How to use both sdhc0 and sdhc1?

[jarodnan]

I'm developing a custom board base on the VF610 tower board. I'm planning to use the sdhc0 with an eMMC (MTFC4GLDDQ-4M IT ) with 8 bit data lines as the boot media, and sdhc1 as an external SD storage. What modifications should I make to the u-boot and linux kernel source code?

And it is possible to use an SD card to boot a newly made boar to make the onboard eMMC bootable? Just set BOOT_CFG to SD boot?
