Subject: Re: [PATCH] fsldma: use PCI Read Multiple command
Date: Mon, 27 Apr 2009 18:36:58 -0700 [thread overview]
Message-ID: <49F65DBA.2090702@ovro.caltech.edu> (raw)

> How about FIFO RAM case?
If the FIFO has a fixed address, then according to
the user guide, the DMA controller won't generate
a burst transaction to it.
We can try confirming this if you'd like.
Cheers,
Dave
