There is an error check following the allocation of flash_buf that returns
without freeing flash_buf. It makes more sense to do the error check
before the allocation and the reordering eliminates the memory leak.

At the moment FPGA manager core loads to the device entire image
provided to fpga_mgr_load(). But it is not always whole FPGA image
buffer meant to be written to the device. In particular, .dat formatted
image for Microchip MPF contains meta info in the header that is not
meant to be written to the device. This is issue for those low level
drivers that loads data to the device with write() fpga_manager_ops
callback, since write() can be called in iterator over scatter-gather
table, not only linear image buffer. On the other hand, write_sg()
callback is provided with whole image in scatter-gather form and can
decide itself which part should be sent to the device.
Add header_size and data_size to the fpga_image_info struct, add
skip_header to the fpga_manager_ops struct and adjust fpga_mgr_write()
callers with respect to them.
* info->header_size indicates part at the beginning of image buffer
that contains some meta info. It is optional and can be 0,
initialized with mops->initial_header_size.
* mops->skip_header tells fpga-mgr core whether write should start
from the beginning of image buffer or at the offset of header_size.
* info->data_size is the size of bitstream data that is meant to be
written to the device. It is also optional and can be 0, which
means bitstream data is up to the end of image buffer.
Also add parse_header() callback to fpga_manager_ops, which purpose is
to set info->header_size and info->data_size. At least
initial_header_size bytes of image buffer will be passed into
parse_header() first time. If it is not enough, parse_header() should
set desired size into info->header_size and return -EAGAIN, then it will
be called again with greater part of image buffer on the input.

Extend the MAX10 BMC Secure Update driver to provide sysfs files to
expose the 128 bit code signing key (CSK) cancellation vectors. These use
the standard bitmap list format (e.g. 1,2-6,9).
Each CSK is assigned an ID, a number between 0-127, during the signing
process. CSK ID cancellation information is stored in 128-bit fields in
write-once locations in flash. The cancellation of a CSK can be used
to prevent the card from being rolled back to older images that were
signed with a CSK that is now cancelled.

Create a sub-driver for the FPGA Card BMC in order to support secure
updates. This patch creates the Max10 BMC Secure Update driver and
provides sysfs files for displaying the root entry hashes (REH) for the
FPGA static region (SR), the FPGA Partial Reconfiguration (PR) region,
and the card BMC.
The Intel MAX10 BMC Root of Trust (RoT) requires that all BMC Nios firmware
and FPGA images are authenticated using ECDSA before loading and executing
on the card. Code Signing Keys (CSK) are used to sign images. CSKs are
signed by a root key. The root entry hash is created from the root public
key.
The RoT provides authentication by storing an REH bitstream to a write-once
location. Image signatures are verified against the hash.

In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.
Some reasons why this API should be removed have been given by Julia
Lawall in [2].
A coccinelle script has been used to perform the needed transformation.
It can be found in [3].
It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.
The explicit 'ret = -EIO;' has been removed because
'dma_set_mask_and_coherent()' returns 0 or -EIO, so its return code can be
used directly.

- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework

was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,

Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs

This can create an issue incase the current designated
cpu being used to collect fme pmu data got offline,
as based on current code we are not migrating fme pmu to
new target cpu. Because of that perf will still try to
fetch data from that offline cpu and hence we will not
get counter data.

An FPGA manager should not be required to provide a state() op.
Add a wrapper consistent with the other op wrappers.
Move op check to wrapper.
Default to FPGA_MGR_STATE_UNKNOWN, what noop state() ops use.
Remove unneeded noop state() ops

An FPGA manager should not be required to provide a
write_complete function if there is nothing. Move
the op check to the existing wrapper.
Default to success and remove noop function.

An FPGA manager should not be required to provide a
write_init() op if there is nothing for it do.
So add a wrapper and move the op checking.
Default to success.

This adds the approved PCI Express Device IDs for the Silicom PAC N5010
and N5011 cards (aka. Silicom Lightning Creek cards).
The N5010 features an FPGA that manages/interfaces four QSFP ports, and
allows on-board custom packet processing/filtering/routing, based on
logic loaded with user-provided FPGA bitstreams.
The N5011 cards adds a PCIe switch that exposes, in addition to the FPGA
itself, two Intel E810 (aka Columbiaville) ethernet controllers. With
this, packets can be forwarded from the FPGA to the host for further
processing.
