Subject: [PATCH 2/3] ARM: brcmstb: Enable ARCH_HAS_HOLES_MEMORYMODEL
Date: Thu, 9 Mar 2017 10:51:19 -0800 [thread overview]
Message-ID: <20170309185120.1713-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20170309185120.1713-1-f.fainelli@gmail.com>
From: Danesh Petigara <danesh.petigara@broadcom.com>
Due to the brcmstb SoC's memory map, we may have holes in the memory if
we don't populate the maximum amount of memory supported by e.g: the
first memory controller which spans either the first 1GiB or first 2GiB
of memory.
We need to select ARCH_HAS_HOLES_MEMORYMODEL in order to enable
CONFIG_HAVE_ARCH_PFN_VALID on platforms that have CONFIG_SPARSEMEM
enabled.
