From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sonic Zhang Date: Fri, 3 May 2013 18:39:36 +0800 Subject: [Buildroot] [PATCH v7 3/7] arch: toolchain: Introduce target CPU revision. In-Reply-To: <1367577580-3518-1-git-send-email-sonic.adi@gmail.com> References: <1367577580-3518-1-git-send-email-sonic.adi@gmail.com> Message-ID: <1367577580-3518-3-git-send-email-sonic.adi@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: Sonic Zhang Adds the possibility to have a free-form CPU revision string and append it to the target CPU. Only Blackfin actually uses this option. Signed-off-by: Sonic Zhang Acked-by: Thomas Petazzoni --- v6-changes: - The cpu revision test should have a $(call qstrip) to be effective. - Add cpu revision to toolchain/gcc/gcc-uclibc-4.x.mk as well. v3-changes: - Detail the help text and fix the line length. --- arch/Config.in | 3 +++ arch/Config.in.bfin | 8 ++++++++ toolchain/gcc/gcc-uclibc-4.x.mk | 6 +++++- toolchain/toolchain-external/ext-tool.mk | 4 ++++ 4 files changed, 20 insertions(+), 1 deletions(-) diff --git a/arch/Config.in b/arch/Config.in index 27a29c6..175add5 100644 --- a/arch/Config.in +++ b/arch/Config.in @@ -174,6 +174,9 @@ config BR2_GCC_TARGET_ABI config BR2_GCC_TARGET_CPU string +config BR2_GCC_TARGET_CPU_REVISION + string + # Set up target binary format choice prompt "Target Binary Format" diff --git a/arch/Config.in.bfin b/arch/Config.in.bfin index ac96620..f755c8d 100644 --- a/arch/Config.in.bfin +++ b/arch/Config.in.bfin @@ -97,3 +97,11 @@ config BR2_GCC_TARGET_CPU default bf548 if BR2_bf548 default bf549 if BR2_bf549 default bf561 if BR2_bf561 + +config BR2_GCC_TARGET_CPU_REVISION + string "Target CPU revision" + help + Specify a target CPU revision, which will be appended to the + value of the -mcpu option.
