* bug.h: move BUILD_BUG_* defines to include/linux/bug.hMasahiro Yamada2016-01-25-8/+64
| | | | | | | | | | | | | | | | BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.

* env_mmc: support overriding mmc dev from board codeClemens Gruber2016-01-25-7/+12
| | | | | | | | | | | | | | | | | | | | | | | This enables boards to choose where to/from the environment should be saved/loaded. They can then for example support using the same device (dynamically) from which the bootloader was launched to load and save env data and do not have to define CONFIG_SYS_MMC_ENV_DEV statically. In my use case, the environment needs to be on the same device I booted from. It can be the eMMC or an optional SD card. I therefore would override mmc_get_env_dev in the board code, read the CPU registers to determine where we booted from and return the corresponding device index.

* bootm: fix size arg of flush_cache() in bootm_load_os().Purna Chandra Mandal2016-01-25-1/+1
| | | | | | | | | | | | | | Variable _load_end_ points to end address of uncompressed buffer (*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed size with sizeof(ulong) is grossly incorrect in flush_cache(). It might lead to access of address beyond valid memory range and hang the CPU. Tested on MIPS architecture by using compressed(gzip, lzma) and uncompressed uImage.

We also cannot detect clang after including the arch Makefile, because powerpc wants to know about clang. Solve this by using an deferred variable.

* Move all command code into its own directorySimon Glass2016-01-25-737/+761
| | | | | | | | | | | | | | | | | | | | | | | | | There are a lot of unrelated files in common, including all of the commands. Moving them into their own directory makes them easier to find and is more logical. Some commands include non-command code, such as cmd_scsi.c. This should be sorted out at some point so that the function can be enabled with or without the associated command. Unfortunately, with m68k I get this error: m68k: + M5329AFEE +arch/m68k/cpu/mcf532x/start.o: In function `_start': +arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o I hope someone can shed some light on what this means.
