There was an assumption that all SPI controllers could
consume a full page of data to write. However, that
assumption doesn't hold when spi_crop_chunk() indicates
sizes smaller than page size. If the requested offset isn't
page aligned from the start then writes will fail corrupting
data since a page boundary isn't honored.
The spansion driver needed quite a bit more work to honor
the spi_crop_chunk() result. It now mimics the other
driver's code. Also, needed to add spi_crop_chunk() to
marvell/bg4cd SoC to make google/cosmos build. SPI obviously
doesn't work on that platform, but it fixes the build error.

flash memory and XIP romstage is at the same location.
As SPI master by default decodes all of top 16MiB below
4GiB, initial cache-as-ram line fills may have actually
read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.
There are no reasons to have this as board-specific setting.

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.

I've recently added an assertion to ensure that the effective I2C
frequency on Rockchip SoCs is not too far off the 400KHz target due to
divisor rounding errors. A 10KHz margin worked fine for RK3399, but it
turns out that RK3288 actually only ever hit 387KHz since its I2C clocks
are based off the already pretty low 75MHz PCLKs. While we could
probably change the PCLKs to make this closer, that seems like a too
intrusive change for something that has already worked just fine for
years, so just loosen the restriction a little more instead.
