Subject: [PATCH v1 0/7] Remove ARM platform efm32
Date: Thu, 14 Jan 2021 16:16:23 +0100	[thread overview]
Message-ID: <20210114151630.128830-1-u.kleine-koenig@pengutronix.de> (raw)

From: Uwe Kleine-König <uwe.kleine-koenig@pengutronix.de>

Hello,

there are no known active users of the efm32 platform. Given that the
only machine that is supported has only 4 MiB of RAM its use is also
quite limited.

Back then it served as the platform to develop ARMv7-M support in Linux
which was quite fun and still is a blissful memory.

Still given that the code serves no purpose and this probably won't
change anytime soon, remove all platform support.

I'm unsure what to do with the device tree bindings. Should we delete
them, too?

Best regards
Uwe
