2018-06-14efi_loader: Convert runtime reset from switch to if statementsAlexander Graf
We currently handle the UEFI runtime reset / power off case handling via a switch statement. Compilers (gcc in my case) may opt to handle these via jump tables which they may conveniently put into .rodata which is not part of the runtime section, so it will be unreachable when executed. Fix this by just converting the switch statement into an if/else statement. It produces smaller code that is faster and also correct because we no longer refer .rodata from efi runtime code.

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>
2018-04-04efi_loader: add missing EFI_RESET_PLATFORM_SPECIFICHeinrich Schuchardt
EFI_RESET_PLATFORM_SPECIFIC is one of the values that can be used for the EFI service ResetSystem. The missing definition is added. The value has to handled in efi_reset_system(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-04-04efi_loader: exit status for efi_reset_system_initHeinrich Schuchardt
efi_reset_system_init provides the architecture or board specific initialization of the EFI subsystem. Errors should be caught and signalled by a return code. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2016-11-28ARM: bcm283x: Implement EFI RTS reset_systemAlexander Graf
The rpi has a pretty simple way of resetting the whole system. All it takes is to poke a few registers at a well defined location in MMIO space. This patch adds support for the EFI loader implementation to allow an OS to reset and power off the system when we're outside of boot time. Signed-off-by: Alexander Graf <agraf@suse.de>
2016-01-19Add more SPDX-License-Identifier tagsTom Rini
In a number of places we had wordings of the GPL (or LGPL in a few cases) license text that were split in such a way that it wasn't caught previously. Convert all of these to the correct SPDX-License-Identifier tag. Signed-off-by: Tom Rini <trini@konsulko.com>
2015-03-28ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283xMasahiro Yamada
BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2) are similar enough. One of the biggest differences is the ARM processor. It is reasonable to collect the source files into a single place, arch/arm/mach-bcm283x/.
