common: Move interrupt functions into a new header

2019-12-02T23:25:00Z

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 Reviewed-by: Tom Rini

We should not include the same include twice. Fixes: 99b8db7291ce ("arm: print information about loaded UEFI images") Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

arm: print instructions pointed to by pc

2018-05-24T02:06:41Z

If an exception occurs in a loaded image and the relocation offset is unknown, it is helful to know the instructions pointed to by the program counter. This patch adds the missing output. A possible output is: Code: e1c560d0 e12fff1e e120077b e12fff1e (e7f7defb) The parentheses indicate the instruction causing the exception. The output can be disassembled using the decodecode script provided by the Linux kernel project. Signed-off-by: Heinrich Schuchardt

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

arm: print information about loaded UEFI images

2018-04-05T13:24:01Z

If an exception occurs in a UEFI loaded image we need the start address of the image to determine the relocation offset. This patch adds the necessary lines after the registers in the crash dump. A possible output would be: UEFI image [0xbffe6000:0xbffe631f] pc=0x138 '/\snp.efi' With the offset 0x138 we can now find the relevant instruction in the disassembled 'snp.efi' binary.

arm: adjust PC displayed in exception handlers to point to the failing instruction

2017-06-12T12:38:39Z

Adjust the program counter register to point to the failing instruction depending on the exeption type. This makes it easier to localize the offending instruction leading to a fatal exception. Signed-off-by: Lothar Waßmann

Remove various unused interrupt related code

2017-04-07T00:42:18Z

With d53ecad92f06 some unused interrupt related code was removed. However all of these options are currently unused. Rather than migrate some of these options to Kconfig we just remove the code in question. The only related code changes here are that in some cases we use CONFIG_STACKSIZE in non-IRQ related context. In these cases we rename and move the value local to the code in question. Fixes: d53ecad92f06 ("Merge branch 'master' of git://git.denx.de/u-boot-sunxi") Signed-off-by: Tom Rini

arm: Allow EFI payload code to take exceptions

2016-03-16T01:30:13Z

There are 2 ways an EFI payload could return into u-boot: - Callback function - Exception While in EFI payload mode, r9 is owned by the payload and may not contain a valid pointer to gd, so we need to fix it up. We do that properly for the payload to callback path already. This patch also adds gd pointer restoral for the exception path. Signed-off-by: Alexander Graf
