new port's shar
This port adds u-boot for Zybo Z7 board into ports collection. It is tested to build working binaries suitable for dropping into armv7-genericsd image's MSDOSBOOT partition to provide working system, just valid DTB file needs to be added to it (not part of this port, naturally).
Tested with currently used 2019.10 u-boot distfile, it works with recently released 2020.01 too (builds and boots).
Patches for two init issues are included in this port - there is bad clock in defconfig file for UART and two MIO pins are initialized incorrectly with pull-ups activated. Both are reported already upstream, but could not be included in release before 2020.04, naturally, so in the meantime use simple patches in this port.

Modifed shar file using patchwork
Can you have a look at this?
Oh god, shar ...
Well, I'm doing u-boot updates tonight, I'll see if it compiles and will commit it if it does.
This does not work with 2020.04
Please send a new patch (not shar please).
Note that the patches doesn't seems to be needed anymore.

New patch working with 2020.07 u-boot sources
This port was checked today for both build and boot functionality - raw make all install provide required files booting on my Zybo Z7 board with no intervention up to starting kernel.
This seems to be good to go now?
