2018-12-05Add UINT32_MAX and UINT64_MAXSimon Glass
These constants are defined by stdint.h but not by kernel.h, which is its stand-in in U-Boot. Add the definitions so that libraries which expect stdint.h constants can work. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-01-10linux/kernel.h: Add ALIGN_DOWN macroMasahiro Yamada
Follow Linux commit ed067d4a859f ("linux/kernel.h: Add ALIGN_DOWN macro"). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-10-05linux/kernel.h: import DIV_ROUND_{DOWN, UP}_ULL from LinuxMasahiro Yamada
These macros are useful to avoid link error on 32-bit systems. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2014-11-25Fix SIZE_MAX compiler warning when using stdint.hSimon Glass
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>
2014-11-23linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada
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>
2014-11-20linux/kernel.h: add typechecking to roundup macroMasahiro Yamada
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>
2014-11-20linux/kernel.h: import more macrosMasahiro Yamada
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>
2014-11-20include: move various macros to include/linux/kernel.hMasahiro Yamada
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.
