Subject: [PATCH v5 0/2] Enable capsule loader interface for efi firmware
From: "Kweh, Hock Leong" <hock.leong.kweh@...el.com>
Dear maintainers & communities,
This patchset is created on top of Matt's patchset:
1.)https://lkml.org/lkml/2014/10/7/390
"[PATCH 1/2] efi: Move efi_status_to_err() to efi.h"
2.)https://lkml.org/lkml/2014/10/7/391
"[PATCH 2/2] efi: Capsule update support"
It expose a misc char interface for user to upload the capsule binary and
calling efi_capsule_update() API to pass the binary to EFI firmware.
The steps to update efi firmware are:
1.) cat firmware.cap > /dev/efi_capsule_loader
2.) reboot
Any failed upload error message will be returned while doing "cat" through
Write() function call.
Tested the code with Intel Quark Galileo platform.
Thanks.
