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.
>
