4a9bd6db19 drm/amd/pm: And destination bounds checking to struct copy
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.

The "Board Parameters" members of the structs:
	struct atom_smc_dpm_info_v4_5
	struct atom_smc_dpm_info_v4_6
	struct atom_smc_dpm_info_v4_7
	struct atom_smc_dpm_info_v4_10
are written to the corresponding members of the corresponding PPTable_t
variables, but they lack destination size bounds checking, which means
the compiler cannot verify at compile time that this is an intended and
safe memcpy().

Since the header files are effectively immutable[1] and a struct_group()
cannot be used, nor a common struct referenced by both sides of the
memcpy() arguments, add a new helper, amdgpu_memcpy_trailing(), to
perform the bounds checking at compile time. Replace the open-coded
memcpy()s with amdgpu_memcpy_trailing() which includes enough context
for the bounds checking.

"objdump -d" shows no object code changes.

8ac1696b1d drm/amd/pm: a quick fix for "divided by zero" error
Considering Arcturus is a dedicated ASIC for computing, it
will be more proper to drop the support for fan speed reading
and setting. That's on the TODO list.

0d8318e112 drm/amd/pm: drop the unnecessary intermediate percent-based transition
Currently, the readout of fan speed pwm is transited into percent-based
and then pwm-based. However, the transition into percent-based is totally
unnecessary and make the final output less accurate.

d9ca7567b8 drm/amd/pm: correct the fan speed RPM retrieving
The relationship "PWM = RPM / smu->fan_max_rpm" between fan speed
PWM and RPM is not true for SMU11 ASICs. So, we need a new way to
retrieving the fan speed RPM.

c0838d3a93 drm/amdgpu: The I2C IP doesn't support 0 writes/reads
The I2C IP doesn't support writes or reads of 0 bytes.

In order for a START/STOP transaction to take
place on the bus, the data written/read has to be
at least one byte.

That is, you cannot generate a write with 0 bytes,
just to get the ACK from a device, just so you can
probe that device if it is on the bus and so to
discover all devices on the bus--you'll have to
read at least one byte. Writes of 0 bytes generate
no START/STOP on this I2C IP--the bus is not
engaged at all.

Set the I2C_AQ_NO_ZERO_LEN to the existing I2C
quirk tables for Aldebaran, Arcturus, Navi10 and
Sienna Cichlid, and add a quirk table to the I2C
driver which drives the bus when the SMU
doesn't--for instance on Vega20.

ebe57d0c8e drm/amd/pm: Simplify managed I2C transfer functions
Now that we have an I2C quirk table for
SMU-managed I2C controllers, the I2C core does the
checks for us, so we don't need to do them, and so
simplify the managed I2C transfer functions.

Also, for Arcturus and Navi10, fix setting the
command type from "cmd->CmdConfig" to "cmd->Cmd".
The latter is what appears to be taking in
the enumeration I2C_CMD_... as an integer,
not a bit-flag.

For Sienna, the "Cmd" field seems to have been
eliminated, and command type and flags all live in
the "CmdConfig" field--this is left untouched.

Fix: Detect and add changing of direction
bit-flag, as this is necessary for the SMU to
detect the direction change in the 1-d array of
data it gets.
