[U-Boot] sd card not working.

[U-Boot] sd card not working.

[Alexy Gallardo Segura]

Hello everyone

I am currently working with the ODROID-x2 platform and the U-boot that 
was using the u-boot by default, but support for the USB driver does not 
work well. Then I started to use the version available at:

https://github.com/LeMaker/u-boot

The USB works well. Probe the network and SD_CARD memories but now is 
not working for me. I am using an SD 8Gb.

Serious output is as follows:

U-Boot 2015.04-rc2 (Jun 24 2015 - 10:24:52)

  CPU:    Exynos4412 at 1000MHz

It seems that sd-card doesn't initialize completely.
-> "sdhci_transfer_data: Error detected in status(0x208000)!"

You can enable the MMC debug configuration.(CONFIG_MMC_TRACE)
Could you share the log message after enable CONFIG_MMC_TRACE?
