imx: mx6ul: support mx6ul 9x9 evk board
This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk, the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are: 1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC. 2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk supports 512MB DDR3 3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package. This patch add the following: 1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size() 2. Introduce a macro is_mx6ul_9x9_evk using CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work, so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with mx6ul_14x14_evk. And we have no way to dymaically checking this chip is 9x9 or 14x14. 3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations. POWER related configurations also effect for mx6ul_14x14_evk. But power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk. 4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM configurations. 5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file according to board_rev and board_name. 6. Add TARGET_MX6UL_9X9_EVK Kconfig entry Boot Log: U-Boot SPL 2015.10-rc2-00356-g536ce34 (Sep 06 2015 - 12:22:53) reading u-boot.img reading u-boot.img U-Boot 2015.10-rc2-00356-g536ce34 (Sep 06 2015 - 12:22:53 +0800) CPU: Freescale i.MX6UL rev1.0 792 MHz (running at 396 MHz) CPU: Commercial temperature grade (0C to 95C) at 41C Reset cause: POR Board: MX6UL 9x9 EVK I2C: ready DRAM: 256 MiB PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x11 MMC: FSL_SDHC: 0, FSL_SDHC: 1 In: serial Out: serial Err: serial Net: FEC1 Hit any key to stop autoboot: 0 Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Cc: Stefano Babic <sbabic@denx.de>
