87b1fbb66c tornado/cpu/: new version of the CPU board (WIP) 
Differences:
- a bit smaller, 42.25 x 22.5 mm. The old version was 43.75 x 25.25 mm
- NXP LPC1112FHN33/202 MCU (Cortex-M0)
- step-down converter for the 3.3 V supply
- all-digital 3D acceleration sensor
- one local LED
- push-pull card holder

Note that the interface to the LED modules has changed as well. New
features:
- high supply voltage
- optional sharing of regulator
- double ground

45f14d214a tornado/fw/tornado.c: experimental code to log ADC samples to memory card 
For a yet unknown reason, writing to the card fails if also processing
the samples. Maybe it's some side-effect of switching the LEDs.

0703611bbd tornado/fw/mmc.c (mmc_wait): add 1 ms delay to wait loop

with an explicit delay than with a loop count.
