[U-Boot] [PATCH] mxs: mxsboot: Add support for SD card generation for i.MX23

Dear Otavio Salvador,

Please fix the NAND support as well, then resubmit.

The patch basically does dd if=u-boot.sb ... bs=512 seek=4 ; any kind of 
information can be stored in those first four blocks and the mx23 bootrom 
ignores it, so what's the gain of this?

I wonder, will MX28 bootrom ignore them as well? Then maybe we can get rid of 
all this SD-specific junk.

Furthermore, I'd like to see all of this reworked as another plugin for mkimage.

Best regards,
Marek Vasut
