[U-Boot] [PATCH 00/11 V12] EXYNOS5420: Add SMDK5420 board support
This patch adds basic board support for SMDK5420 board. These patches are tested for booting fine on EVT1 SMDK5420.
Changes in V2: - Corrected a compilation issue for SMDK5420.
Changes in V3: - Add patch to support variable size SPL support - Add patch to disable SMU for eMMC.
Changes in V4: - Added check for MAX77686 pmic compilation. - Added correct calculation of gpio based addresses. - Rebased on the latest u-boot code. - Removed patches for UART and TZPC changes as they were not needed. - Added flag to disable SMU for eMMC.
Changes in V5: - Moved functions board_mmc_init and board_eth_init to common/board.c in case of device tree support.
Changes in V6: - Rebased on the latest mainline branch. - Moved the definitions for SMU to arch/arm dwmmc.h
Changes in V7: - Removed below patch as it is already merged "DWMMC: SMDK5420: Disable SMU for eMMC" - Corrected the multi line comments and removal of blank spaces and lines. - Corrected the license.
Changes in V8: - corrected the if loops with if conditions of pro_id and cpu_id.
Changes in V9: - Added macros to get the base address - Rebased on latest code.
Changes in V10: - Added new structures for Power and DMC registers for 5420. - Changed the input parameters for common dmc functions. - Removed unnecesarry blank lines and added where ever required.
Changes in V11: -Rebased on latest u-boot-samsung branch.
Changes in V12: - Changed const void * pointers to uint32_t *.

When variable size SPL is used, the BL1 expects the SPL to be encapsulated differently: instead of putting the checksum at a fixed offset in the SPL blob, prepend the blob with a header including the size and the checksum.
The enhancements include - adding a command line option, '--vs' to indicate the need for the variable size encapsulation - padding the fixed size encapsulated blob with 0xff instead of random memory contents - do not silently truncate the input file, report error instead - no need to explicitly closing files/freeing memory, this all happens on exit; removing cleanups it makes code clearer - profuse commenting - modify Makefile to allow enabling the new feature per board
