SPDX: Convert all of our single license tags to Linux Kernel style 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> 2018-05-06 21:58:06 +00:00			`// SPDX-License-Identifier: GPL-2.0+`

arm: pxa: use common timer functions This patch moves pxa to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) pxa 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 locked the processor. Rather than patch the specific pxa issues, simply move everything over to the common code.

arm: timer and interrupt init rework actually the timer init use the interrupt_init as init callback which make the interrupt and timer implementation difficult to follow so now rename it as int timer_init(void) and use interrupt_init for interrupt btw also remane the corresponding file to the functionnality implemented as ixp arch implement two timer - one based on interrupt - so all the timer related code is moved to timer.c Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> 2009-05-15 21:47:02 +00:00			`return 0;`
