Werner Almesberger c6306ff591 ubb-patgen/ubb-patgen.c: DMA works now. Get rid of the PIO option. 2013-01-14 23:29:23 -03:00
Werner Almesberger b6ee672266 ubb-patgen/: flush dcache and write buffer before doing DMA 2013-01-14 23:26:24 -03:00
Werner Almesberger 908b0631d1 ubb-patgen/ubb-patgen.c: DMA has mystery glitches. Use PIO for now. 2013-01-14 22:18:46 -03:00
Werner Almesberger 3febc9072a ubb-patgen/ubb-patgen.c (dma_pattern): move pattern parser to parse_pattern
... and introduce pattern multipliers <hex>{<repetitions>}

Werner Almesberger e5cb1c98ea ubb-patgen/ubb-patgen.c: describe the pattern transfer logic 2013-01-14 17:01:13 -03:00
Werner Almesberger fa8b5b6324 ubb-patgen/ubb-patgen.c: clean up pattern generation and boundaries
The main change is to use only a single transfer and thus avoid tri-stating
DATx during the command phase. To control the timing, we put the first word
"manually" into the FIFO, wait until it has been sent on the bus, and only
then DMA the rest.

Werner Almesberger 09bf9c23ab ubb-patgen/: add DMA-based pattern transfer (WIP)
Works for some patterns but seems to have issues at the edge of
transfers. Clock selection also needs more work.

Werner Almesberger 8d59f8a206 libubb/: add experimental physical memory allocation/mapping module
The API is fairly inflexible and is very likely to change.
2013-01-14 03:54:17 -03:00
Werner Almesberger 47140384ee ubb-patgen/hw/: a simple resistor on CMD is sufficient - no need for a cap
Cheaper and easier to control.

Werner Almesberger 52ce1947c5 ubb-patgen/: UBB-based pattern generator (WIP)
For now, it only knows to synthesize the clock and to output it.

Werner Almesberger 127e18d7ed libubb/Makefile: get rid of version bureaucracy (suggested by Kyak) 2013-01-07 16:28:59 -03:00
Werner Almesberger b18d688570 libubb/mmcclk.c (mmcclk_first): base clock calculation on state of CPCCR.PCS
Also rename BEN_SYS_CLK_HZ to BEN_PLL_CLK_HZ, since the system clock
depends on CPCCR.PCS (while we assume BEN_PLL_CLK_HZ to be constant.)

Werner Almesberger 2004d8c90a ubblib/Makefile: don't generate the versioned shared library

Werner Almesberger 64c14fb709 libubb/Makefile: build also a shared version of libubb; better cleanup
The improved cleanup removes the library after a partially successful build.
