ppc/vof: Fix Coverity issues
Coverity reported issues which are caused by mixing of signed return codes from DTC and unsigned return codes of the client interface.
This introduces PROM_ERROR and makes distinction between the error types.
This fixes NEGATIVE_RETURNS, OVERRUN issues reported by Coverity.
This adds a comment about the return parameters number in the VOF hcall. The reason for such counting is to keep the numbers look the same in vof_client_handle() and the Linux (an OF client).
vmc->client_architecture_support() returns target_ulong and we want to propagate this to the client (for example H_MULTI_THREADS_ACTIVE). The VOF path to do_client_architecture_support() needs chopping off the top 32bit but SLOF's H_CAS does not; and either way the return values are either 0 or 32bit negative error code. For now this chops the top 32bits.
This makes "claim" fail if the allocated address is above 4GB as the client interface is 32bit. This still allows claiming memory above 4GB as potentially initrd can be put there and the client can read the address from the FDT's "available" property.

Merge remote-tracking branch 'remotes/dg-gitlab/tags/ppc-for-6.1-20210709' into staging
ppc patch queue 2021-07-09
Here's a (probably) final pull request before the qemu-6.1 soft freeze. Includes: * Implementation of the new H_RPT_INVALIDATE hypercall * Virtual Open Firmware for pSeries and pegasos2 machine types. This is an experimental minimal Open Firmware implementation which works by delegating nearly everything to qemu itself via a special hypercall. * A number of cleanups to the ppc soft MMU code * Fix to handling of two-level radix mode translations for the powernv machine type * Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits. This will allow more flexible handling of possible future CPU Spectre-like flaws * Correctly treat mtmsrd as an illegal instruction on BookE cpus * Firmware update for the ppce500 machine type

spapr: Fix implementation of Open Firmware client interface
This addresses the comments from v22.
The functional changes are (the VOF ones need retesting with Pegasos2):
(VOF) setprop will start failing if the machine class callback did not handle it; (VOF) unit addresses are lowered in path_offset(); (SPAPR) /chosen/bootargs is initialized from kernel_cmdline if the client did not change it.

spapr: Implement Open Firmware client interface
The PAPR platform describes an OS environment that's presented by a combination of a hypervisor and firmware. The features it specifies require collaboration between the firmware and the hypervisor.
Since the beginning, the runtime component of the firmware (RTAS) has been implemented as a 20 byte shim which simply forwards it to a hypercall implemented in qemu. The boot time firmware component is SLOF - but a build that's specific to qemu, and has always needed to be updated in sync with it. Even though we've managed to limit the amount of runtime communication we need between qemu and SLOF, there's some, and it has become increasingly awkward to handle as we've implemented new features.
This implements a boot time OF client interface (CI) which is enabled by a new "x-vof" pseries machine option (stands for "Virtual Open Firmware). When enabled, QEMU implements the custom H_OF_CLIENT hcall which implements Open Firmware Client Interface (OF CI). This allows using a smaller stateless firmware which does not have to manage the device tree.
The new "vof.bin" firmware image is included with source code under pc-bios/. It also includes RTAS blob.
This implements a handful of CI methods just to get -kernel/-initrd working. In particular, this implements the device tree fetching and simple memory allocator - "claim" (an OF CI memory allocator) and updates "/memory@0/available" to report the client about available memory.
This implements changing some device tree properties which we know how to deal with, the rest is ignored. To allow changes, this skips fdt_pack() when x-vof=on as not packing the blob leaves some room for appending.
In absence of SLOF, this assigns phandles to device tree nodes to make device tree traversing work.
When x-vof=on, this adds "/chosen" every time QEMU (re)builds a tree.
This adds basic instances support which are managed by a hash map ihandle -> [phandle].
Before the guest started, the used memory is: 0..e60 - the initial firmware 8000..10000 - stack 400000.. - kernel 3ea0000.. - initramdisk
This OF CI does not implement "interpret".
Unlike SLOF, this does not format uninitialized nvram. Instead, this includes a disk image with pre-formatted nvram.
With this basic support, this can only boot into kernel directly. However this is just enough for the petitboot kernel and initradmdisk to boot from any possible source. Note this requires reasonably recent guest kernel with: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=df5be5be8735
The immediate benefit is much faster booting time which especially crucial with fully emulated early CPU bring up environments. Also this may come handy when/if GRUB-in-the-userspace sees light of the day.
This separates VOF and sPAPR in a hope that VOF bits may be reused by other POWERPC boards which do not support pSeries.
This assumes potential support for booting from QEMU backends such as blockdev or netdev without devices/drivers used.
