[U-Boot] Rockchip RV1108 eMMC initialization fail

[alex94]

Hi,
I am trying to use eMMC as a storage medium for my
custom board based on Rockchip RV1108. 

I have already made the changes as described in this thread:

http://u-boot.10912.n7.nabble.com/Rockchip-RV1108-eMMC-support-not-working-td343843.html#a343866

about using eMMC with RV1108.

When U-boot starts, and I try to access the eMMC, here is what I get:

                RET                      -110


So, as the last line says, I get Linux error code -110, which means
"Connection timed out".

Here is info about the card I am using:

Flash Info:
	Manufacturer: SAMSUNG,value=00
	Flash Size: 7457MB
	Block Size: 512KB
	Page Size: 2KB
	ECC Bits: 0
	Access Time: 40
	Flash CS: Flash<0>

I have also tried with different SD cards on Rockchip MINI EVB RV1108 board, 
but I get the same error.

I get the same error with U-boot from Rockchip, and mainline U-boot from
Denx.

Any ideas?

Thanks,
Alex
