NAND+MMC env support costs 12KB in the SPL which is fairly expensive just
for the ability to specify whether or not to boot to uboot or directly
to linux. The Ventana boards have plenty of EEPROM storage so we will use
a byte there to signify if we should boot to the bootloader or to the OS.

"net: phy: do not read configuration register on reset"

psu_init() function contains low level SoC setup generated for every HW
design by Xilinx design tools. xil_io.h is only supporting file to fix
all dependencies from tools. The same solution was used on Xilinx Zynq.
The patch also change CONFIG_SYS_INIT_SP_ADDR to the end of OCM which
stays at the same location all the time.
Bootrom expects starting address to be at 0xfffc0000 that's why this
address is SPL_TEXT_BASE.

The GIC ranges in the zynqmp device tree are only 4kb aligned. Since
commit 12e14066f we automatically deal with aliases GIC regions though,
so we can map them transparently into guests even on 64kb page size
systems.
This patch makes use of that features and sets GICC and GICV to 64kb
aligned and sized regions.
