efi_selftest: allow building on ARMv7-M

2019-02-13T08:40:05Z

ARMv7-M only supports the Thumb instruction set. Our current crt0 code does not support it. With the patch we can build all unit tests of the EFI subsystem that do not require crt0. Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

arm: v7: Kconfig: Introduce SYS_ARM_CACHE_CP15

2018-05-07T19:53:28Z

Certain ARM architectures like ARMv7-A, ARMv7-R has support for enabling caches using CP15 registers. To have a common support for all these architectures, introduce a Kconfig symbol SYS_ARM_CACHE_CP15 that selects cache-cp15.c Tested-by: Michal Simek Reviewed-by: Tom Rini Signed-off-by: Lokesh Vutla

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: Fix Makefile during SPL and TPL build

2018-04-11T17:22:06Z

The tiny variants of memset and memcpy implementations can be built for TPL as well, check whether a TPL build is in progress and avoid including the default variants. Signed-off-by: Marek Vasut Cc: Simon Glass Cc: Tom Rini

move booti_setup to arch/arm/lig/image.c

2018-02-08T03:06:11Z

Follow bootz's pattern by moving the booti_setup to arch/arm/lib. This allows to use booti_setup in other paths, e.g booting an Android image containing Image format. Note that kernel relocation is move out of booti_setup and it is the caller's responsibility to do it and allows them do it differently. say, cmd/booti.c just do a manually, while in the bootm path, we can use bootm_load_os(with some changes).

efi_selftest: test start image

2018-01-22T22:09:14Z

This pair of tests checks the StartImage boot service. Each test loads an EFI application into memory and starts it. One returns by calling the Exit boot service. The other returns directly. The tests are not built on x86_64 because the relocation code for the efi binary cannot be created. Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

arm: provide a PCS-compliant setjmp implementation

2017-11-21T22:57:22Z

The previous setjmp-implementation (as a static inline function that contained an 'asm volatile' sequence) was extremely fragile: (some versions of) GCC optimised the set of registers. One critical example was the removal of 'r9' from the clobber list, if -ffixed-reg9 was supplied. To increase robustness and ensure PCS-compliant behaviour, the setjmp and longjmp implementation are now in assembly and closely match what one would expect to find in a libc implementation.

arm: Add Kconfig symbols used for Linux asm compatibility

2017-06-05T18:13:13Z

Rather than change asm files that come from Linux, add the symbols to Kconfig. Since one of the symbols is for thumb2 builds, make CPU_V7M always select them. Signed-off-by: Phil Edworthy

armv8: fsl: move ccn504 code into FSL Makefile

2017-05-17T17:50:50Z

The generic ARMv8 assembly code contains routines for setting up a CCN interconnect, though the Freescale SoCs are the only user. Link this code only for Freescale targets, this saves some precious bytes in the chronically tight SPL. Signed-off-by: Andre Przywara

armv8: SPL: only compile GIC code if needed

2017-05-17T17:50:31Z

Not every SoC needs to set up the GIC interrupt controller, so link think code only when the respective config option is set. This shaves off some bytes from the SPL code size. Signed-off-by: Andre Przywara Reviewed-by: Simon Glass Reviewed-by: Jagan Teki
