From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann E. MORIN Date: Thu, 5 Apr 2018 22:39:34 +0200 Subject: [Buildroot] [PATCH 03/23] arch: remove Blackfin architecture In-Reply-To: <20180405195037.32641-4-thomas.petazzoni@bootlin.com> References: <20180405195037.32641-1-thomas.petazzoni@bootlin.com> <20180405195037.32641-4-thomas.petazzoni@bootlin.com> Message-ID: <20180405203934.GC22364@scaer> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Thomas, All, On 2018-04-05 21:50 +0200, Thomas Petazzoni spake thusly: > The Blackfin architecture has for a long time been complicated to > maintain, with poor support in upstream binutils/gcc. As of April > 2018, the Blackfin architecture has been dropped from the upstream > Linux kernel. Also, the Analog Device engineer who used to be in touch > with the Buildroot community also privately said we should drop the > support for this architecture, which Analog Devices is no longer > using, promoting and maintaining. > > The BR2_BINFMT_FLAT_SEP_DATA option becomes unselectable, it will be > removed in a future commit. > > Signed-off-by: Thomas Petazzoni Reviewed-by: "Yann E.
