2019-12-02common: Move interrupt functions into a new headerSimon Glass
These functions do not use driver model but are fairly widely used in U-Boot. But it is not clear that they will use driver model anytime soon, so we don't want to label them as 'legacy'. Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it is widely used in U-Boot already. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2018-12-10x86: Wrap calls to 8259 with CONFIG_I8259_PICBin Meng
mask_irq(), unmask_irq() and specific_eoi() are provided by the i8259 PIC driver and should be wrapped with CONFIG_I8259_PIC. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Hannes Schmelzer <oe5hpm@oevsv.at>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

2015-11-13x86: Rename CONFIG_SYS_NUM_IRQS to SYS_NUM_IRQSBin Meng
CONFIG_SYS_NUM_IRQS is actually not something we can configure, but an architecture defined number of ISA IRQs. Move it from x86-common.h to asm/interrupt.h and rename it to SYS_NUM_IRQS. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
