bios/sdram: make read leveling robust for KUS SDRAM
...
Increases the initial delay step into the valid read window as
with the original delay I was not getting out of the noisy
transition window, as evidenced by seeing read delay windows
of only 8 LSB ~10% of the time, leading to failing memory

cpu: Adding "variant" support.
...
It is useful to support slightly different variants of the CPU
configurations. This adds a "cpu_variant" option.
For the mor1k we now have the default mor1k configuration and the
"linux" variant which enables the features needed for Linux support on
the mor1k.
Currently there are no variants for the lm32, but we will likely add a
"tiny" variant for usage on the iCE40.

Wait longer before giving up on the 2nd tftp block.
...
Previously we would wait the same number of iterations as it took us to
receive the first data block after sending the request. When using the
build in tftp server in qemu, the first wait loop succeeds (and thus
breaks when 'i' is still 0.
Since the counter was never reset between the first and second data
block, under qemu the tftp_get call would fail before ever checking if
we have received the second block of data.
Now that we initialise 'i' to 12M, we ensure that we wait the same
amount of time for the second data block as it previously did for the
third (and subsequent) blocks.
