+Subject: [PATCH] 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.
