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

[Gabriel Dobato <dobatog@gmail.com>]

Hello,

I am trying to boot the kernel image from SD-CARD (mmc0) in the CM-510 
SoM(provided by Compulab) using the u-boot image provided by Compulab:

http://www.compulab.co.il/products/computer-on-modules/cm-a510/#devres

By default, it seems SD-Card is not enabled, so I think I have to 
configure right the MPP option.

I have searched over and over in the code sources, I have change some 
arrays defined in some files that are related to the MPP (pinmux) but 
nothing happens:

./board/marvell/mv_dove/dove_family/boardEnv/mvBoardEnvSpec.h:

* DB-88F6781-BP B0 */
#define DB_88AP510BP_B_MPP0_7			0x00000000

./board/marvell/mv_dove/dove_family/boardEnv/mvBoardEnvSpec.c:
MV_BOARD_MPP_INFO	db88f6781bpbInfoBoardMppConfigValue[] =
	{{{{
	DB_88AP510BP_B_MPP0_7,		
	DB_88AP510BP_B_MPP8_15,		
	DB_88AP510BP_B_MPP16_23,
	DB_88AP510BP_B_MPP40_47	    <-------
	}}}};

Anyone has faced this problem before? I really appreciate some kind of help.

Best regards,

Gabriel
