Subject: [PATCH 4/6] mmc: add FFU support to card/block.c
Date: Wed, 13 Apr 2016 15:33:42 -0700 [thread overview]
Message-ID: <1460586824-40688-5-git-send-email-gwendal@chromium.org> (raw)
In-Reply-To: <1460586824-40688-1-git-send-email-gwendal@chromium.org>
From: Grant Grundler <grundler@google.com>
Add special case in MMC_IOC_CMD to process FFU command from mmc tool.
A FFU command is similar to a multi command, but it also require loading
firmware and maybe reset the device.
