Subject: [Buildroot] [PATCH v2 01/17] arch/arm: introduce and use BR2_ARM_CPU_ARMV7M
Date: Fri, 18 Mar 2016 23:30:50 +0100 [thread overview]
Message-ID: <20160318223050.GB32171@free.fr> (raw)

Thomas, All,
On 2016-03-18 22:08 +0100, Thomas Petazzoni spake thusly:
> All ARM cores should select a BR2_ARM_CPU_* option. Currently, the
> cortex-m3 does not, which this commit fixes by introducing a
> BR2_ARM_CPU_ARMV7M option.
Tangentially related: those options are not user to sepcify iany of the
gcc options, but to allow packages that have CPU-specific code todepend
on it or to enable such support it.
