Subject: [PATCH v2 2/4] ARM: imx8m: make debug UART selection available on i.MX8MM/MP
Date: Tue, 11 Aug 2020 11:43:28 +0200	[thread overview]
Message-ID: <20200811094330.4754-2-l.stach@pengutronix.de> (raw)
In-Reply-To: <20200811094330.4754-1-l.stach@pengutronix.de>

i.MX8MM/MN/MP has UARTs in the same place in the MMIO address space as
the i.MX8MQ, so make the lowlevel debug a bit more generic across the
i.MX8M family.

Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
---
v2:
- rebase on top of i.MX8MP support
- remove unused and redundant UART base address defines in SoC specific
  headers, the shared define in the familiy header is fine
