This will prevent reloading of HS FW where it's pointless, and bypass
hitting some timeouts.
Not a situation one should generally hit, but can occur with a messed
up firmware installation.

This causes us to invalidate MMU only at the level we made modifications -

Rename all structures that are used directly by firmware to have a nvfw_
prefix.
This makes it easier to identify structures that have a fixed, specific
layout. A future patch will define several more such structures, so it's
important to be consistent now.

nvkm_timer_wait_init() takes a u64 as a duration parameter, but the
expression "(m) * 1000" will be promoted only to a 32-bit integer,
if 'm' is also an integer. Changing the 1000 to 1000ULL ensures that
the expression will be 64 bits.
This change currently has no effect as there are no callers of
nvkm_msec() that exceed 2000ms.

Check for regmap_read() return code before using the read value in
following write in exynos5_switch_timing_regs(). Pass reading error
code to the callers.
This does not introduce proper error handling for such failed reads (and
obviously regmap_write() error is still ignored) because the driver
ignored this in all places. Therefor it only fixes reported issue while
matching current driver coding style:

In case a TPM2 is attached, search for a TPM2 ACPI table when trying
to get the event log from ACPI. If one is found, use it to get the
start and length of the log area. This allows non-UEFI systems, such
as SeaBIOS, to pass an event log when using a TPM2.

Recent extensions of the TPM2 ACPI table added 3 more fields
including 12 bytes of start method specific parameters and Log Area
Minimum Length (u32) and Log Area Start Address (u64). So, we define
a new structure acpi_tpm2_phy that holds these optional new fields.
The new fields allow non-UEFI systems to access the TPM2's log.
The specification that has the new fields is the following:

The size of the buffers for storing context's and sessions can vary from
arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the
maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be
enough for most use with three handles (that is how many we allow at the
moment). Parametrize the buffer size while doing this, so that it is easier
to revisit this later on if required.

Require that the TCG_PCR_EVENT2.digests.count value strictly matches the
value of TCG_EfiSpecIdEvent.numberOfAlgorithms in the event field of the
TCG_PCClientPCREvent event log header. Also require that
TCG_EfiSpecIdEvent.numberOfAlgorithms is non-zero.
The TCG PC Client Platform Firmware Profile Specification section 9.1
(Family "2.0", Level 00 Revision 1.04) states:
For each Hash algorithm enumerated in the TCG_PCClientPCREvent entry,
there SHALL be a corresponding digest in all TCG_PCR_EVENT2 structures.
Note: This includes EV_NO_ACTION events which do not extend the PCR.
Section 9.4.5.1 provides this description of
TCG_EfiSpecIdEvent.numberOfAlgorithms:
The number of Hash algorithms in the digestSizes field. This field MUST
be set to a value of 0x01 or greater.
Enforce these restrictions, as required by the above specification, in
order to better identify and ignore invalid sequences of bytes at the
end of an otherwise valid TPM2 event log. Firmware doesn't always have
the means necessary to inform the kernel of the actual event log size so
the kernel's event log parsing code should be stringent when parsing the
event log for resiliency against firmware bugs. This is true, for
example, when firmware passes the event log to the kernel via a reserved
memory region described in device tree.
POWER and some ARM systems use the "linux,sml-base" and "linux,sml-size"
device tree properties to describe the memory region used to pass the
event log from firmware to the kernel. Unfortunately, the
"linux,sml-size" property describes the size of the entire reserved
memory region rather than the size of the event long within the memory
region and the event log format does not include information describing
the size of the event log.
tpm_read_log_of(), in drivers/char/tpm/eventlog/of.c, is where the
"linux,sml-size" property is used. At the end of that function,
log->bios_event_log_end is pointing at the end of the reserved memory
region. That's typically 0x10000 bytes offset from "linux,sml-base",
depending on what's defined in the device tree source.
The firmware event log only fills a portion of those 0x10000 bytes and
the rest of the memory region should be zeroed out by firmware. Even in
the case of a properly zeroed bytes in the remainder of the memory
region, the only thing allowing the kernel's event log parser to detect
the end of the event log is the following conditional in
__calc_tpm2_event_size():
if (event_type == 0 && event_field->event_size == 0)
size = 0;
If that wasn't there, __calc_tpm2_event_size() would think that a 16
byte sequence of zeroes, following an otherwise valid event log, was
a valid event.
However, problems can occur if a single bit is set in the offset
corresponding to either the TCG_PCR_EVENT2.eventType or
TCG_PCR_EVENT2.eventSize fields, after the last valid event log entry.
This could confuse the parser into thinking that an additional entry is
present in the event log and exposing this invalid entry to userspace in
the /sys/kernel/security/tpm0/binary_bios_measurements file. Such
problems have been seen if firmware does not fully zero the memory
region upon a warm reboot.
This patch significantly raises the bar on how difficult it is for
stale/invalid memory to confuse the kernel's event log parser but
there's still, ultimately, a reliance on firmware to properly initialize
the remainder of the memory region reserved for the event log as the
parser cannot be expected to detect a stale but otherwise properly
formatted firmware event log entry.

move vrf_strict_mode and vrf_strict_mode_change to above
vrf_shared_table_handler (code move only) and wrap all of it

There isn't a case for 1G SGMII in ice_get_media_type() so add
the handling for it.
Also handle the special case where some direct attach
cables may report that they support 1G SGMII, but
that is erroneous since SGMII is supposed to be a
backplane media type (between a MAC and a PHY). If
the driver doesn't handle this special case then a
user could see the 'Port' in ethtool change from
'Direct attach Copper' to 'Backplane' when they have
forced the speed to 1G, but the cable hasn't changed.
Lastly, change ice_aq_get_phy_caps() to save the
module_type info if the function was called with
ICE_AQC_REPORT_TOPO_CAP. This call uses the media
information to populate the module_type. If no
media is present then the values in module_type
will be 0.

Adds functions to check for link override firmware support and get
the override settings for a port. The previously supported/default link
mode was strict mode.
In strict mode link is configured based on get PHY capabilities PHY types
with media.
Lenient mode is now the default link mode. In lenient mode the link is
configured based on get PHY capabilities PHY types without media. This
allows the user to configure link that the media does not report. Limit the
minimum supported link mode to 25G for devices that support 100G, and 1G
for devices that support less than 100G.
Default override is only supported in lenient mode. If default override
is supported and enabled, then default override values are used for
configuring speed and FEC. Default override provide persistent link
settings in the NVM.
