Subject: [PATCH 07/36] ARM: exynos: use private samsung_cpu_id copy
Date: Thu, 10 Oct 2019 22:29:51 +0200 [thread overview]
Message-ID: <20191010203043.1241612-7-arnd@arndb.de> (raw)
In-Reply-To: <20191010203043.1241612-1-arnd@arndb.de>
The only part of plat-samsung that is shared with arch-exynos
is the CPU identification code.
Having a separate exynos_cpu_id variable makes the two completely
independent and is actually a bit less code in total.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
