This adds support the Xilinx ZCU106 development board.

[Tested on the ES2 (Engineering Sample 2) version of the board]
Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net>

---
Changes v3 -> v4:
 - specify an explicit ATF version in the defconfig and use 1.5
   (Thomas)
 - update readme.txt

Changes v2 -> v3:
 - adapt to changed ATF option name
   (BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL31_UBOOT)
 - adapt to the new pmufw implementation in uboot (no
   zynqmp-pmufw-binaries package, just a downloadable file)
 - patches now upstream, update patch files

Changes v1 -> v2:
 - don't provide psu_init files: the xilinx master branch has a
   defconfig that works (with 2 patches)

+Subject: [PATCH 1/2] arm64: zynqmp: zcu106: fix SPL MMC booting
+
+The U-Boot SPL generated with the current zcu106 defconfig cannot boot
+from MMC:
+
+  [...]
+  U-Boot SPL 2018.01 (Feb 21 2018 - 17:47:14)
+  EL Level:  EL3
+  Trying to boot from MMC1
+  sdhci_transfer_data: Error detected in status(0x408020)!
+  spl_load_image_fat_os: error reading image u-boot.bin, err - -2
+  spl_load_image_fat: error reading image u-boot.img, err - -6
+  SPL: failed to boot from all boot devices
+  ### ERROR ### Please RESET the board ###
+
+Fix by lowering the rpll value. The new value for the RPLL_CTRL
+register comes from the current psu_init_gpl.c from the HDF file at
+https://github.com/xilinx/hdf-examples/tree/01ad8ea5fd1989abf4ea5a072d019a16cb2bc546/zcu106-zynqmp
+(generated by Vivado v2017.4).
+
+RPLL and sdio1_ref clocks before and after this change:
+
+ - Old values: RPLL 1.36 GHz, sdio1_ref 272 MHz
+ - New values: RPLL 1.16 GHz, sdio1_ref 233 MHz

+Subject: [PATCH] arm64: zynqmp: Enable booting to ATF
+
+U-Boot is now able to boot to ARM Trusted Firmware (ATF). The boot
+flow is SPL(EL3) loads ATF and full u-boot and jump to ATF(EL3) which
+pass control to full u-boot(EL2). This has been tested on zcu106, so
+enable it in this defconfig.
+
+To generate an image that triggers this booting flow, you need to pass
+'-O arm-trusted-firmware' to mkimage.

+********************************
+Xilinx ZCU106 board - ZynqMP SoC
+********************************
+
+This document describes the Buildroot support for the ZCU106 board by
+Xilinx, based on the Zynq UltraScale+ MPSoC (aka ZynqMP). It has been
+tested with the EK-U1-ZCU106-ES2 pre-production board.
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make zynqmp_zcu106_defconfig
+
+Compile everything and build the rootfs image:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+    output/images/
+    +-- atf-uboot.ub
+    +-- bl31.bin
+    +-- boot.bin
+    +-- boot.vfat
+    +-- Image
+    +-- rootfs.ext2
+    +-- rootfs.ext4 -> rootfs.ext2
+    +-- sdcard.img
+    +-- system.dtb -> zynqmp-zcu106-revA.dtb
+    +-- u-boot.bin
+    `-- zynqmp-zcu106-revA.dtb
+
+How to write the SD card
+========================
+
+WARNING! This will destroy all the card content. Use with care!
+
+The sdcard.img file is a complete bootable image ready to be written
+on the boot medium. To install it, simply copy the image to an SD
+card:
+
+    # dd if=output/images/sdcard.img of=/dev/sdX
+
+Where 'sdX' is the device node of the SD.
+
+Eject the SD card, insert it in the board, and power it up.
