Add support for UltraSoc System Memory Buffer.
Change since v8:
- Insert a blank line at the end of the config tag in Kconfig.
- Fix the "llseek" initialization.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Change since v7:
- Use the macros for register bit flags and numbers of resource.
- Fix punctuation.
- Update the Date tag and the KernelVersion tag in the document.
- Link: https://lore.kernel.org/lkml/[email protected]/
Change since v6:
- Modify the code style and driver description according to Suzuki's comment.
- Modify configuration of "drvdata->reading", to void problems in open/read
concurrency scenario.
- Rename the macro of "SMB_FLOW_MASK".
- Use the "handle->head" to determine the page number and offset.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Change since v5:
- Address the comments from Suzuki, add some comments in SMB document, and modify
configuration of "drvdata->reading", to void problems in multi-core concurrency scenario
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Change since v4:
- Add a simple document of SMB driver according to Suzuki's comment.
- Address the comments from Suzuki.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Change since v3:
- Modify the file header according to community specifications.
- Address the comments from Mathieu.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Change since v2:
- Move ultrasoc driver to drivers/hwtracing/coresight.
- Link: https://lists.linaro.org/pipermail/coresight/2021-November/007310.html
Change since v1:
- Drop the document of UltraSoc according to Mathieu's comment.
- Add comments to explain some private hardware settings.
- Address the comments from Mathieu.
- Link: https://lists.linaro.org/pipermail/coresight/2021-August/006842.html
Change since RFC:
- Move driver to drivers/hwtracing/coresight/ultrasoc.
- Remove ultrasoc-axi-com.c, as AXI-COM doesn't need to be configured in
basic tracing function.
- Remove ultrasoc.c as SMB does not need to register with the ultrasoc core.
- Address the comments from Mathieu and Suzuki.

There are a few patchset that are both substantial and complex to
review on the log. As such reviewing will take longer than usual.
