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

2018-05-07T13:34:12+00:00

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.

drivers/ddr/fsl: Add calculation of register control words

2018-01-30T17:14:07+00:00

DDR4 RDIMM has some information in SPD to be used to calculate the
control words for register chip. The rest can be found from JEDEC
spec DDR4RCD02.

Add more SPDX-License-Identifier tags

2016-01-19T13:31:21+00:00

In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier
tag.

powerpc: Fix CamelCase warnings in DDR related code

2013-10-16T23:15:16+00:00

Some DDR related structures present in fsl_ddr_dimm_params.h, fsl_ddr_sdram.h, ddr_spd.h
has various parameters with embedded acronyms capitalized that trigger the CamelCase
warning in checkpatch.pl

Convert those variable names to smallcase naming convention and modify all files
which are using these structures with modified structures.

mpc8xxx: update module_type values from JEDEC DDR3 SPD Specification

2011-11-29T14:48:06+00:00

Newer JEDEC DDR3 SPD Specifications define several additional values for
the DDR3 module_type field which were undefined when this code was
written. Update the code to handle the newer module types.

mpc8xxx: DDR2/DDR3: Clean up DIMM-type switch statements

2011-04-04T14:24:43+00:00

The numeric constants in the switch statements are replaced by #defines
added to the common ddr_spd.h header.  This dramatically improves the
readability of the switch statments.

In addition, a few of the longer lines were cleaned up, and the DDR2
type for an SO-RDIMM module was added to the DDR2 switch statement.
