[U-Boot] Ask for help: Compulab CM-510 U-boot version: Load Kernel from SD-Card

[Gabriel Dobato <dobatog@gmail.com>]

HI Dmitry,

Thank you very much for your answer!

I have tried it, but I get the same:

CM-A510>> mmc init
CM-A510>> mmcinfo 0
Device: MV_SDHCI
Manufacturer ID: 0
OEM: 0
Name: Tran Speed: 0
Rd Block Len: 0
MMC version 0.0
High Capacity: No
Capacity: 0
Bus Width: 0-bit

In reference to peripherals, only is available USB and Ethernet 0 by 
default. I am searching in the sources just in case there is something 
else... but I am afraid I will not find something.

By the way, how do you get that resgisters? In my case, I tried to 
define them as per as Marvell 88AP510 Specification reference. Is it the 
right place?

Best regards,

Gabriel
