Subject: [PATCH AUTOSEL 4.19 55/81] ARM: 8856/1: NOMMU: Fix CCR register faulty initialization when MPU is disabled
Date: Tue, 7 May 2019 01:35:26 -0400 [thread overview]
Message-ID: <20190507053554.30848-55-sashal@kernel.org> (raw)
In-Reply-To: <20190507053554.30848-1-sashal@kernel.org>
From: Tigran Tadevosyan <tigran.tadevosyan@arm.com>
[ Upstream commit c3143967807adb1357c36b68a7563fc0c4e1f615 ]
When CONFIG_ARM_MPU is not defined, the base address of v7M SCB register
is not initialized with correct value. This prevents enabling I/D caches
when the L1 cache poilcy is applied in kernel.
Fixes: 3c24121039c9da14692eb48f6e39565b28c0f3cf ("ARM: 8756/1: NOMMU: Postpone MPU activation till __after_proc_init")
