2020-08-18ARM: uniphier: use FIELD_GET() to get access to revision register fieldsMasahiro Yamada
Define register fields as macros, and use FIELD_GET(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-07-10ARM: uniphier: detect register base addresses run-timeMasahiro Yamada
Until the last SoC, the register addresses have been hard-coded because they are always constant. For a planned new SoC, the register bases will be completely changed. I insist on supporting multiple SoCs/boards by a single defconfig (uniphier_v8_defconfig) since duplicating similar defconfig files is a maintenance burden. The base addresses must be fixed-up at run-time somehow. Previously, the board init code identified the SoC by reading out the SG_REVISION register. This is much easier than parsing DT. You cannot do it any more because the base address of SG will be changed. The SG_REVISION register exists to read out the SoC ID, but you never know its address before identifying the SoC. Oh well. So, the possible solution is to parse the DT, and find out the node with "*-soc-glue" compatible string. Then, sg_base is set to the value of the "reg" property. The sc_base is set up likewise. It is worth noting a pit-fall. Having sc_base and sg_base in the global scope will make the life easier, but the global variables are poorly supported before the relocation. In fact, the .bss section overwraps with DT. Allocating them in the .bss section would break DT. So, I gave dummy initializers to assign them in the .data section.

2019-07-10ARM: uniphier: de-couple SG macros into base address and offsetMasahiro Yamada
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>
2019-06-29ARM: uniphier: move sg_set_{pinsel, iectrl} to more relevant placesMasahiro Yamada
Move the sg_set_pinsel macro to arch/arm/mach-uniphier/arm32/debug_ll.S since it is not used anywhere else. Move the C functions sg_set_{pinsel,iectrl} to debug-uart.c since they are not used anywhere else. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2017-05-17ARM: uniphier: add more init code for PXs3Masahiro Yamada
Add the boot device table and reset deassertion for eMMC. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Set the same PHY parameters as the Boot ROM uses. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-01-22ARM: uniphier: simplify SoC ID get functionMasahiro Yamada
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.

2016-05-26ARM: uniphier: add PH1-LD11 SoC supportMasahiro Yamada
This is a low-cost ARMv8 SoC from Socionext Inc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-04-24ARM: uniphier: add PH1-LD20 SoC supportMasahiro Yamada
This is the first ARMv8 SoC from Socionext Inc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-04-24ARM: uniphier: add sg_set_iectrl_range()Masahiro Yamada
For PH1-LD20 or later, per-pin input-enable control is supported, that is, we need to set-up IECTRL registers for a group of pins. This helper function will be useful for a bunch of register settings. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-03-24ARM: uniphier: add sg_set_iectrl() functionMasahiro Yamada
This helper function would be useful for new SoCs with per-pin input enable controlling, such as PH1-LD20, PH1-LD11, etc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-03-01ARM: uniphier: fix warnings reported by aarch64 compilerMasahiro Yamada
The UniPhier SoC family has not supported ARMv8 yet, but these would cause warnings if they were compiled with a 64bit compiler. Before adding the ARMv8 support really, fix them now. Because UniPhier SoCs do not support Large Physical Address Extension, casting "phys_addr_t" into "unsigned long" would carry the address as is.
