Hi Sean,
Many thanks again for reviewing our code! We really appreciate it. Will
fix the things you're suggesting ;p Though I have a few questions in
line in the comment. Also, checkpatch didn't catch any of the identation
issues. I was wondering if there are some specific flags to enable some
of the checks? I'm running ./utils/checkpatch.pl this.patch right now.

It shows correct formatting in my client, and there's no warning in
checkpatch for some reason

>> +OpenPiton RISC-V SoC
>> +--------------------
>> +OpenPiton is an open source, manycore processor and research
>> platform. It is a tiled manycore framework scalable from
>> one to 1/2 billion cores. It supports a number of ISAs including
>> RISC-V with its P-Mesh cache coherence protocol and
>> networks on chip. It is highly configurable in both core and uncore
>> components. OpenPiton has been verified in both ASIC
>> and multiple Xilinx FPGA prototypes running full-stack Debian linux.

>> +-------------------------

>> +This board supports S-mode u-boot as well as M-mode SPL

Because u-boot SPL will just to CONFIG)SYS_TEXT_BASE ( where opensbi is
). If I change that, it will just jump to the wrong location.

So this is the part where it was a little confusing. Disabling debug
uart acutally doesn't work for some reason, so we had to keep it open.
Will submit another patch if we got it working with debug uart turned off.
