From 41321fd4d64492689bfad20c98b8970171aee7ce Mon Sep 17 00:00:00 2001 From: SRICHARAN R Date: Thu, 17 May 2012 00:12:08 +0000 Subject: [PATCH] ARM: OMAP5: Align memory used for testing to the power of 2 get_ram_size checks the given memory range for valid ram, but expects the size of memory to be aligned to the power of 2. In case of OMAP5 evm board the memory available is 2GB - 16MB(used for TRAP section) = 2032MB. So always ensure that the size of memory used for testing is aligned to the power of 2.
