2008-12-21powerpc/mpc5200: Disable bestcomm prefetching when ATA DMA enabledGrant Likely
When ATA DMA is enabled, bestcomm prefetching does not work. This patch adds a function to disable bestcomm prefetch when the ATA Bestcomm task is initialized. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2008-12-21powerpc/mpc5200: Bestcomm fixes to ATA supportTim Yamin
1) ata.h has dst_pa in the wrong place (needs to match what the BestComm task microcode in bcom_ata_task.c expects); fix it. 2) The BestComm ATA task priority was changed to maximum in bestcomm_priv.h; this fixes a deadlock issue experienced with heavy DMA occurring on both the ATA and Ethernet BestComm tasks, e.g. when downloading a large file over a LAN to disk.

2007-10-16[POWERPC] bestcomm: core bestcomm support for Freescale MPC5200Sylvain Munaut
This patch adds support for the core of the BestComm API for the Freescale MPC5200(b). The BestComm engine is a microcode-controlled / tasks-based DMA used by several of the onchip devices. Setting up the tasks / memory allocation and all common low level functions are handled by this patch. The specifics details of each tasks and their microcode are split-out in separate patches. This is not the official API, but a much cleaner one. (hopefully) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
