[U-Boot] [PATCH 1/1] arm: zynq: Fix device tree for Avnet Picozed boards

[Andreas Galauner <andreas@galauner.de>]

This change adds the necessary /chosen/stdout-path to the device tree
for the Avnet Picozed boards. This node is mandatory for the SPL. Without
it the board resets in a loop without any output. The change also adds
the USB, QSPI and Ethernet MAC nodes of the corresponding devices present
on the board.
