part of the diffstat
- habanalabs driver update with support for new hardware and
features, the second largest part of the diff.

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.

Currently we use PORTn_OFFSET to locate PORT DFLs, and PORT DFLs are not
connected FME DFL. But for some cases (e.g. Intel Open FPGA Stack device),
PORT DFLs are connected to FME DFL directly, so we don't need to search
PORT DFLs via PORTn_OFFSET again. If BAR value of PORTn_OFFSET is 0x7
(FME_PORT_OFST_BAR_SKIP) then driver will skip searching the DFL for that
port. If BAR value is invalid, return -EINVAL.

The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.
The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.
