[WHY]
Some early Raven boards had a bad SBIOS that doesn't play nicely with
the DMCU FW. We thought the issues were fixed by ignoring errors on DMCU
load but that doesn't seem to be the case. We've still seen reports of
users unable to boot their systems at all.
[HOW]
Disable DMCU load on Raven 1. Only load it for Raven 2 and Picasso.

With Sphinx 2.0 (or prior versions with the deprecation warnings fixed) the
docs build fails with:
Documentation/gpu/i915.rst:403: WARNING: Title level inconsistent:
Global GTT Fence Handling
~~~~~~~~~~~~~~~~~~~~~~~~~
reST markup error:
Documentation/gpu/i915.rst:403: (SEVERE/4) Title level inconsistent:
I "fixed" it by changing the subsections in i915.rst, but that didn't seem
like the correct change. It turns out that a couple of i915 files create
their own subsections in kerneldoc comments using apostrophes as the
heading marker:
Layout
''''''
That breaks the normal subsection marker ordering, and newer Sphinx is
rather more strict about enforcing that ordering. So fix the offending
comments to make Sphinx happy.
(This is unfortunate, in that kerneldoc comments shouldn't need to be aware
of where they might be included in the heading hierarchy, but I don't see
a better way around it).

After memory allocation failure vc_allocate() doesn't clean up data
which has been initialized in visual_init(). In case of fbcon this
leads to divide-by-0 in fbcon_init() on next open of the same tty.
memory allocation in vc_allocate() may fail here:
1097: vc->vc_screenbuf = kzalloc(vc->vc_screenbuf_size, GFP_KERNEL);
on next open() fbcon_init() skips vc_font.data initialization:

GCC 8.1.0 reports that the ldadd instruction encoding, recently added to
insn.c, doesn't match the mask and couldn't possibly be identified:
linux/arch/arm64/include/asm/insn.h: In function 'aarch64_insn_is_ldadd':
linux/arch/arm64/include/asm/insn.h:280:257: warning: bitwise comparison always evaluates to false [-Wtautological-compare]
Bits [31:30] normally encode the size of the instruction (1 to 8 bytes)
and the current instruction value only encodes the 4- and 8-byte
variants. At the moment only the BPF JIT needs this instruction, and
doesn't require the 1- and 2-byte variants, but to be consistent with
our other ldr and str instruction encodings, clear the size field in the
insn value.

Although we merged support for pseudo-nmi using interrupt priority
masking in 5.1, we've since uncovered a number of non-trivial issues
with the implementation. Although there are patches pending to address
these problems, we're facing issues that prevent us from merging them at
this current time:
https://lkml.kernel.org/r/1556553607-46531-1-git-send-email-julien.thierry@arm.com
For now, simply mark this optional feature as BROKEN in the hope that we
can fix things properly in the near future.

KVM has helpers to handle the condition codes of trapped aarch32
instructions. These are marked __hyp_text and used from HYP, but they
aren't built by the 'hyp' Makefile, which has all the runes to avoid ASAN
and KCOV instrumentation.
Move this code to a new hyp/aarch32.c to avoid a hyp-panic when starting
an aarch32 guest on a host built with the ASAN/KCOV debug options.

After memory allocation failure vc_allocate() doesn't clean up data
which has been initialized in visual_init(). In case of fbcon this
leads to divide-by-0 in fbcon_init() on next open of the same tty.
memory allocation in vc_allocate() may fail here:
1097: vc->vc_screenbuf = kzalloc(vc->vc_screenbuf_size, GFP_KERNEL);
on next open() fbcon_init() skips vc_font.data initialization:
1088: if (!p->fontdata) {
division by zero in fbcon_init() happens here:
1149: new_cols /= vc->vc_font.width;
Additional check is needed in fbcon_deinit() to prevent

1252: set_vc_hi_font(vc, false);

SMC relocation can also be activated earlier by the bootloader,
so the driver's behaviour cannot rely on selected kernel config.
When the SMC is relocated, CPM_CR_INIT_TRX cannot be used.
But the only thing CPM_CR_INIT_TRX does is to clear the
rstate and tstate registers, so this can be done manually,
even when SMC is not relocated.
