From 995411953604e3c973328dda8c7807e45aca0f2b Mon Sep 17 00:00:00 2001 From: Afzal Mohammed Date: Tue, 13 Dec 2011 10:46:43 -0800 Subject: [PATCH 01/16] ARM: OMAP: am33xx: Update common omap platform files This patch updates the common platform files with AM335X device support (AM33XX family). The approach taken in this patch is, AM33XX device will be considered as OMAP3 variant, and a separate SoC class created for AM33XX family of devices with a subclass type for AM335X device, which is newly added device in the family. This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x() checks will return success on AM335X device. A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3 to include support for AM33XX build. Also, cpu_mask and RATE_IN_XXX flags have crossed 8 bit hence struct clksel_rate.flags, struct prcm_config.flags and cpu_mask are changed to u16 from u8.

The approach taken is to use TI81XX/ti81xx for code/data going to be common across all TI81XX devices. cpu_is_ti81xx() is introduced to handle code common across TI81XX devices. In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved in mach-omap2/common.c as same will be used for TI814X and is not board specific.
