* Fix SIZE_MAX compiler warning when using stdint.hSimon Glass2014-11-25-0/+2
| | | | | | | This new symbol may be defined by the compiler. If it is, avoid a compiler warning when USE_STDINT is defined. Signed-off-by: Simon Glass <sjg@chromium.org>
* linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-23-13/+4
| | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>
* linux/kernel.h: add typechecking to roundup macroMasahiro Yamada2014-11-20-2/+7
| | | | | | | | | This commit replaces roundup macro with the one from Linux Kernel. DEFINE_ALIGN_BUFFER must be fixed because typechecking can not be used in this context. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* linux/kernel.h: import more macrosMasahiro Yamada2014-11-20-0/+92
| | | | | | | These macros seem to be useful for U-Boot too (or at least harmless). Imported from Linux 3.18-rc2. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* include: move various macros to include/linux/kernel.hMasahiro Yamada2014-11-20-0/+157
U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.
