Subject: [PATCH V4 02/11] arch/csky: Change DSP to VDSP for -mcpu
Date: Fri, 31 May 2019 14:38:59 +0800 [thread overview]
Message-ID: <1559284748-32011-3-git-send-email-guoren@kernel.org> (raw)
In-Reply-To: <1559284748-32011-1-git-send-email-guoren@kernel.org>
From: Guo Ren <ren_guo@c-sky.com>
DSP extention is no longer used for C-SKY gcc and use VDSP instead of
DSP.
VDSP is C-SKY enhanced extension instruction set for SIMD, AI and DSP
operation. It could be supported by abiv2 (ck807, ck810, ck860).
