2019-10-08firmware: zynqmp: Add zynqmp-power supportIbai Erkiaga
zynqmp-power driver for ZynqMP to handle the communication with the PMU firmware. Firmware driver just probes subnodes and power driver handles communication with PMU using the IPI mailbox driver.

2019-10-08microblaze: Remove additional headersMichal Simek
There were several changes in past in this file without removing headers (watchdog cleanup, soft reset, etc). That's why remove additional useless headers. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2019-10-08microblaze: Setup initrd_high and fdt_high at run timeMichal Simek
Setup initrd_high and fdt_high to be placed in lowmem space for kernel to be able to reach it. Values are setup at run time to ensure that the same setting can be used on different memory setup. Do this setting only when variables are not Similar run time detection was done for Zynqmp and Versal. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2019-10-08microblaze: Setup reasonable maximum bootm lenMichal Simek

2019-10-08microblaze: Enable cache by defaultMichal Simek
The whole cache code needs to be redesign to read information about cache from DT instead of macro selection. Enable caches by default because systems have caches on by default for Linux. Also enable CMD_CACHE to be able to disable cache if there is any issue. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2019-10-08microblaze: Switch to generic bootm implementationMichal Simek
There is no reason to use private code for standard bootm command. Current implementation is also broken and don't support image relocation properly. Switching to generic bootm implementation is fixing these issues. cmdline and bdt bootm subcommands are returning -1 because they are not implemented. Similar change was done long time ago by for example commit 2bb5b638791d ("MIPS: bootm: rework and fix broken bootm code") Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2019-10-08arm64: zynqmp: Add System Controller for a2197-g/pMichal Simek
Similar SCs but different wiring. - dc_i2c is connected to X-PRC cards that's why label is required to have an option to hook up some devices. - Exactly identify i2c devices on x-prc boards. In case of missing i2c connection devices won't be accessible. - USB 0 should be device mode with super speed. - USB 1 should be host mode. - Fix i2c mux reset pin entry - commented, not verified. - Fix i2c1 eeprom compatible string - it is an ST 128Kbit device. Need to use atmel fallback. - Fix si570 I2C slave address and add corresponding part numbers. - Enable AMS for system monitoring. - phy reset property should be commented because it will throw a warning dump when called from context that can sleep. No support for phys property (zynqmp phy driver) with SGMII. Add is-internal-pcspma property required by uboot.
