ARM: Default to using optimized memset and memcpy routines

2017-01-20T20:38:01Z

We have long had available optimized versions of the memset and memcpy functions that are borrowed from the Linux kernel. We should use these in normal conditions as the speed wins in many workflows outweigh the relatively minor size increase. However, we have a number of places where we're simply too close to size limits in SPL and must be able to make the size vs performance trade-off in those cases.

armv8: prevent using THUMB

2017-01-04T15:37:40Z

The predominantely 32-bit ARM targets try to compile the SPL in Thumb mode to reduce code size. The 64-bit AArch64 instruction set does not know an alternative, concise encoding, so the Thumb build option should only be set for 32-bit targets. Likewise -marm machine options are only valid for ARMv7 targets.

efi_loader: Allow to compile helloworld.efi w/o bundling it

2016-11-27T14:53:39Z

Today we can compile a self-contained hello world efi test binary that allows us to quickly verify whether the EFI loader framwork works. We can use that binary outside of the self-contained test case though, by providing it to a to-be-tested system via tftp. This patch separates compilation of the helloworld.efi file from including it in the u-boot binary for "bootefi hello". It also modifies the efi_loader test case to enable travis to pick up the compiled file. Because we're now no longer bloating the resulting u-boot binary, we can enable compilation always, giving us good travis test coverage. Signed-off-by: Alexander Graf Reviewed-by: Tom Rini

cmd: Split 'bootz' and 'booti' out from 'bootm'

2016-08-20T15:35:07Z

The bootz and booti commands rely on common functionality that is found in common/bootm.c and common/bootm_os.c. They do not however rely on the rest of cmd/bootm.c to be implemented so split them into their own files. Have various Makefiles include the required infrastructure for CONFIG_CMD_BOOT[IZ] as well as CONFIG_CMD_BOOTM. Move the declaration of 'images' over to common/bootm.c.

ARM: Rework and correct barrier definitions

2016-08-05T11:23:57Z

As part of testing booting Linux kernels on Rockchip devices, it was discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for some cases incomplete isb definitions. This was causing a failure to boot of the Linux kernel. In order to solve this problem as well as cover any corner cases that we may also have had a number of changes are made in order to consolidate things. First, now becomes the source of isb/dsb/dmb definitions. This however introduces another complexity. Due to needing to build SPL for 32bit tegra with -march=armv4 we need to borrow the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete form. Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add a comment about it. Now that we can always know what the target CPU is capable off we can get always do the correct thing for the barrier. The final part of this is that need to be consistent everywhere and call isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the function names in others.

arm: lib: import muldi3.S from Linux

Import muldi3.S from Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 on arm32. This file implements __aeabi_lmul and it's alias __muldi3, which is needed when doing Thumb1 builds. This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED which is necessary for correct build of these files both in ARM and Thumb mode, just like Linux does.

arm: lib: Import __do_div64 from Linux

Import __do_div64 from Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 on arm32. This function is for some toolchains, which generate _udivmoddi4() for 64 bit division. Since we do not support stack unwinding, instead of importing the whole asm/unwind.h and all the baggage, this patch defines empty UNWIND() macro. This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED which is necessary for correct build of these files both in ARM and Thumb mode, just like Linux does.
