Subject: [PATCH 2/6] arch: Make phys_initrd_start and phys_initrd_size global variables
Date: Mon, 29 Oct 2018 16:52:02 -0700	[thread overview]
Message-ID: <20181029235206.30060-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20181029235206.30060-1-f.fainelli@gmail.com>

Make phys_initrd_start and phys_initrd_size global variables that will
later be referenced by generic code under drivers/of/fdt.c.
