Subject: [U-Boot] u-boot-xlnx 'master-next' branch: usb not working for microzed

Thanks to Michal - in the u-boot-xlnx/master-next (vs /master) the following
lines were removed:
board/xilinx/zynq/board.c:
-	/* temporary hack to take USB out of reset til the is fixed
-	 * in Linux
-	 */
-	writel(0x80, 0xe000a204);
-	writel(0x80, 0xe000a208);
-	writel(0x80, 0xe000a040);
-	writel(0x00, 0xe000a040);
-	writel(0x80, 0xe000a040);

This is board-specific (but the same for zedboard & microzed) USB reset
wired to MIO7. Without these lines USB reset stays active.

Thanks
