* ARM: uniphier: use FIELD_GET() to get access to revision register fieldsMasahiro Yamada2020-08-181-11/+10
| | | | | | Define register fields as macros, and use FIELD_GET(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: de-couple SG macros into base address and offsetMasahiro Yamada2019-07-101-1/+1
| | | | | | | | | The SG_* macros represent the address of SoC-glue registers. For a planned new SoC, its base address will be changed. Turn the SG_* macros into the offset from the base address. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | 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 <trini@konsulko.com>
* ARM: uniphier: fix MODEL field of REVISION registerMasahiro Yamada2017-05-171-1/+1

* ARM: uniphier: simplify SoC ID get functionMasahiro Yamada2017-01-221-0/+35
Currently, uniphier_get_soc_type() converts the SoC ID (this is read from the revision register) to an enum symbol to use it for SoC identification. Come to think of it, there is no need for the conversion in the first place. Using the SoC ID from the register as-is a straightforward way.
