Subject: [PATCH v2 08/19] SEAD3: Probe parallel flash via DT
Date: Fri, 26 Aug 2016 15:17:40 +0100 [thread overview]
Message-ID: <20160826141751.13121-9-paul.burton@imgtec.com> (raw)
In-Reply-To: <20160826141751.13121-1-paul.burton@imgtec.com>
Probe the system parallel flash using device tree rather than platform
code, in order to reduce the amount of the latter.
Signed-off-by: Paul Burton <paul.burton@imgtec.com>

Changes in v2:
- Provide bank-width
- Move partitions beneath partitions node
- s/pflash/flash/
