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.

8d59f8a206 libubb/: add experimental physical memory allocation/mapping module 
The API is fairly inflexible and is very likely to change.

47140384ee ubb-patgen/hw/: a simple resistor on CMD is sufficient - no need for a cap 
Cheaper and easier to control.

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

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.)
