19c04403c0 ubb-vga/web/index.html: correction - it's the response we fake, not the "busy"
"Busy" is actually another signal, on DAT0, and sent betweeen blocks.
We don't fake that one (so far), although the mechanism would be similar.

88e09d003b index.html: moved author's name; file format of images we can load was incorrect
- index.html: don't boastfully start the page with my name. The footer
  will do well enough.
- index.html: the image format we can load is PPM (pixmap), not PNM
  (anymap)

ba1d297643 ubb-vga: new option -2 to keep on refreshing the LCD display (experimental)
"Experimental" means that it doesn't seem to work at the moment.

- regs4740.h (_LCD, LCDCTRL): added the LCD control register
- ubb-vga.c (old_lcdctrl, tame_lcd, restore_lcd): make the LCD controller
  use short bursts, to reduce the bus access latency for other users
- ubb-vga.c (keep_lcd, setup_noirq, cleanup_noirq, usage, main): new
  option -2 to keep on refreshing the LCD display

  get_timer to setup_noirq
- ubb-vga.c (cleanup, cleanup_noirq): moved calls to release_timer
  and enable_lcd to cleanup_noirq
- ubb-vga.c (cleanup, main): "cleanup" is now empty; removed it

6f5a8ccf5a ubb-vga: added draft for "productized" design
- vga-ben.pro, vga-ben.sch, vga-ben.cmp, vga-ben.pro: similar to
  ubb-vga.sch, but with R and Y swapped (for better grounding), the VGA
  connector replaced by solder pads, and added pads for the shield
- Makefile (schp, brd): new targets for editing vga-ben

01d33e28a7 ubb-vga.c (delay): try to compensate for APB jitter (experimental)
First, we extend all deadlines a litte to make sure we never have to
wait negative time. Second, we get the timer value at the end of the
wait and CPU-loop for the difference between the actual value and the
ideal (extended) value.

5817669968 ubb-vga: try to clock MSC faster than the MMC bus; new video mode "640x480/61"
- ubb-vga.c (mode_db): added new mode "640x480/61"
- ubb-vga.c (setup, line): MSC_CLKRT is reset when the MSC resets. Moved
  it from "setup" to "line".
- ubb-vga.c (clkrt, setup, line): pick the highest available MSC clock
  and adjust the bus clock divider accordingly
- ubb-vga.c (main): added commented-out clock debugging output
- README: added XEN-1510T result for "640x480/61"

6d8c8dd951 ubb-vga: use a free-running counter instead of resetting it for each line
Two benefits:
1) We don't accumulate errors from the delay between the timer reset and
   the deadline preceding it
2) In the future, we may use WAIT to wait for timer expiration, which
   should cause less bus activity and is should also reduce jitter

- regs4740.h (TFR. TFSR, TFCR, TDHR): added more timer registers
- ubb-vga.c (until): renamed to "delay" and changed to measure relative
  to the last deadline
- ubb-vga.c (line, hdelay, frame): replaced "until" with "delay"
- ubb-vga.c (hdelay, frame, session): reset the timer only once, at
  the beginning of the session
- ubb-vga.c (frame): we didn't wait for the horizontal back porch of
  the last image line

a3cea3573c ubb-vga: send a line's last DMA transfer also if only partially filled
This caused 800x600 images to be cut off, because the line length is
not a multiple of 64 bytes.

- ubb-vga.c (session): make the allocation a multiple of the DMA
  transfer size
- ubb-vga.c (line): round number of transfers up instead of down
- ubb-vga.c (mode_db): line duration of 800x600/54 was a bit to short

3ea6b9852e ubb-vga: make lines end in black (and not in overscan)
- ubb-vga.c (line): send a 0 word at the end of the line, to avoid
  overscan (we use PIO to synchronize with CPU timing)
- ubb-vga.c (mode_db): updated line length of 640x480 resolutions for
  correct termination

0dbf29e599 physmem.c: improved correctness and efficiency of alignment
- physmem.c (align_brk): don't waste memory if already aligned
- physmem.c (ALIGN, calloc_phys_vec): align by DMA transfer size
- physmem.c (calloc_phys_vec): make sure allocations don't straddle
  page boundaries
- physmem.c (xlat_one): print "unsigned long" with %lx, not %x
