From 00bbe96ebabbc83777cd8d6c6fd2791c5c8cf619 Mon Sep 17 00:00:00 2001 From: Semen Protsenko Date: Fri, 2 Jun 2017 18:00:00 +0300 Subject: arm: omap: Unify get_device_type() function Refactor OMAP3/4/5 code so that we have only one get_device_type() function for all platforms. Details: - Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for OMAP4/5), so we can obtain status register in common way - For now ctrl structure for AM33xx/OMAP3 contains only status register address - Run hw_data_init() in order to assign ctrl to proper structure - Remove DEVICE_MASK and DEVICE_GP definitions as they are not used (DEVICE_TYPE_MASK and GP_DEVICE are used instead) - Guard structs in omap_common.h with #ifdefs, because otherwise including omap_common.h on non-omap4/5 board files breaks compilation Buildman script was run for all OMAP boards. Result output: arm: (for 38/616 boards) all +352.5 bss -1.4 data +3.5 rodata +300.0 spl/u-boot-spl:all +284.7 spl/u-boot-spl:data +2.2 spl/u-boot-spl:rodata +252.0 spl/u-boot-spl:text +30.5 text +50.4 (no errors to report) Tested on AM57x EVM and BeagleBoard xM.
