Subject: [PATCH 0/3] ARM: add NAND support to Ebang EBAZ4205 board

Thanks to Miguel, there is finally a NAND driver for this SoC and we can
now support the NAND device on the EBAZ4205.

Btw. I'm not sure how often the PL35x NAND controller is used in SoC and
if it qualifies to add it to the multi_v7 defconfig.

Michael Walle (3):
ARM: configs: multi_v7: enable PL35x NAND controller
ARM: dts: zynq: add NAND flash controller node
ARM: dts: ebaz4205: enable NAND support

Subject: [PATCH 1/3] ARM: configs: multi_v7: enable PL35x NAND controller

After years, linux finally got a driver for the PL35x NAND controller
found on the Xilinx Zynq-7000 SoC for example. Enable support for this
driver.

Subject: [PATCH 3/3] ARM: dts: ebaz4205: enable NAND support

The board features a 128MiB NAND chip and recently linux gained support
for the NAND controller on the Zynq SoC. Thus add the corresponding
devicetree nodes.
