with SPI flash supported it, thanks to board-specific code. This commit commonises capsule update support across supported Amlogic boards. Similar to Qualcomm's support for it, the dfu string and firmware name is automatically generated at runtime depending on which device we are booted from. Right now this supports flashing to the eMMC/SD and SPI flash. As usual, the capsule UUID is automatically generated. You can get it by enabling CONFIG_CMD_EFIDEBUG and running: => efidebug capsule esrt ======================================== ESRT: fw_resource_count=1 ESRT: fw_resource_count_max=1 ESRT: fw_resource_version=1 [entry 0]============================== ESRT: fw_class=796180D4-AAB2-50F1-B16A-53DFF9CA89B2 ESRT: fw_type=unknown ESRT: fw_version=0 ESRT: lowest_supported_fw_version=0 ESRT: capsule_flags=0 ESRT: last_attempt_version=0 ESRT: last_attempt_status=success ======================================== Reviewed-by: Evgeny Bachinin <EABachinin@salutedevices.com> Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Signed-off-by: Ferass El Hafidi <funderscore@postmarketos.org> Link: https://patch.msgid.link/20251211-meson-capsule-v4-1-59f126ba4115@postmarketos.org Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org>
