| | | | | | | | | | | | | | | | The Cortex-R* processors are a mid-range CPUs for use in deeply-embedded, real-time systems. It implements the ARMv7-R architecture, and includes Thumb-2 technology for optimum code density and processing throughput. Except for MPU(Memory Protection Unit) and few CP15 registers, most of the features are compatible with v7 architecture. So,reuse the same armv7 folder and introduce a new config CPU_V7R in order to differentiate from v7 based platforms.

* arm: v7: Kconfig: Rename CPU_V7 as CPU_V7ALokesh Vutla2018-05-0723-76/+76
| | | | | | | | | | | | | | | | | Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

* syscon: add Linux-compatible syscon APIMasahiro Yamada2018-05-072-0/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The syscon implementation in U-Boot is different from that in Linux. Thus, DT files imported from Linux do not work for U-Boot. In U-Boot driver model, each node is bound to a dedicated driver that is the most compatible to it. This design gets along with the concept of DT, and the syscon in Linux originally worked like that. However, Linux commit bdb0066df96e ("mfd: syscon: Decouple syscon interface from platform devices") changed the behavior because it is useful to let a device bind to another driver, but still work as a syscon provider. That change had happened before U-Boot initially supported the syscon driver by commit 6f98b7504f70 ("dm: Add support for generic system controllers (syscon)"). So, the U-Boot's syscon works differently from the beginning. I'd say this is mis-implementation given that DT is not oriented to a particular project, but Linux is the canon of DT in practice. The problem typically arises in the combination of "syscon" and "simple-mfd" compatibles. In Linux, they are orthogonal, i.e., the order between "syscon" and "simple-mfd" does not matter at all. Assume the following compatible. compatible = "foo,bar-syscon", "syscon", "simple-mfd"; In U-Boot, this device node is bound to the syscon driver (driver/core/syscon-uclass.c) since the "syscon" is found to be the most compatible. Then, syscon_get_regmap() succeeds. However, compatible = "foo,bar-syscon", "simple-mfd", "syscon"; does not work because this node is bound to the simple-bus driver (drivers/core/simple-bus.c) in favor of "simple-mfd" compatible. The compatible string "syscon" is just dismissed. Moreover, compatible = "foo,bar-syscon", "syscon"; works like the first case because the syscon driver populates the child devices. This is wrong because populating children is the job of "simple-mfd" (or "simple-bus"). This commit ports syscon_node_to_regmap() from Linux. This API does not require the given node to be bound to a driver in any way.

* regmap: clean up regmap allocationMasahiro Yamada2018-05-079-43/+24
| | | | | | | | | | | | | | | | | | Putting zero length array at the end of struct is a common technique to embed arbitrary length of members. There is no good reason to let regmap_alloc_count() branch by "if (count <= 1)". As far as I understood the code, regmap->base is an alias of regmap->ranges[0].start, but it is not helpful but make the code just ugly. Rename regmap_alloc_count() to regmap_alloc() because the _count suffix seems pointless.

* SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini2018-05-07121-239/+121
| | | | | | | | | | | | | | | | | | | | | | | 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 multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document.
