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:

Any guidance would be appreciated.
Please check if there is a pin conflict to configure, or if the mmc
sequential number is correct.
On sama5d2 Xplained board, the eMMC works with the commands,
=> mmc info
Device: sdio-host@a0000000
Manufacturer ID: fe
OEM: 14e
Name: MMC04
Tran Speed: 52000000

Thank you.

Forget it guys, I just realized what was wrong.
reg = <0xf8038200 0x200>;
Before it was
reg = <0xf8038200 0x100>;
So if anyone else (that wants to use the flexcom uart) asks you
about this now there's another thing you can point to.
If I encounter another problem or something I'll get back to you.
