Subject: [PATCH 3/3] [v3] davinci: da850: changed SRAM allocator to shared ram.
Date: Wed,  1 Jun 2011 11:03:25 -0400	[thread overview]
Message-ID: <9abf8b57b0b664ffc262af63bd0495e9d7c09230.1306940448.git.bengardiner@nanometrics.ca> (raw)

Changes since v2:
 * Added Jean-Christophe PLAGNIOL-VILLARD's Ack
Changes since v1:
 * re-sorted the new DA8XX_SHARED_RAM_BASE definition in  da8xx.h
   to between DA8XX_AEMIF_CTL_BASE and DA8XX_DDR2_CTL_BASE (Sergei
   Shtylyov).
