2018-07-19xilinx: zynq: Add support to secure imagesSiva Durga Prasad Paladugu
This patch basically adds two new commands for loadig secure images. 1. zynq rsa adds support to load secure image which can be both authenticated or encrypted or both authenticated and encrypted image in xilinx bootimage(BOOT.bin) format. 2. zynq aes command adds support to decrypt and load encrypted image back to DDR as per destination address. The image has to be encrypted using xilinx bootgen tool and to get only the encrypted image from tool use -split option while invoking bootgen.

2018-07-19serial: zynq: Use platdata for storing static data instead of privMichal Simek
Explanation from Simon Glass "Private data is created when the device is probed and freed when the device is removed. Platform data is created when the device is bound, and survives probe/remove cycles. Strictly speaking, platform data should be used to hold the decoded device tree properties. Private data should be used for run-time things the device needs to keep track of." Based on description the driver needs to be switch to use platdata instead of priv.

2018-07-19arm/arm64: zynq/zynqmp: pass the PS init file as a kconfig variableLuca Ceresoli
U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on ZynqMP (PS init for short). The current logic to locate this file for both platforms is: 1. if a board-specific file exists in board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c then use it 2. otherwise use board/xilinx/zynq/ps?_init_gpl.c In the latter case the file does not exist in the U-Boot sources and must be copied in the source tree from the outside before starting the build. This is typical when it is generated from Xilinx tools while developing a custom hardware. However making sure that a board-specific file is _not_ found (and used) requires some trickery such as removing or overwriting all PS init files (e.g.: the current meta-xilinx yocto layer). This generates a few problems: * if the source tree is shared among different out-of-tree builds, they will pollute (and potentially corrupt) each other * the source tree cannot be read-only * any buildsystem must add a command to copy the PS init file binary * overwriting or deleting files in the source tree is ugly as hell Simplify usage by allowing to pass the path to the desired PS init file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute path or relative to $(srctree). If the variable is set, the user-specified file will always be used without being copied around. If the the variable is left empty, for backward compatibility fall back to the old behaviour. Since the issue is the same for Zynq and ZynqMP, add one kconfig variable in a common place and use it for both. Also use the new kconfig help text to document all the ways to give U-Boot the PS init file. Build-tested with all combinations of: - platform: zynq or zynqmp - PS init file: from XILINX_PS_INIT_FILE (absolute, relative path, non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/ - building in-tree, in subdir, in other directory Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net> Cc: Albert Aribaud <albert.u.boot@aribaud.net> Cc: Michal Simek <michal.simek@xilinx.com> Cc: Nathan Rossi <nathan@nathanrossi.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2018-07-19common: command: Handle USAGE failure separatelyMichal Simek
command_ret_t enum contains 3 return values but only two are handled now. Extend cmd_process_error() and handle CMD_RET_USAGE separately. These commands are affected by this change. cmd/demo.c cmd/efi.c cmd/gpio.c cmd/qfw.c cmd/x86/fsp.c test/dm/cmd_dm.c And scripts shouldn't be affected because return value is not 0. But every command implementation can choose what it is correct to pass. I would expect that RET_USAGE is called when parameters are not correctly passed (have incorrect value, missing parameters) and RET_FAILURE when correct parameters are passed but command fails.

2018-07-17sunxi: Enable eMMC on Libre Computer Board ALL-H3-CC boardsChen-Yu Tsai
The Libretech ALL-H3-CC has a high density connector for attaching an eMMC module. The module form factor and connection is specific to Libretech, and has provisions for split vmmc/vqmmc (core and I/O) voltage supplies, but this board does not wire the vqmmc side. The H2+/H3/H5 SoCs do not support alternate I/O voltages for eMMC either. Only 3.3V is supported. A specific module that ties vqmmc to vmmc, with both at 3.3V, must be used. Given that a) eMMC is not designed to be hotplugged, b) power is always provided on the pins, and c) MMC controllers can deal with missing cards, we can enable this by default. If a module is attached it will be picked up by the system. The device tree change was also submitted to the Linux Kernel and has already been queued up for 4.19.
