From: Bin Meng
The old Wind River email address (bin.m...@windriver.com) is no longer
available due to an internal infrastructure change within the company.
While a new email address (bin.meng...@windriver.com) has been assigned
to me, I am unable to find a way to send this patch directly from
The Wind River email address might change in the future. Use my
personal email address instead.

There is already a piece of codes inside the segment traversal loop
that checks for zero-sized loadable segments for not creating empty
ROM blobs. Let's move this check to the beginning of the loop to
cover both scenarios.

to be unnecessary, as the actual size is much smaller than what the

Good point
From: Bin Meng
At present with a debugger attached sstc CSRs can only be accssed
when CPU is in M-mode, or configured correctly.
Fix it by adjusting their predicate() routine logic so that the
static config check comes before the run-time check, as well as
adding a debugger check.

Move sstc()/sstc32() to where all predicate() routines live, and
smstateen_acc_ok() to near {read,write}_xenvcfg().

It's worth noting that the vector CSR predicate() has a similar
run-time check logic to the FPU CSR. With the previous patch our
gdbstub can correctly report these vector CSRs via the CSR xml.

riscv_csrrw_check() already does the generic privilege level check
hence there is no need to do the specific M-mode access check in
the mseccfg predicate().
With this change debugger can access the mseccfg CSR anytime.
