[PATCH] arm64: zynqmp: Setup multiboot register to 0
On Kria when board starts from Image A or Image B partition multiboot register is already setup to that location. When reset command is called board is issuing soft reset which start SW at already used location (offset of multiboot * 32k). But board should continue to run from multiboot offset 0 (start of QSPI) and call early bootloader every reboot that's why clear multiboot register to 0 by default to go that route all the time.
