[PATCH v2 2/7] fpga: sec-mgr: enable secure updates

Extend the FPGA Intel Security Manager class driver to include an update/filename sysfs node that can be used to initiate a security update. The filename of a secure update file (BMC image, FPGA image, Root Entry Hash image, or Code Signing Key cancellation image) can be written to this sysfs

[PATCH v2 3/7] fpga: sec-mgr: expose sec-mgr update status

Extend the Intel Security Manager class driver to include an update/status sysfs node that can be polled and read to monitor the progress of an ongoing secure update. Sysfs_notify() is used to signal transitions between different phases of the update process. Signed-off-by: Russ Weight --- v2:

[PATCH v2 6/7] fpga: sec-mgr: enable cancel of secure update

Extend the Intel Security Manager class driver to include an update/cancel sysfs file that can be written to request that an update be canceled. The write may return EBUSY if the update has progressed to the point that it cannot be canceled by software or ENODEV if there is no update in progress.

[PATCH v2 5/7] fpga: sec-mgr: expose sec-mgr update size

Extend the Intel Security Manager class driver to include an update/remaining_size sysfs node that can be read to determine how much data remains to be transferred to the secure update engine. This file can be used to monitor progress during the "writing" phase of an update. Signed-off-by: Russ

[PATCH v2 7/7] fpga: sec-mgr: expose hardware error info
