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.
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.
