Subject: [PATCH v3 5/5] rockchip: rk3399: Add bootcount support
Date: Mon, 30 Dec 2019 00:37:26 +0530 [thread overview]
Message-ID: <20191229190726.29266-6-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191229190726.29266-1-jagan@amarulasolutions.com>
Add bootcount support for Rockchip rk3399.
The bootcount value is preserved in PMU_SYS_REG0 register,
this would help to support redundent boot.
Once the redundant boot triggers, the altboot command
will look for extlinux-rollback.conf on particular
bootable partition which supposed to be a recovery
partition where redundant boot required.
