== Changes since q4a05 ==

* r2047 Fixed bug in ec-flash introduced by recent changes.
* r2046 fixed problem with cursor being off.
* r2045 Use board ID 1a1 if board-id@ fails.
* r2043 factored out HDD LED setting code, added game key reading code.
* r2042 SD driver - tune data timing for 50 MHz operation.
* r2040 DCON driver - freeze is now a no-op because, lacking frame storage, it doesn't work on this hardware.
* r2039 boardrev.fth - initial revision
* r2038 (1) Startup sound now plays in the background for faster startup (2) Use 3.3V signals GPIO 97,98 for RTC (bitbanging instead of using the TWSI hardware) (3) Made the startup sequence more like the 1.5 version
* r2037 Get board revision from the EC.
* r2036 implemented a bunch of EC commands.
* r2035 Changed ps2mouse.fth to use my-space instead of my-unit for set-port; my-unit does not work right.
* r2034 SDHCI - solidified support for SDHCI version 3 clock divisor layout and made 50 MHz operation work reasonably well for XO-1.75.
* r2033 Fixed race condition in EC SPI module.
* r2031 strobe HDD_LED# during fs-update. The LED is toggled once for each zblock: line in the input file. This shows the processing speed, and is affected initially by complexity of decompression, and eventually by SD card write rate. Faster and slower SD cards are more easily compared. Cost of 1.7 microseconds per LED toggle, but as writes to SD are asynchronous the run time is unchanged.
* r2029 int and ext were swapped.
