From 455d4d2dc76471baec0c70daf8ff6c09fc743c24 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar 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.
