* common: Drop init.h from common headerSimon Glass2020-05-181-0/+1

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini2018-04-271-2/+0
| | | | | | | | We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
* arm: mx31: use common timer functionsAndrew Ruder2014-09-161-102/+2
| | | | | | | | | | | | | | | | | | | | This patch moves mx31 to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) mx31 timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locks the processor. Rather than patch the specific mx31 issues, simply move everything over to the common code.

| | | | | | | | | Fix checkpatch warning and errors in several i.MX related files. While at it also address a checkpatch warning at arch/arm/cpu/armv7/mx5/soc.c regarding the usage of extern in a C file. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* MX31: Disable watchdog during low-power modesFabio Estevam2011-09-301-2/+2
| | | | | | | | | | | Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes. Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt and there was no activity, the system entered into idle mode while watchdog timer was still active. Fix this by disabling watchdog timer during idle mode. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* Timer: Remove reset_timer_masked()Graeme Russ2011-07-261-7/+0
| | | | | | | In some circumstances, reset_timer_masked() was called be timer_init() in order to perform architecture specific timer initialisation. In such cases, the required code in reset_timer_masked() has been moved into timer_init()

* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-271-1/+1
| | | | | | | | | | As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.

* MX31: add support for MX31 watchdogStefano Babic2011-04-271-1/+37
| | | | | | | | | | | | | | | | | | The patch add CONFIG_HW_WATCHDOG to be used with the internal watchdog timer of the MX31 processor. Two function are exported for the board maintainers: mxc_hw_watchdog_enable mxc_hw_watchdog_reset The board maintainer can decide to use mxc_hw_watchdog_reset as hw_watchdog_reset, or to implement his own function to reset the watchdog. The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS (value in seconds). The MX31 allows values between 0.5 (CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

* arm1136: timer: Replace bss variable by gdHeiko Schocher2011-02-021-10/+9
| | | | | | | | | | | | | | | | | Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss values in the arm1136 timer driver for mx31 and omap24xx The usage of bss values in drivers before initialisation of bss is forbidden. In that special case some data in .rel.dyn gets corrupted. This patch is similiar to the patch Dirk Behme posted for the armv7/omap-common/timer.c Tested on the mx31 based qong board Signed-off-by: Heiko Schocher <hs@denx.de> cc: Albert ARIBAUD <albert.aribaud@free.fr> Acked-by: Albert ARIBAUD <albert.aribaud@free.fr>
