This patch is for SPL support for iMX6 SabreSD. The said patches has been tested to work on SD2 and SD3 port of the said board. It tested the non-spl version of uboot as well.
After applying the following patches, it will produces SPL and u-boot.img binary images. You should run the two commands below to store it in your SD or eMMC. sudo dd if=SPL of=/dev/xxx bs=1K seek=1; sync sudo dd if=u-boot.img of=/dev/xxx bs=1K seek=69 Changes (v2): Merged the SPL support into the main board file Remove the compilation warmings Changes (v3): Removed sp and gd Use imx_ddr_size to set the ram_size Changes (v4): Add a separate board configuration file to enable SPL (mx6sabresd_spl_defconfig). Mapped DCD data to mx6_mmdc_calibration, mx6dq_iomux_grp_regs, mx6dq_iomux_ddr_regs and mx6_ddr3_cfg data structures. Read 11 and 12 bits of BOOT_CFG register to actually determine the active mmc port. Changes (v5): Use the default CONFIG_SPL_STACK Add a macro #ifndef for CONFIG_SYS_TEXT_BASE to avoid compilation warning. Changes (v6): Use board_mmc_init for spl mmc initialization instead of adding spl_board_mmc_init function Changes (v7): Corrected the chip select value and now the DRAM showing a correct 1 GiB.
