Used a script to recheck/verify pin mapping and existing mapping appears to be fine, returning correct bank and pin values. Did ./MAKEALL -a arm and found all Exynos/S5P related boards compiled successfully. Couldn't test booting over all of them. Tested U-Boot bootup over SMDK5420, SMDK5250, Snow. Requesting maintaners to please test over affected SoCs/boards.
Changes in V2: - Enabled CMD_GPIO as suggested by Simon Glass and supported same for EXYNOS5. Changes in V3: - New patch added to rename S5P GPIO definitions to S5P_GPIO. - GPIO Table added to calculate the base address of input gpio bank. Changes in V4: - To have consistent 0..n-1 GPIO numbering the banks are divided into different parts where ever they have holes in them. - Function and table to support gpio command moved to s5p-gpio driver. - Rebased on latest u-boot-samsung tree. Changes in V5: - Rebased on latest u-boot-samsung tree. - Removed Exynos5 specific code in gpio driver api to get bank. - Added #define HAVE_GENERIC_GPIO in config file to remove conditinal CPU check in gpio driver. Changes in V6: - Isolated config changes in a new patch. - Updated patches with corresponding changes for Exynos 5420. Changes in V7: - Added changes for other SoCs like Exynos 4412, 4210 etc. Changes in V8: - Changed Subject of patch 2/2 to reflect affected SoCs/boards. - Fixed arndale board compile time errors introduced due to patch-set v7. Changes in V9: - Fixed checkpatch errors. - Fixed naming error in exynosxxxx_gpio_data arrays which could be the possible reason behind data abort witnessed over Exynos4 boards.
