This patchset corrects and improves the device-tree
of the Zybo Z7 board
The first patch correct the RAM size
( supersedes https://lkml.org/lkml/2018/6/26/965 )
The second patch introduce the use of GPIO constants
to replace a literal
Finally, the third patch adds a gpio-leds node with
one LED
Luis Araneda (3):
arm: dts: zynq: Fix memory size on the Zybo Z7 board
arm: dts: zynq: Use gpio constants for the Zybo Z7 board
arm: dts: zynq: Add LEDs to the Zybo Z7 board

According to the reference manual, the board has two Micron
MT41K256M16HA-125 DDR3L memory ICs, which have 512 MiB each
Tested on a ZYBO-Z7-20 board
