dae21696b3 ubb-vga.c: a bit more cleanup
- ubb-vga.c: added more section titles
- ubb-vga.c (pick, pattern): grouped pixel-generating functions with
  image generation
- ubb-vga.c (usage, main): properly parse command-line options ("getopt"
  is a bit of overkill at the moment but will be needed later)

8bd7199d9e ubb-vga.c: removed commented-out code from earlier experiments
The history of the split prefetch code:

Once up on a time, I thought that it was important to stay very close
to the "official" pixel clock. We could do this when copying 32 bit
words from cache to the GPIO set/clear registers, but not when
shifting 8 bit values as we do now.

One problem with 32 bit values is that transferring that amount of
data exceeds the time available in the hsync pulse. Hence the idea
to split the prefetch between hsync pulse and horizontal front porch.

Note that we also split prefetches between the two VGA lines of each
QVGA line. This commit does not change that mechanism.

- ubb-vga.c (line, frame): removed code fragments for prefetch split
  between hsync pulse and front porch
- ubb-vga.c (line, frame): remove code fragments for measuring time
  relative to the rising edge of hsync (and letting the prefetch time
  control the hsync length), not the falling edge

9778f3fb1b uart/avrdude: various corrections
nanonote-uart.patch:

- avrdude.conf.in: CLK is reserved for clock output

nanonote.patch:

  zero-based

  setting the pin repeatedly, just add the delay we need to
  pgm->ispdelay+100

- nanonote.c (nanonote_getpin, nanonote_open): begin with all pins set
  to output and switch MISO only when read
