* include: move panic() prototype to <printk.h>Ahmad Fatoum2022-10-051-2/+0
| | | | | | | | | | | | The panic declaration in <linux/kernel.h> is out of place and unexpected as it's not a Linux kernel. printf() and printk() are defined in <printk.h>, so move it there too. Most files making use of panic(), pull it in via <common.h>, so we only need to adjust two headers for the new location.

* include: move ARRAY_AND_SIZE to <linux/kernel.h>Ahmad Fatoum2021-11-011-0/+1
| | | | | | | | | | Linux defines this macro at multiple places. We define it once, but in <common.h>, which is a bit heavy weight. Move it next to the ARRAY_SIZE() definition.

* treewide: include <linux/math64.h> wrapper instead of <asm-generic/div64.h>Ahmad Fatoum2021-02-191-1/+1
| | | | | | | | | | | <asm-generic/div64.h> isn't meant for direct usage as <asm/div64.h> may override this on a per-architecture basis. We don't do that currently, but in the future we might. Include the <linux/math64.h> instead. No functional change. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | Copy include/linux/limits.h from Linux 5.1-rc1 (removing #include <uapi/linux/limits.h>). While we are here, add SPDX License tag to <linux/kernel.h>. Based on the following Linux commits: - 54d50897d544 ("linux/kernel.h: split *_MAX and *_MIN macros into <linux/limits.h>") - 2dc0e68d5ada ("linux/kernel.h: use 'short' to define USHRT_MAX, SHRT_MAX, SHRT_MIN") Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* linux/kernel.h: move some macros and prototypesMasahiro Yamada2015-01-291-0/+61
| | | | | | | | | | The include/common.h is still cluttered (although much better than U-Boot). It contains various utility macros that originates in Linux. Move them to the original place, include/linux/kernel.h, to slim down include/common.h. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | Linux uses SHRT_* instead of SHORT_*. The <limits.h> of C does the same. Let's follow this standard. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* linux/kernel.h: move *_MAX, *_MIN macrosMasahiro Yamada2015-01-211-0/+13
| | | | | | | | | | | Linux defines *_MAX, *_MIN macros in include/linux/kernel.h. Let's follow this way to slim down the common.h. This change should have no impact because include/common.h already includes <linux/kernel.h>.

| | | | | | | | | | | | | | | | | | EHCI HCD has a private version of min3() determining the smallest number out of 3.

| |/ | | | | | | | | | | | | | | | | Yes, we already have roundup/rounddown. Unlike these macros round_up/round_down are optimized to (and only work with) power-of-2 arguments.
