Now that include/config/auto.conf is only included by Makefiles, we can change it into a more Make-friendly form. Previously, Kconfig output string values enclosed with double-quotes (both in the .config and include/config/auto.conf): CONFIG_X="foo bar" Unlike shell, Make handles double-quotes (and single-quotes as well) verbatim. We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process. Anyway, quoted strings were always PITA for our Makefiles. This commit changes Kconfig to stop quoting in include/config/auto.conf.

Fisrt off, the compatible property used an obsolete compatibility string; this caused the initialization to be skipped. Next, the register map was not given enough space to allocate ring descriptors, this caused module initialization to abort. Finally, we need to mark this device as big-endian as needed by openrisc.

This is part of kernel tinification efforts. - Final piece of removing storing the full path for every DT node. The prerequisite conversion of printk's to use device_node format specifier happened in 4.14. - Sync with current upstream dtc.

Small Things: - Move OpenRISC docs into Documentation and clean them up - Document previously undocumented devicetree bindings - Update the or1ksim dts to use stdout-path OpenRISC SMP support details: - First the "use shadow registers" and "define CPU_BIG_ENDIAN as true" get the architecture ready for SMP. - The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and qrwlocks" add the SMP locking infrastructure as needed. Using the qspinlocks and qrwlocks as suggested by Peter Z while reviewing the original spinlocks implementation. - The "support for ompic" adds a new irqchip device which is used for IPI communication to support SMP. - The "initial SMP support" adds smp.c and makes changes to all of the necessary data-structures to be per-cpu. The remaining patches are bug fixes and debug helpers which I wanted to keep separate from the "initial SMP support" in order to allow them to be reviewed on their own. This includes: - add cacheflush support to fix icache aliasing - fix initial preempt state for secondary cpu tasks - sleep instead of spin on secondary wait - support framepointers and STACKTRACE_SUPPORT - enable LOCKDEP_SUPPORT and irqflags tracing - timer sync: Add tick timer sync logic - fix possible deadlock in timer sync, pointed out by mips guys Note: the irqchip patch was reviewed with Marc and we agreed to push it together with these patches" * tag 'for-linus' of git://github.com/openrisc/linux: openrisc: fix possible deadlock scenario during timer sync openrisc: pass endianness info to sparse openrisc: add tick timer multi-core sync logic openrisc: enable LOCKDEP_SUPPORT and irqflags tracing openrisc: support framepointers and STACKTRACE_SUPPORT openrisc: add simple_smp dts and defconfig for simulators openrisc: add cacheflush support to fix icache aliasing openrisc: sleep instead of spin on secondary wait openrisc: fix initial preempt state for secondary cpu tasks openrisc: initial SMP support irqchip: add initial support for ompic dt-bindings: add openrisc to vendor prefixes list openrisc: use qspinlocks and qrwlocks openrisc: add 1 and 2 byte cmpxchg support openrisc: use shadow registers to save regs on exception dt-bindings: openrisc: Add OpenRISC platform SoC Documentation: openrisc: Updates to README Documentation: Move OpenRISC docs out of arch/ MAINTAINERS: Add OpenRISC pic maintainer openrisc: dts: or1ksim: Add stdout-path 2017-11-08T17:20:24+00:00 Masahiro Yamada yamada.masahiro@socionext.com 2017-11-02T02:51:25+00:00 urn:sha1:74ce1896c6c65b2f8cccbf59162d542988835835 We need to add "clean-files" in Makfiles to clean up DT blobs, but we often miss to do so. Since there are no source files that end with .dtb or .dtb.S, so we can clean-up those files from the top-level Makefile.
