2022-02-16payloads/external: add skiboot (for QEMU/Power9)Sergii Dmytruk
Add an option to build skiboot as a payload. This makes QEMU Power9 board simpler to use as skiboot is necessary anyway.

2022-02-11src/arch/ppc64/*: pass FDT address to payloadSergii Dmytruk
It's available in %r3 in bootblock and needs to be passed to payload in %r27. We use one of two hypervisor's special registers as a buffer, which aren't used for anything by the code.

2022-02-11src/mainboard/emulation/qemu-power9: require hb-mode=onYaroslav Kurlaev
"hb-mode" is a -machine flag for QEMU. "hb" stands for Hostboot, which is OpenPower firmware created by IBM. QEMU for PPC64 can run initial program in two different modes: * hb-mode=off with load address 0x00000000 * hb-mode=on with load address 0x08000000 Real hardware always loads firmware at 0x08000000 and coreboot shouldn't require a special build to be run on QEMU. Memory layout is updated to reflect change of load address.
