Since commit 502df79b86 ("gpiolib: Warn on drivers still using
static gpiobase allocation") in gpio/for-next, one or more warnings are
printed during boot on systems where the pin controller also provides
GPIO functionality:
gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.
Fix this for ARM-based SH/R-Mobile SoCs by:
1. Taking into account a non-zero GPIO base in the various GPIO chip
callbacks,
2. Switching to dynamic allocation of the GPIO base when support for
legacy function GPIOs is not enabled.
On SuperH SoCs using legacy function GPIOs, the GPIO bases of the GPIO
controller and the GPIO function controller must not be changed, as all
board files rely on the fixed GPIO_* and GPIO_FN_* definitions provided
by the various <cpu/sh*.h> header files.

Attestation is used to verify the trustworthiness of a TDX guest.
During the guest bring-up, the Intel TDX module measures and records
the initial contents and configuration of the guest, and at runtime,
guest software uses runtime measurement registers (RMTRs) to measure
and record details related to kernel image, command line params, ACPI
tables, initrd, etc. At guest runtime, the attestation process is used
to attest to these measurements.
The first step in the TDX attestation process is to get the TDREPORT
data. It is a fixed size data structure generated by the TDX module
which includes the above mentioned measurements data, a MAC ID to
protect the integrity of the TDREPORT, and a 64-Byte of user specified
data passed during TDREPORT request which can uniquely identify the
TDREPORT.
Intel's TDX guest driver exposes TDX_CMD_GET_REPORT0 IOCTL interface to
enable guest userspace to get the TDREPORT subtype 0.
Add a kernel self test module to test this ABI and verify the validity
of the generated TDREPORT.

TDX guest driver exposes IOCTL interfaces to service TDX guest
user-specific requests. Currently, it is only used to allow the user to
get the TDREPORT to support TDX attestation.
Details about the TDX attestation process are documented in
Documentation/x86/tdx.rst, and the IOCTL details are documented in
Documentation/virt/coco/tdx-guest.rst.
Operations like getting TDREPORT involves sending a blob of data as
input and getting another blob of data as output. It was considered
to use a sysfs interface for this, but it doesn't fit well into the
standard sysfs model for configuring values. It would be possible to
do read/write on files, but it would need multiple file descriptors,
which would be somewhat messy. IOCTLs seem to be the best fitting
and simplest model for this use case. The AMD sev-guest driver also
uses the IOCTL interface to support attestation.

To support TDX attestation, the TDX guest driver exposes an IOCTL
interface to allow userspace to get the TDREPORT0 (a.k.a. TDREPORT
subtype 0) from the TDX module via TDG.MR.TDREPORT TDCALL.
In order to get the TDREPORT0 in the TDX guest driver, instead of using
a low level function like __tdx_module_call(), add a
tdx_mcall_get_report0() wrapper function to handle it.
This is a preparatory patch for adding attestation support.

If the hangcheck timer expires, check if the fw's position in the

allow it up to three additional "extensions" to it's alotted time.
The intention is to continue to catch "shader stuck in a loop" type
hangs quickly, but allow more time for things that are actually
making forward progress.
Because we need to sample the CP state twice to detect if there has
not been progress, this also cuts the the timer's duration in half.
v2: Fix typo (REG_A6XX_CP_CSQ_IB2_STAT), add comment
v3: Only halve hangcheck timer duration for generations which
