RISCV requires that timer interrupts be handled in machine
mode and delegated as necessary. Also you can only reset the
timer interrupt by writing to mtimecmp. Further, you must
write a number > mtime, not just != mtime. This rather clumsy
situation requires that we write some value into the future
into mtimecmp lest we never be able to leave machine mode as
the interrupt either is not cleared or instantly reoccurs.
This current code is tested and works for harvey (Plan 9)
timer interrupts.

This reverts commit c86da67436.
Alas, I have to disagree with this in every single line. The comment
added to the top of the file only applies to a single function therein
which sits over a hundred lines below. That's not much helpful. More-
over, the link in the comment is already down ofc.
The comment is also irritating as it doesn't state in which way (enco-
ding!) it applies to the code, which presumably led to the wrong in-
terpretation of the IDs.
At last, if anything should have changed it is the strings, the IDs
are resolved to. `smbios_fill_dimm_manufacturer_from_id()` has to
resolve the IDs it gets actually fed and not a random selection from
any spec.
Since I digged into it, here's why the numbers are correct: The func-
tion started with the SPD encoding of DDR3 in mind. There, the lower
byte is the number of a "bank" of IDs with an odd-parity in the upper
most bit. The upper byte is the ID within the bank. The "correction"
was to clear the parity bit for naught. The function was later exten-
ded with IDs in the DDR2-SPD encoding (which is actually 64-bit not
16). There, a byte, starting from the lowest, is either an ID below
127 plus odd-parity, or 127 which means look in the next byte/bank.
Unused bytes seem to be filled with 0xff, I guess from the 0xff2c.

with two DIMMs on the second channel). However, this port is for
the Stoney processor which is a single channel. As a result, the
second DIMM slot is not usable. A future improvement could involve
a port using a different processor, with unique devicetree files

For Chrome OS the normal MRC cache should be cleared when a hardware
retrain recovery request is observed. The reason is that since there
are 2 different MRC cache slots there needs to be a mechanism which
allows an end user make a system bootable again if the MRC settings
happen to not allow the system to boot any longer. Therefore, one
just needs to enter recovery with the hardware retrain flag and
the system normal MRC cache slot will be invalidated.
