[PATCH v2 0/7] ZynqMP: Cleanup and extend board support

This is v2 of the series to extend the ZynqMP ZCU104 board support.

This series adds support for reset source detection, Barebox environment,
barebox_update and soft reset (via PSCI) for the ZynqMP ZCU104 board. It
extends the zynqmp_defconfig to enable more features that you would probably
want by default on a ZynqMP board. I also added some introductory information
how to build and use Barebox on the ZynqMP.

Compared to v1, I removed the actually unused zynqmp.h file, and changed the
reset source from RESET_UKWN to RESET_JTAG on debugger reset.



- Set RESET_JTAG on debugger reset
- Remove unused zynqmp.h
