Blackfin: debug-mmrs: disable PERIPHERAL_MAP for IMDMA channels 2011-07-23T05:18:17+00:00 Mike Frysinger vapier@gentoo.org 2011-06-08T19:48:57+00:00 e14062563cd5702c656fc9bee14165564341be2b The documentation for the IMDMA channels appears to be incorrect. These DMA blocks don't actually have PERIPHERAL_MAP MMRs for us to access. Attempts to do so lead to system mmr hardware errors. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

So add it for RSI too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Blackfin: debug-mmrs: fix typos with gptimers/mdma/ppi 2011-05-28T21:02:56+00:00 Mike Frysinger vapier@gentoo.org 2011-05-26T21:27:36+00:00 d09fb602030e3247c21452ee2b3229baf115f71f This code was mostly developed against a BF54x, so some BF537-specific issues were missed. The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse of the EPPI block). The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the sim does not catch misreads here so that'll need to get fixed. The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct to figure that out rather than hardcoding it locally. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
