Subject: [PATCH v2] ARM: debug: add UART early console support for MSTAR SoCs
Date: Tue, 4 May 2021 19:03:16 +0200 [thread overview]
Message-ID: <20210504170316.34622-1-romain.perier@gmail.com> (raw)
This adds the debug_ll uart for the PM UART found on armv7-based MStar
SoCs.
Signed-off-by: Romain Perier <romain.perier@gmail.com>
Acked-by: Daniel Palmer <daniel@thingy.jp>

Changes since v1:
- Renamed to DEBUG_MSTARV7_PMUART, so it matches the arch name
- Improved the Kconfig description
- Added Daniel's Acked-by
