Subject: [PATCH 2/7] OMAP2+: use global values for the SRAM PA addresses
Date: Sat, 18 Dec 2010 16:44:42 +0100	[thread overview]
Message-ID: <1292687087-22983-3-git-send-email-j-pihet@ti.com> (raw)
In-Reply-To: <1292687087-22983-1-git-send-email-j-pihet@ti.com>

From: Jean Pihet <j-pihet@ti.com>

The SRAM PA addresses are locally defined and used at
different places, i.e. SRAM management code and idle sleep code.

The macros are now defined at a centralized place, for
easier maintenance.

Tested on N900 and Beagleboard with full RET and OFF modes,
using cpuidle and suspend.
