* microblaze: Fix C99/gnu99 compatiblity for inline functionsNathan Rossi2015-11-19-43/+22
| | | | | | | | | | | | | | | | | 'extern inline' is not portable across various C standards. To ensure compatiblity with various standards/compilers change the functions to static inline. This is a portable construct and serves as a comparable definition to 'extern inline' from the gnu90 standard. Additionally remove the function prototypes as they are not required due to the functions being declared static and functions are correctly ordered based on dependence.

* Various Makefiles: Add SPDX-License-Identifier tagsTom Rini2015-11-10-0/+4
| | | | | | | | | | | After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.

* arch: Make board selection choices optionalJoe Hershberger2015-05-12-0/+1
| | | | | | | | | | | | By making the board selections optional, every defconfig will include the board selection when running savedefconfig so if a new board is added to the top of the list of choices the former top's defconfig will still be correct.

* generic-board: select SYS_GENERIC_BOARD for some architecturesMasahiro Yamada2015-03-28-1/+0
| | | | | | | | | | | | We have done with the generic board conversion for all the boards of ARC, Blackfin, M68000, MicroBlaze, MIPS, NIOS2, Sandbox, X86. Let's select SYS_GENERIC_BOARD for those architectures, so we can tell which architecture has finished the conversion at a glance.

* Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck2014-12-08-0/+8
| | | | | | | | | | | | | | | Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* dts: move device tree sources to arch/$(ARCH)/dts/Masahiro Yamada2014-02-19-0/+7
| | | | | | | | | | | | | | | | | Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
