Drop doublerate parameter and replace it with a generic speed parameter.
Additionally, on linux you can supply any (non-standard) baudrate.

New week, new review: the memories. Let's begin with the DRAM:
- nitpicking: the official names of pins 20 and 47 of U14/U15 are
LDM/UDM, not LDQM/UDQM
- the DRAM data sheet [1] says the -5B version (which is what we
have) needs Vdd = VddQ = 2.6 +/- 0.1 V for DDR400 operation. If
operating
Last but not least, I had a quick look at the FPGA, checking the
things we've changed since M1rc3. All looks well.
The FPGA has numerous quirky details, so it would be good if
someone who has more experience with the hardware side of this
chip could also have a look at the schematics.
I think
