ARM: socfpga: Rename the gen5 sdram driver to more specific name

2018-05-18T08:30:47Z

Current sdram driver is only applied to gen5 device, hence it is better to rename sdram driver to more specific name which is related to gen5 device. Signed-off-by: Tien Fong Chee

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

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48Z

We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini

ddr: altera: Repair DQ window centering code

2016-04-20T09:28:45Z

The code uses a lot of signed numbers, which ended up in variables of unsigned type, which resulted in all sorts of underflows. This in turn caused incorrect calibration on certain boards. Moreover, repair the readout of the DQ delay, which was being pulled from wrong register. Signed-off-by: Marek Vasut Cc: Dinh Nguyen Cc: Chin Liang See
