Subject: [PATCH 1/3] Input: add `SW_BOOT_ALT`
Date: Thu, 22 Sep 2022 12:12:09 +0200 [thread overview]
Message-ID: <20220922101211.3215888-2-foss+kernel@0leil.net> (raw)
In-Reply-To: <20220922101211.3215888-1-foss+kernel@0leil.net>
From: Quentin Schulz <quentin.schulz@theobroma-systems.com>
This event code represents the firmware source to use at boot.
Value 0 means using "standard" firmware source, value 1 means using
"alternative" firmware source.
For example, some hardware has the ability to force the BOOTROM to load
the bootloader from a secondary firmware source (say SD card) instead of
trying with the standard first and then the secondary. This event allows
the userspace to know which firmware source was requested *in hardware*.
