Subject: [PATCH v2 1/3] libahci: save port map for forced port map
Date: Thu, 31 Mar 2016 18:31:38 +0100 [thread overview]
Message-ID: <1459445500-9071-2-git-send-email-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <1459445500-9071-1-git-send-email-srinivas.kandagatla@linaro.org>
In usecases where force_port_map is used saved_port_map is never set,
resulting in not programming the PORTS_IMPL register as part of initial
config. This patch fixes this by setting it to port_map even in case
where force_port_map is used, making it more inline with other parts of
the code.
