* sparc: Update PROM initialization code for generic boardFrancois Retief2015-12-03-28/+32
| | | | | | | | | | Fixed the prom_relocate() function in start.S file by reserving memory in the board_init_f sequence and saving the offset to the __prom_start_reloc variable. This value is used as the destination when relocating the PROM. Add the prom_init() function to the end of the board_init_r sequence. Signed-off-by: Francois Retief <fgretief@spaceteq.co.za>

* Replace "extern inline" with "static inline"Måns Rullgård2015-11-09-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of headers define functions as "extern inline" which is causing problems with gcc5. The reason is that starting with version 5.1, gcc defaults to the standard C99 semantics for the inline keyword. Under the traditional GNU inline semantics, an "extern inline" function would never create an external definition, the same as inline *without* extern in C99. In C99, and "extern inline" definition is simply an external definition with an inline hint. In short, the meanings of inline with and without extern are swapped between GNU and C99. The upshot is that all these definitions in header files create an external definition wherever those headers are included, resulting in multiple definition errors at link time. Changing all these functions to "static inline" fixes the problem since this works as desired in all gcc versions. Although the semantics are slightly different (a static inline definition may result in an actual function being emitted), it works as intended in practice. This patch also removes extern prototype declarations for the changed functions where they existed. Signed-off-by: Mans Rullgard <mans@mansr.com>

* arch: Make board selection choices optionalJoe Hershberger2015-05-12-0/+1

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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/.
