SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

fsl_dma: fix support for 83xx DMA engine

2011-07-07T00:09:27Z

Commit 359ec4931944adb885882deb9b781e4095eabc94 broke support for the Freescale DMA engine on the 83xx parts. This is due to using registers which do not exist on 83xx. Remove the attribute register accesses from the 83xx build. Signed-off-by: Ira W. Snyder Cc: York Sun Cc: Peter Tyser Cc: Kumar Gala Signed-off-by: Kim Phillips

fsl_dma: Make DMA transactions snoopable

2009-07-02T04:12:05Z

Make DMA transactions snoopable so that CPUs can keep caches up-to-date. This allows dma transactions to be used for operations such as memory copies without any additional cache control operations. Signed-off-by: Peter Tyser Signed-off-by: Kumar Gala

fsl_dma: Fix Channel Start bug in dma_check()

2009-07-02T04:07:45Z

The Channel Start (CS) bit in the Mode Register (MR) should actually be cleared as the comment in the code suggests. Previously, CS was being set, not cleared. Assuming normal operation of the DMA engine, this change shouldn't have any real affect. Signed-off-by: Peter Tyser Signed-off-by: Kumar Gala
