Notice the difference from QDS is SRC, SRC_ADDR and the offset of u-boot image
to match board NAND device with 4KB/page, block size 512KB.
+Booting from SD/eMMC
+-------------------
+Booting from SD/eMMC requires two images, RCW and u-boot-with-spl.bin.
+The difference between SD boot RCW image and QSPI-NOR boot image is the PBI
+command sequence. Below is one example for PBI commands for RDB and QDS which uses
+SD device with sector size 512.
+
+1) Block Copy: SRC=0x0040, SRC_ADDR=0x00100000, DEST_ADDR=0x1800a000,
+BLOCK_SIZE=0x00016000
+
+This command copies u-boot image from SD device into OCRAM. The values need
+to adjust accordingly for SD/eMMC
+
+SRC should match the cfg_rcw_src, the reset config pins. It depends
+ on the device will be SD(0x0040) or eMMC(0x0041).
+SRC_ADDR is the offset of u-boot-with-spl.bin image in SD device. In
+ the example above, 1MB. This is same as QSPI-NOR.
+DEST_ADDR is fixed at 0x1800a000, matching bootloc set above.
+BLOCK_SIZE is the size to be copied by PBI.
+
+2) CCSR 4-byte write to 0x01e00404, data=0x00000000
+3) CCSR 4-byte write to 0x01e00400, data=0x1800a000
+The above two commands set bootloc register to 0x00000000_1800a000 where
+the u-boot code will be running in OCRAM.
+
+
+RCW image should be written at 8th sector of device(SD/eMMC). Example of using
+u-boot command
+
+mc erase 0x8 0x10
+mmc write <rcw image in memory> 0x8 <size of rcw in sector count typical value= 10>
+
+To form the SD-Boot image, build u-boot with SD config, for example,
+ls1088ardb_sdcard_qspi_defconfig. The image needed is u-boot-with-spl.bin.
+The u-boot image should be written to match SRC_ADDR, in above example offset 0x100000
+in other work it means sector location 0x800
+
+mmc erase 0x800 0x1800
+mmc write <u-boot image in memory> 0x800 <size of u-boot image in sector count>
+
+With these two images in SD/eMMC device, the board can boot from SD/eMMC.
