this series looks ok to me on top of master-next.

From: Mark Hatle <mark.hatle@amd.com> cortexa78 missing seems to be an oversight. It (according to wikipedia) is a successor to the cortexa77 which already exists. This was created by copying the cortexa77 and changing it to be a78. A test system was build to verify no obvious issues with the toolchain. The remaining three changes are related. I've got a need for a cortex-r5 and cortex-r52 that enables the hard-float calling convention (this might also be useful to others with other cortex-r and maybe even cortex-m processors, but I'm not in a position to know this outside of my specific need.) tune-cortexr5 simply adds an hf variant that adds the callconvention-hard. Since there is no armv7r-vfp3d16 w/ this, the package_arch list is more limited then the regular r5. tune-cortexr52 requires the change to feature-arm-vfp to allow the setting when 'simd' is enabled (since we don't specify vfp or neon). Otherwise this follows the same convention as the r5 change. v2: Rebase cortex-a78 tune based on current master-next branch. THis addresses Khem's comment. Mark Hatle (4): tune-cortexa78.inc: Add cortexa78 tune, based on cortexa77 feature-arm-vfp.inc: Allow hard-float on newer simd targets tune-cortexr5: Add hard-float variant tune-cortexr52: Add hard-float variant .../include/arm/armv7r/tune-cortexr5.inc | 5 +++++ .../include/arm/armv8-2a/tune-cortexa78.inc | 17 +++++++++++++++++ .../include/arm/armv8r/tune-cortexr52.inc | 5 +++++ .../machine/include/arm/feature-arm-vfp.inc | 3 ++- 4 files changed, 29 insertions(+), 1 deletion(-) create mode 100644 meta/conf/machine/include/arm/armv8-2a/tune-cortexa78.inc
