[U-Boot] U-Boot

[Mariano Coromac]

Hello Again,
I have been working with UBoot but now when I try to boot my Linux kernel
image that's inside my eMMC it displays the following:
=> boot
CMD_SEND:0
        ARG             0x00000000
        RET             -110
mmc_init: -110, time 10
** Bad device mmc 1 **
CMD_SEND:0
        ARG             0x00000000
        RET             -110
mmc_init: -110, time 11
** Bad device mmc 1 **

I know it is a timeout error and I also know that the error occurs inside
mmc-uclass line 31. I'm aware send_cmd() is defined in mmc.h but I honestly
don't know how to dig deeper into this error.

mmc info works fine. Here's the mmc rescan log if it makes any use:
=> mmc rescan

Any guidance would be appreciated.
Thank you.
