2022-06-08fpga: m10bmc-sec: expose max10 canceled keys in sysfsRuss Weight1-0/+54
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.

2022-06-08fpga: m10bmc-sec: create max10 bmc secure updateRuss Weight3-0/+149
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.

2022-05-10fpga: dfl: Allow Port to be linked to FME's DFLMatthew Gerlach2-0/+10
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.

2022-01-25fpga: dfl: pci: Remove usage of the deprecated "pci-dma-compat.h" APIChristophe JAILLET1-10/+5
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.

2021-07-21bus: Make remove callback return voidUwe Kleine-König1-3/+1
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.
