[U-Boot] mlo and u-boot

[Ryan]

Hello,

I am using AM43XX based board. The bootloader is divided into spl
u-boot (MLO) and u-boot.bin

I wanted to check what variables are shared between them. How does MLO
a seperate binary
share the boot mode and mmcdev to u-boot so that it can use the
appropriate mmcdev to find the
kernel.

thanks,
