Tim Yamin	6b61e69e7b	powerpc/mpc5200: Add MDMA/UDMA support to MPC5200 ATA driver ... This patch adds MDMA/UDMA support using BestComm for DMA on the MPC5200 platform. Based heavily on previous work by Freescale (Bernard Kuhn, John Rigby) and Domen Puncer. With this patch, a SanDisk Extreme IV CF card gets read speeds of approximately 26.70 MB/sec.

Tim Yamin	e4efe3c271	powerpc/mpc5200: Bestcomm fixes to ATA support ... 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.

Sylvain Munaut	9ea68df515	[POWERPC] bestcomm: ATA task support ... This is the microcode for the ATA task and the associated support code. The microcode itself comes directly from the offical API (v2.2) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>	2007-10-16 17:09:42 -06:00
