* Blackfin: only flag L1 instruction for DMA memcpyMike Frysinger2009-02-021-10/+4
| | | | | | | | | The performance difference from doing an 8 bit DMA memcpy vs an optimized core memcpy can be pretty big when you add in the overhead of setting up the MDMA registers, cache flushes, etc... So only use dma_memcpy() when we actually require it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: rewrite cache handling functionsMike Frysinger2009-02-021-0/+4
| | | | | | | Take the cache flush functions from the kernel as they use hardware loops in order to get optimal performance. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: cache core/system clock valuesMike Frysinger2009-02-021-0/+2
| | | | | | | | Calculating the clocks requires a bit of calls to gcc math functions, so cache the values after the first run since they'll most likely never change once U-Boot is up and running. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix dcache handling when doing dma memcpy'sMike Frysinger2009-01-281-1/+1
| | | | | | | | Our dcache invalidate function doesn't just invalidate, it also flushes. So rename the function accordingly and fix the dma_memcpy() function so it doesn't inadvertently corrupt the data destination. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* punt Blackfin VDSP headers and import sanitized/auto-generated onesMike Frysinger2008-02-041-0/+215
