A common mistake when writing a device tree for a platform that is using
GICv3 with ancient CPUs is to overlook the MMIO frames that implement
the GICv2 compatibility feature, because this feature is implemented by
the CPUs and not by the GIC itself.
The compatibility feature itself is optional (all the modern
implementations have dropped it), but is present in all the ARM Ltd
implementations of the ARMv8.0 architecture (A3x, A53, A57, A72, A73),
and many others from various implementers.
Make it explicit that GICC, GICH and GICV are required for these CPUs.
Also take this opportunity to update my email address, as people keep

Recent work on the KVM GIC emulation has revealed that the GICv3
driver is a bit RWP-happy, as it polls this bit for each and
every write MMIO access involving a single interrupt.
As it turns out, polling RWP is only required when:
- Disabling an SGI, PPI or SPI
- Disabling LPIs at the redistributor level
- Disabling groups
- Enabling ARE
- Dealing with DPG*
Simplify the driver by removing all the other instances of RWP
polling, and add the one that was missing when enabling the distributor
(as that's where we set ARE).

Since GICv4.1, an implementation can offer the same MMIO-based
implementation as DirectLPI, only with an ITS. Given that this
can be hugely beneficial for workloads that are very LPI masking
heavy (although these workloads are admitedly a bit odd).
Interestingly, this is independent of RVPEI, which only *implies*
the functionnality.
So let's detect whether the implementation has GICR_CTLR.IR set,
and propagate this as DirectLPI to the ITS driver.
While we're at it, repaint the GICv3 banner so that we advertise
the various capabilities at boot time to be slightly less invasive.

Only the main IPC ops struct should be visible outside of IPC3 code to make
sure that the code is correctly abstracted.
Instead of keeping the ipc3-ops.h with only the high level ops struct
declaration, put the ipc3_ops to sof-priv.h and move all other ops struct
declaration into ipc3-priv.h
New IPC implementation should follow this route: the main IPC ops should be
declared in sof-priv.h and no other IPC version related header be used
for generic code.

The arm64 kernel requires some metadata for each system register it may
need to access. Currently we have:
* A SYS_<regname> definition which sorresponds to a sys_reg() macro.
This is used both to look up a sysreg by encoding (e.g. in KVM), and
also to generate code to access a sysreg where the assembler is
unaware of the specific sysreg encoding.
Where assemblers support the S3_<op1>_C<crn>_C<crm>_<op2> syntax for
system registers, we could use this rather than manually assembling
the instructions. However, we don't have consistent definitions for
these and we currently still need to handle toolchains that lack this
feature.
* A set of <regname>_<fieldname>_SHIFT and <regname>_<fieldname>_MASK
definitions, which can be used to extract fields from the register, or
to construct a register from a set of fields.
These do not follow the convention used by <linux/bitfield.h>, and the
masks are not shifted into place, preventing their use in FIELD_PREP()
and FIELD_GET(). We require the SHIFT definitions for inline assembly
(and WIDTH definitions would be helpful for UBFX/SBFX), so we cannot
only define a shifted MASK. Defining a SHIFT, WIDTH, shifted MASK and
unshifted MASK is tedious and error-prone and life is much easier when
they can be relied up to exist when writing code.
* A set of <regname>_<fieldname>_<valname> definitions for each
enumerated value a field may hold. These are used when identifying the
presence of features.
Atop of this, other code has to build up metadata at runtime (e.g. the
sets of RES0/RES1 bits in a register).
This patch adds scripting so that we can have an easier-to-manage
canonical representation of this metadata, from which we can generate
all the definitions necessary for various use-cases, e.g.
| #define REG_ID_AA64ISAR0_EL1 S3_0_C0_C6_0
| #define SYS_ID_AA64ISAR0_EL1 sys_reg(3, 0, 0, 6, 0)
| #define SYS_ID_AA64ISAR0_EL1_Op0 3
| #define SYS_ID_AA64ISAR0_EL1_Op1 0
| #define SYS_ID_AA64ISAR0_EL1_CRn 0
| #define SYS_ID_AA64ISAR0_EL1_CRm 6
| #define SYS_ID_AA64ISAR0_EL1_Op2 0
| #define ID_AA64ISAR0_EL1_RNDR GENMASK(63, 60)
| #define ID_AA64ISAR0_EL1_RNDR_MASK GENMASK(63, 60)
| #define ID_AA64ISAR0_EL1_RNDR_SHIFT 60
| #define ID_AA64ISAR0_EL1_RNDR_WIDTH 4
| #define ID_AA64ISAR0_EL1_RNDR_NI UL(0b0000)
| #define ID_AA64ISAR0_EL1_RNDR_IMP UL(0b0001)
The script requires that all bits in the register be specified and that
there be no overlapping fields. This helps the script spot errors in the
input but means that the few registers which change layout at runtime
depending on things like virtualisation settings will need some manual
handling. No actual register conversions are done here but a header for
the register data with some documention of the format is provided.
For cases where multiple registers share a layout (eg, when identical
controls are provided at multiple ELs) the register fields can be
defined once and referenced from the actual registers, currently we do
not generate actual defines for the individual registers.
At the moment this is only intended to express metadata from the
architecture, and does not handle policy imposed by the kernel, such as
values exposed to userspace or VMs. In future this could be extended to
express such information.
This script was mostly written by Mark Rutland but has been extended by
Mark Brown to improve validation of input and better integrate with the
kernel.

In preparation for automatic generation of the defines for system registers
make the values used for the enumeration in SCTLR_ELx.TCF suitable for use
with the newly defined SYS_FIELD_PREP_ENUM helper, removing the shift from
the define and using the helper to generate it on use instead. Since we
only ever interact with this field in EL1 and in preparation for generation
of the defines also rename from SCTLR_ELx to SCTLR_EL1. SCTLR_EL2 is not
quite the same as SCTLR_EL1 so the conversion does not share the field
definitions.

The macros we define for the bitfields within sysregs have very regular
names, especially once we switch to automatic generation of those macros.
Take advantage of this to define wrappers around FIELD_PREP() allowing
us to simplify setting values in fields either numerically
SYS_FIELD_PREP(SCTLR_EL1, TCF0, 0x0)
or using the values of enumerations within the fields
SYS_FIELD_PREP_ENUM(SCTLR_EL1, TCF0, ASYMM)
