Subject: [PATCH 0/6] misc: add reboot mode driver
Date: Mon, 21 Dec 2015 19:27:29 +0800 [thread overview]
Message-ID: <1450697249-29994-1-git-send-email-andy.yan@rock-chips.com> (raw)
This driver parse the reboot commands like "reboot loader"
and "reboot recovery" to get a boot mode described in the
device tree , then call the vendor specific write interfae
to store the boot mode in some place like special register
or sram , which can be read by the bootloader after system
reboot.
This is commonly done on Android based devices, in order to
reboot the device into fastboot or recovery mode.
Before this patch , I have try some hack on[0], and then found
John Stultz also doing the same work[1].
As John is busy these days, I go on with this work.
