Subject: [PATCH 0/8] ARM: i.MX7: add serial download reboot mode
Date: Mon, 17 Oct 2022 09:09:52 +0200 [thread overview]
Message-ID: <20221017071000.1458292-1-a.fatoum@pengutronix.de> (raw)
BootROM can be forced into USB recovery on i.MX7 just like on the
i.MX8M, with the difference that reset is a bit more involved,
because warm resets via watchdogs are broken on this SoC.
We do a bit of cleanup and then tackle that via a syscon-reboot
device describing the Cortex-A7 CPU0 reset.
Ahmad Fatoum (8):
restart: make restart.h header self-contained
restart: do restart-priority OF parsing in restart_handler_register
restart: add reset -w for warm bootrom reset
watchdog: imxwd: don't register broken imxwd-warm for i.MX7
watchdog: imxwd: set imxwd-warm as reboot mode default handler
Documentations: devicetree: bindings: document watchdog-priority
ARM: i.MX7: describe USB serial download boot mode
ARM: stm32mp: mark iwdg2 with barebox,restart-warm-bootrom
