board: samsung: e850-96: Enable EFI Capsule Update mechanism
Make it possible to update E850-96 firmware binaries using EFI Capsule
Update mechanism. For example, to update the U-Boot binary, the capsule
file can be generated like this:
$ ./tools/mkeficapsule --index 4 \
--guid 629578c3-ffb3-4a89-ac0c-611840727779 \
u-boot.bin capsule4.bin
The resulting 'capsule4.bin' should be copied to ESP partition (in
/boot/efi/EFI/UpdateCapsule/ directory). Then after reboot U-Boot will
update the 'bootloader' area in eMMC Boot Partition A (boot0) and remove
the capsule file, by EFI boot manager executed as a part of Standard
Boot:
Applying capsule capsule4.bin succeeded.
Reboot after firmware update.
The kernel will also expose the ESRT table information via SysFS in
/sys/firmware/efi/esrt/entries.
