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

[Gabriel Dobato <dobatog@gmail.com>]

Hi Dmitry,

Finally, I got the SD Card as a bootable kernel space. However I had to 
set the registers as below:

 >>>> #define CM_A510_MPP0_7                        0x00000033 (does not 
matter)
 >>>> #define CM_A510_MPP8_15                       0x00445050 (does not 
matter)
 >>>> #define CM_A510_MPP16_23                      0x33333333 <---- 
(SDIO0 and SDIO1)


Regards,

Gabriel
