When there is a timeout for an i2c transaction, the i2c driver should do
the recovery logic to make the bus and driver state machine go back to
idle. Otherwise, it will cause the following transaction to fail because
the state machine keeps in an inappropriate state.

Executing code out of RAM on IT8xxx2 requires that the relevant
addresses be mapped onto the CPU's instruction memory bus, referred to
by ITE documentation as Instruction Local Memory (ILM). ILM mappings
configure blocks of RAM to be used for accesses to chosen addresses when
performing instruction fetch, instead of the memory that would normally
be accessed at that address.
ILM must be used for some chip features (particularly Flash
self-programming, to execute from RAM while writing to Flash), and has
historically been configured in the Flash driver. The RAM for that was
hard-coded as a single 4k block in the linker script. Configuring ILM
in the flash driver is confusing because it is used by other SoC code as
well, currently in code that cannot depend on the Flash being functional
or in hand-selected functions that seem performance-critical.
This change moves ILM configuration to a new driver and dynamically
allocates RAM to ILM in the linker script, allowing software use of the
entire 64k RAM depending on configuration. This makes ILM configuration
more discoverable and makes it much easier to correctly support the
CODE_DATA_RELOCATION feature on this SoC.

eSPI PUT_IOWR_SHORT protocol can send 1/2/4 bytes of data in a single
transaction. This allows the host to send max 32-bits Port80 code
at one time. This CL sets bits OFS0_SEL~OFS3_SEL in the DPAR1 register
to let the EC hardware put the full Port80 code to DP80BUF FIFO.
It also groups the N-byte code into a single 32-bits variable when
necessary by analyzing the offset field in the DP80BUF register.

The TXF interrupt mask is not properly set. In this case the

the issue is linked to the management of the IPCC_CxTOCySR value.
The TXF interrupt is triggered when the IPCC_CyMR is channel bit is
set to 0 and the IPCC_CxTOCySR associated bit move from 1 to 0.
The fix is to check if the IPCC_CxTOCySR channel bit is 0 instead of 1.

disregarded within the Linux kernel. It is just there for being able to
reuse the canfd_frame struct for classic CAN frames in Linux user-space
applications.
Define the CANFD_FDF flag locally if not already defined to allow compiling
against older Linux kernel headers.

This change implements part two of the program laid out in the TSCH RFC,
see #50336#issuecomment-1250250154 :
> Consolidate IEEE 802.15.4 options in net_pkt
This change improves decoupling of generic net core code from
IEEE 802.15.4 internals. It also simplifies IEEE 802.15.4
attribute cloning and thereby makes it easier to maintain and less
error prone (and probably even faster as individual bits are no longer
copied over separately).
This enables us to extend and design IEEE 802.15.4 L2 attributes inside
the package in isolation from the net core code which will no longer
have to be changed when introducing changes or additions to the flags.
This flexibility will be built upon in later change sets to model the
IEEE 802.15.4 attributes closer to the spec.
The solution is inspired by Linux's sk_buff->cb attribute which addresses
the same concern as the attribute introduced in this change set:
https://elixir.bootlin.com/linux/v6.0.1/source/include/linux/skbuff.h#L871
As the inline comment says: The cb attribute can be made a union or even a
uint8[something] in the future, if further L2s need a control block, too.
Right now such full indirection would make the code overly abstract, so
I chose to compromise with maintainability in mind.
Care has been taken to ensure that this changes does not introduce
additional padding into the net package. To maintain zero-padding, future
changes to the net packet struct will have to ensure that the
IEEE 802.15.4 struct is 4-byte aligned (iff the IEEE 802.15.4 struct
continues with max uint32_t scalar members) which is no deviation from
the previous implementation.

Nordic's IEEE 802.15.4 radio driver adapter layer had a few raw accesses
to net packet attributes.
Packet attributes should never be accessed directly, though, but only
through the dedicated accessor methods provided by the net core.
This change replaces raw accesses to packet attributes by their
respective wrapper functions.
This also is a necessary precondition to the isolation and
encapsulation of IEEE 802.15.4 specific packet attributes which will be
introduced in a later commit of this change set.

Several IEEE 802154 drivers allocated RX packets from the TX pool.
This may seem like a minor problem at first sight but it may become
problematic if the pool is used to distinguish package types as is the
case in some code paths, e.g. for packet priority or determination of
the packet buffer pool.
This bug also has the potential of starving the TX pool capacity which
even may make devices vulnerable to DoS attacks as sending may be
prohibited by addressing enough RX packets to a device to let it run out
of TX capacity.
