Subject: [PATCH 0/5] ARM: clean up after multiplatform changes
Date: Thu, 18 Aug 2022 16:56:11 +0200	[thread overview]
Message-ID: <20220818145616.3156379-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

Now that everything except StrongARM is unified under
CONFIG_ARCH_MULTIPLATFORM, the option is rather meaningless
in its current form.

Rework the Kconfig logic to make this useful again, similar
to the way that RISC-V has CONFIG_NONPORTABLE (with the
opposite polarity), this now controls the visibility of
options that get in the way of building generic kernels,
while allowing custom kernels.

One side-effect is that 'randconfig' builds now rarely hit
strongarm machines, rather than testing them three quarters
of the time.

Arnd Bergmann (5):
  ARM: remove obsolete Makefile.boot infrastructure
  ARM: simplify machdirs/platdirs handling
  ARM: Kconfig: clean up platform selection
  ARM: fix CPU_V6 dependencies
  ARM: make ARCH_MULTIPLATFORM user-visible
