Done this week: * Completed milestone M1 (established required APIs) * Published some info about DMA APIs on wiki - see http://wiki.freebsd.org/SOC2010JakubKlama * Done research about configuring DMA channel allocations for various kernel subsystems (for now, it will be hardcoded in kernel, but easy to refactor when FDT on this platform became available) * Added error handling in EDMA3 driver Plans for next week: * Finish EDMA3 driver * Test transfers in userspace using char device driver * Do some research about using DMA in kernel memcpy() and bzero() * Clean up existing code -- Jakub Klama.
