Subject: [PATCH 3/3] MIPS: Malta: Implement mips_cdmm_phys_base()
Date: Tue, 27 Jan 2015 21:16:41 +0000	[thread overview]
Message-ID: <1422393401-13543-4-git-send-email-james.hogan@imgtec.com> (raw)
In-Reply-To: <1422393401-13543-1-git-send-email-james.hogan@imgtec.com>

Implement mips_cdmm_phys_base() for Malta, returning the physical base
address 0x1fc10000 which is "typically unused".

This allows the Common Device Mapped Memory (CDMM) region to be mapped,
and devices in that region (such as the Fast Debug Channel (FDC)
hardware for communication over EJTAG) to be discovered.
