Subject: [PATCH v1 5/7] bus: mhi: core: Identify Flash Programmer as a mission mode use case
Date: Mon, 29 Mar 2021 18:28:22 -0700 [thread overview]
Message-ID: <1617067704-28850-6-git-send-email-bbhatt@codeaurora.org> (raw)
In-Reply-To: <1617067704-28850-1-git-send-email-bbhatt@codeaurora.org>
MHI power up can go through an EDL to Flash Programmer path when
the device has a blank NAND. In those cases, mhi_sync_power_up()
can timeout waiting for a mission mode execution environment.
Allow a successful power up instead by identifying Flash
Programmer as a valid mission mode execution environment with a
purpose to flash the device image contents.
