When using OF_PLATDATA dtbs are converted to C structs in order to save space as we can remove both dtbs and libraries from TPL/SPL binaries.
This patchset tries to improve its support by overcoming some limitations in the current implementation
First, the support for scan and check for valid driver/aliases is added in order to generate U_BOOT_DEVICE entries with valid driver names.
Secondly, the way information about linked noded (phandle) is generated in C structs is improved in order to make it easier to get a device associated to its data.
Lastly the support for the property cd-gpios is added, which is used to configure the card detection gpio on MMC is added.
This implementation is based in discussion in [1], [2] and [3]
