From: Thomas De Schampheleire Date: Wed, 30 Jan 2019 20:12:24 +0000 (+0100) Subject: arch/mips: add (Marvell) Octeon III processor X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=18b8d360bb920c415fb875f721ecae886c316db9;p=buildroot.git arch/mips: add (Marvell) Octeon III processor The compiler recognizes a specific 'march' value for Octeon III processors, so create a 'Target Architecture Variant' entry for it in the target menu. Note: support for '-march=octeon3' was added in gcc 5.x. However, the official compiler provided by Marvell (Cavium Networks) uses gcc 4.7.x (and supports -march=octeon3 via their own modifications). For this reason, no line 'select BR2_ARCH_NEEDS_GCC_AT_LEAST_5' is added.
