[U-Boot] [PATCH v2 0/6] Add support for MIPS Creator CI20

[Ezequiel Garcia]

A new round.

For this new round:

 * 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 top of yesterday's master (ee168783ae8) and has
been tested by SD-card booting both U-Boot and Linux. Booting
Linux via TFTP was also tested.

Toolchain used to test:

$ mips-linux-gcc -v
Using built-in specs.
COLLECT_GCC=mips-linux-gcc
COLLECT_LTO_WRAPPER=/home/zeta/.buildman-toolchains/gcc-7.3.0-nolibc/mips-linux/bin/../libexec/gcc/mips-linux/7.3.0/lto-wrapper
Target: mips-linux
Configured with: /home/arnd/git/gcc/configure --target=mips-linux --enable-targets=all --prefix=/opt/crosstool/gcc-7.3.0-nolibc/mips-linux --enable-languages=c --without-headers --disable-bootstrap --disable-nls --disable-threads --disable-shared --disable-libmudflap --disable-libssp --disable-libgomp --disable-decimal-float --disable-libquadmath --disable-libatomic --disable-libcc1 --disable-libmpx --enable-checking=release
Thread model: single
gcc version 7.3.0 (GCC) 

SPL size:

$ size spl/u-boot-spl
   text	   data	    bss	    dec	    hex	filename
   9252	    752	    736	  10740	   29f4	spl/u-boot-spl

I've pushed a branch to https://github.com/ezequielgarcia/u-boot/tree/ci20-v2
and made sure travis passed.

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mail although it's no longer valid, and that we will rely on mailmap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!
