10 years 8 months libubb/mmcclk.c (BUS_LIMIT_MHZ): explain the 56 MHz limit
10 years 8 months ubb-patgen/ubb-patgen.c: new option -m MASK to choose which DATx lines to use
10 years 8 months ubb-patgen/ubb-patgen.c: new option -p to force interpretation as pattern
10 years 8 months ubb-patgen/ubb-patgen.c: accept file (- for standard input) as pattern source
10 years 8 months ubb-patgen/table/mktab: make the long vertical axes thinner
10 years 8 months ubb-patgen/table/: generate a PNG with a table of MMC bus clock frequencies
10 years 8 months ubb-patgen/ubb-patgen.c: option -q when dumping frequencies suppressed details
10 years 8 months ubb-patgen/ubb-patgen.c: "ubb-patgen -f FREQ" calculates the frequency
10 years 8 months ubb-patgen/ubb-patgen.c: remove pattern frequency and use -f for bus clock
10 years 8 months ubb-patgen/ubb-patgen.c: clean up usage (-c selects clkout only; -C to monitor)
10 years 8 months libubb/mmcclk.c (mmcclk_start): also reset the MMC controller
10 years 8 months ubb-patgen/ubb-patgen.c: clean up section structure
10 years 8 months ubb-patgen/ubb-patgen.c (dma_pattern): mlockall (before address translation and DMA)
10 years 8 months ubb-patgen/ubb-patgen.c: DMA works now. Get rid of the PIO option.
10 years 8 months ubb-patgen/: flush dcache and write buffer before doing DMA
10 years 8 months ubb-patgen/ubb-patgen.c: DMA has mystery glitches. Use PIO for now.

10 years 8 months ubb-patgen/ubb-patgen.c (dma_pattern): move pattern parser to parse_pattern
10 years 8 months ubb-patgen/ubb-patgen.c: describe the pattern transfer logic
10 years 8 months ubb-patgen/ubb-patgen.c: clean up pattern generation and boundaries
10 years 8 months ubb-patgen/: add DMA-based pattern transfer (WIP)
