@avpatel @hschauhan @SiFiveHolland @clementleger @pathakraul @jones-drew : I will send the patches on the mailing list for wider review before merging. It is just easier to discuss via GH PR/issues for ARC review comments.

# Describe the purpose of this series. The information you put here
# will be used by the project maintainer to make a decision whether
# your patches should be reviewed, and in what priority order. Please be
# very detailed and link to any relevant discussions or sites that the
# maintainer can review to better understand your proposed changes. If you
# only have a single patch in your series, the contents of the cover
# letter will be appended to the "under-the-cut" portion of the patch.

# Lines starting with # will be removed from the cover letter. You can
# use them to add notes or reminders to yourself. If you want to use
# markdown headers in your cover letter, start the line with ">#".

# You can add trailers to the cover letter. Any email addresses found in
# these trailers will be added to the addresses specified/generated
# during the b4 send stage. You can also run "b4 prep --auto-to-cc" to
# auto-populate the To: and Cc: trailers based on the code being
# modified.

As per the ARC review feedbacks, the current functions using base and
mask for batch mode operations on triggers doesn't describe the usage
of base and mask. Provide additional text to clarify that.

While the current fwft description says, it controls firmware
features, it enable/disables bunch of hardware features as well.

Provide additional clarification in the extension definition to
avoid ambiguity.

As per the ARC feedback,
When supervisor mode is there, medeleg must exists. There is no
SBI extension without supervisor mode. Thus, medeleg presence related
text is redundant.

As per the ARC review feedback, it was suggested that we should support
both low priority and high priority SSE events. Introduce additional IDs
for the low priority and mark the current ones as high priority.

Some of the content from the write_attributes are copied from the
read_attributes which is not correct. Fix the description.

As per the ARC review feedback, it was suggested that the supervisor
software should be able to distinguish between denial reasons if it
was due to locked.

While at it, add some clarification about set operation when the
requested and existing values are same.
