To enable local Timers for es1.0, I made some progress but looks like it needs more changes in generic code. Will have a look at it tomorrow. The patch is on top of the patches being discussed here. It's boot-tested with single image on OMAP3 and OMAP4 SMP. >From 26c908cd9baf3cc0b22f04f29cbeb26e08ad05e8 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar <santosh.shilimkar@xxxxxx> Date: Wed, 15 Sep 2010 22:40:19 +0530 Subject: [PATCH] omap: Update and rename common defconfig for omap2plus devices This patch addresses below things: - Renaming existing omap3_defconfig which has OMAP2, OMAP3 and OMAP4 builds enabled to more appropriate name 'omap2plus_defconfig' - L1 cache shift is suppose to be 5 on OMAP4 where as it is 6 on previous OMAPs. Keeping it to 5 is safer option for OMAP4 and previous OMAPs. For OMAP3 only build the shift would be still 6 - Enable needed Errata's for OMAP4 to work with DMA based device drivers CONFIG_PL310_ERRATA_588369=y CONFIG_ARM_ERRATA_720789=y - Enable the Micrel ethernet controller CONFIG_KS8851=y CONFIG_KS8851_MLL=y With above three changes, OMAP4 ethernet, mmc etc works reliably.
