Add Second MMC to LS1021A Device Tree

[Kensou]

Hello Everybody,

I would like to add a second eMMC in LS1021A with custom Buildroot Linux image and device tree for a custom board based on LS1021A-IOT board (with additional eMMC, of course).

Using Buildroot I am able to modify and customize the Linux Image.

What is the correct manner for adding additional peripherals?

LS1021A only has one esdhc controller, it is impossible to use a second MMC.

You could replace the SD interface with eMMC.
