Subject: [Buildroot] [PATCH 3/4] arch/{Config.in, arch.mk}.xtensa: add explicit support for DC233C core
Date: Sat, 24 Sep 2022 22:53:25 +0200	[thread overview]
Message-ID: <20220924205327.1489102-3-thomas.petazzoni@bootlin.com> (raw)
In-Reply-To: <20220924205327.1489102-1-thomas.petazzoni@bootlin.com>

The DC233C Xtensa core is the one used by our Qemu Xtensa
defconfigs, and it is a little endian core. It makes sense to promote
it as a supported Xtensa core in arch/Config.in.xtensa, so that our
autobuilder testing covers build testing of little endian Xtensa
configurations. Indeed currently, both the FSF core and the custom
core are big endian (the custom core cannot be little endian without
an overlay).
