[U-Boot] [PATCH 1/2] mxs: mxsboot: Move sdcard BCB header to 4 sectors offset

[Marek Vasut]

Dear Otavio Salvador,

> The MX23 Boot ROM does blindly load from 2048 offset while the MX28
> does parse the BCB header to known where to load the image from. We
> move the BCB header to 4 sectors offset so same code can be used by
> both SoCs avoiding code duplication.
