From e65a173e5243bb9fdecc4e1792e473116d1de9ef Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Thu, 20 Jun 2019 12:07:23 +0200 Subject: [PATCH] arch/arm: add two new cortex-based armv8.2a cores The cortex-a76 implements the full amrv8.2a extensions, and some optional extensions from the armv8.3a, armv8.4a, and armv8.5a sets, but none of their mandatory extensions, which means that it does not qualify for better than an armv8.2a: https://developer.arm.com/products/processors/cortex-a/cortex-a76 http://infocenter.arm.com/help/topic/com.arm.doc.100798_0301_00_en/giq1479805174793.html http://infocenter.arm.com/help/topic/com.arm.doc.100798_0301_00_en/fjv1477559794375.html Also, gcc fits it in the armv8.2a category, too: https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/aarch64/aarch64-cores.def;h=67ce42fb8aacd4c246295f32151a03b1f318ae44;hb=HEAD#l97 Build tested: https://gitlab.com/kubu93/buildroot/pipelines/60318953 Signed-off-by: "Yann E.
