Subject: [PATCH 04/27] ARM: pxa: drop pxa310/pxa320/pxa93x support
Date: Thu,  5 Jan 2023 14:45:59 +0100	[thread overview]
Message-ID: <20230105134622.254560-5-arnd@kernel.org> (raw)
In-Reply-To: <20230105134622.254560-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

There is currently no devicetree support for any of these three
SoCs, and no board files remain. As it seems unlikely that anyone
is going to add DT support soon, let's drop the SoC specific code
now.
