Subject: [PATCH v3 1/3] of/fdt: Absorb ARM64's __early_init_dt_declare_initrd()
Date: Wed, 24 Oct 2018 17:17:40 -0700	[thread overview]
Message-ID: <20181025001742.6510-2-f.fainelli@gmail.com> (raw)
In-Reply-To: <20181025001742.6510-1-f.fainelli@gmail.com>

ARM64 is the only architecture that requires a re-definition of
__early_init_dt_declare_initrd(), absorb its custom implemention in
drivers/of/fdt.c.
