544cd2ac13 ice: Add AdminQ commands for FW update
Add structures, identifiers, and helper functions for several AdminQ
commands related to performing a firmware update for the ice hardware.
These will be used in future code for implementing the devlink
.flash_update handler.

ea78ce4dab ice: add link lenient and default override support
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.

f45a645fa6 ice: report netlist version in .info_get
The flash memory for the ice hardware contains a block of information
used for link management called the Netlist module.

As this essentially represents another section of firmware, add its
version information to the output of the driver's .info_get handler.

This includes both a version and the first few bytes of a hash of the
module contents.

  fw.netlist -> the version information extracted from the netlist module
  fw.netlist.build-> first 4 bytes of the hash of the contents, similar
                     to fw.mgmt.build

84a2479822 ice: implement full NVM read from ETHTOOL_GEEPROM
The current implementation of .get_eeprom only enables reading from the
Shadow RAM portion of the NVM contents. Implement support for reading
the entire flash contents instead of only the initial portion contained
in the Shadow RAM.

A complete dump can take several seconds, but the ETHTOOL_GEEPROM ioctl
is capable of reading only a limited portion at a time by specifying the
offset and length to read.

In order to perform the reads directly, several functions are made non
static. Additionally, the unused ice_read_sr_buf_aq and ice_read_sr_buf
functions are removed.

81f07491e2 ice: discover and store size of available flash
When reading from the NVM using a flat address, it is useful to know the
upper bound on the size of the flash contents. This value is not stored
within the NVM.

We can determine the size by performing a bisection between upper and
lower bounds. It is known that the size cannot exceed 16 MB (offset of
0xFFFFFF).

Use a while loop to bisect the upper and lower bounds by reading one
byte at a time. On a failed read, lower the maximum bound. On
a successful read, increase the lower bound.

Save this as the flash_size in the ice_nvm_info structure that contains
data related to the NVM.

The size will be used in a future patch for implementing full NVM read
via ethtool's GEEPROM command.

The maximum possible size for the flash is bounded by the size limit for
the NVM AdminQ commands. Add a new macro, ICE_AQC_NVM_MAX_OFFSET, which
can be used to represent this upper bound.

d4e874448e ice: store NVM version info in extracted format
The NVM version and Option ROM version information is stored within the
struct ice_nvm_ver_info structure. The data for the NVM is stored as
a 2byte value with the major and minor versions each using one byte from
the field. The Option ROM is stored as a 4byte value that contains
a major, build, and patch number.

Modify the code to immediately extract the version values and store them
in a new struct ice_orom_info. Remove the now unnecessary
ice_get_nvm_version function.

Update ice_ethtool.c to use the new fields directly from the structured
data.

This reduces complexity of the code that prints these versions in
ice_ethtool.c

Update the macro definitions and variable names to use the term "orom"
instead of "oem" for the Option ROM version. This helps increase the
clarity of the Option ROM version code.

e94509906d ice: create function to read a section of the NVM and Shadow RAM
The NVM contents are read via firmware by using the ice_aq_read_nvm
function. This function has a couple of limits:

1) The AdminQ commands can only take buffers sized up to 4Kb. Thus, any
   larger read must be split into multiple reads.
2) when reading from the Shadow RAM, reads must not cross sector
   boundaries. The sectors are also 4Kb in size.

Implement the ice_read_flat_nvm function to read portions of the NVM by
flat offset. That is, to read using offsets from the start of the NVM
rather than from a specific module.

This function will be able to read both from the NVM and from the Shadow
RAM. For simplicity NVM reads will always be broken up to not cross 4Kb
page boundaries, even though this is not required unless reading from
the Shadow RAM.

Use this new function as the implementation of ice_read_sr_word_aq.

The ice_read_sr_buf_aq function is not modified here. This is because
a following change will remove the only caller of that function in favor
of directly using ice_read_flat_nvm. Thus, there is little benefit to
changing it now only to remove it momentarily. At the same time, the
ice_read_sr_aq function will also be removed.

2efefb56f9 ice: use __le16 types for explicitly Little Endian values
The ice_read_sr_aq function returns words in the Little Endian format.
Remove the need for __force and typecasting by using a local variable in
the ice_read_sr_word_aq function.

Additionally clarify explicitly that the ice_read_sr_aq function takes
storage for __le16 values instead of using u16.

Being explicit about the endianness of this data helps when using tools
like sparse to catch endian-related issues.

4c98ab550c ice: Implement support for normal get_eeprom[_len] ethtool ops
Add support for get_eeprom and get_eeprom_len ethtool ops

Specification states that PF software accesses NVM (shadow-ram) via AQ
commands (e.g. NVM Read, NVM Write) in the range 0x000000-0x00FFFF (64KB),
so the get_eeprom_len op should return 64KB.  If additional regions of the
16MB NVM must be read, another access method must be used.

The ethtool kernel code, by default, will ask for multiple page-size hunks
of the NVM not to exceed the value returned by ice_get_eeprom_len().
ice_read_sr_buf() deals with arch page sizes different than 4KB.
