From 82cd4adefe5a67870f2113498bdfe9350edd2078 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 30 Apr 2010 12:57:15 -0700 Subject: [PATCH] omap4: Fix multiboot with CONFIG_PM and CONFIG_ARCH_OMAP3 selected We cannot use the omap34xx_sram_init(). It needs to be implemented for omap4. Otherwise we get an error and the system won't boot: Unhandled fault: imprecise external abort (0x1406) at 0xea963e94 ... Fix this by adding a dummy omap44xx_sram_init().
