[PATCH v3 00/14] improve OF_PLATDATA support

[Walter Lozano]

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]

Changes for v3
- Split patches to separate core from tools changes
- Squash patches to avoid errors on tests
- Fix lines longer than 80 chars

Changes for v2
- Rename drivers to match compatible strings
- Fix out-of-trees usage of dtoc
- Fix test coverage
- Improve documentation
- Improve format
