[U-Boot] [PATCH v3 0/5] Add support for MIPS Creator CI20

[Ezequiel Garcia]

A new round, addressing feedback from Daniel.

Daniel: do you think this is acceptable as a first submission?

v3:
 * Cleanup SoC reset logic.
 * Move gpio driver to SoC specific code, to be used by SPL.
   A proper dm gpio driver will be added later.
 * Cleaned up SPDX.
 * Added myself as JZ4780 maintainer.
 * Added TODO file.

v2:

 * Replaced infinite while loop with wait_for_bit.
 * Added a MAINTAINERS file. If anyone wants to co-maintain this,
   please let me know.

This is based on master and has been tested by SD-card booting
both U-Boot and Linux. Booting Linux via TFTP was also tested.

I've pushed a branch to https://github.com/ezequielgarcia/u-boot/tree/ci20-v3
and started travis.

Note that Paul's contributions are recorded using his imgtec.com
mail although it's no longer valid, and that we will rely on mailmap
to map it to mips.com.

It would be terrific to fit this on the next release.

Thanks!
