From: Yann E. MORIN Date: Tue, 14 Mar 2017 18:30:31 +0000 (-0700) Subject: arch/xtensa: add definitions for the Xtensa overlay X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bcecbed654c517cf9349c7e108d014a0831d3aed;p=buildroot.git arch/xtensa: add definitions for the Xtensa overlay Currently, we have four packages that need to use the Xtensa overlay: binutils, gcc-initial, gcc-final and gdb. However, they all use three different ways to check for, and use the overlay. Furthermore, two of them define the same variable: XTENSA_CORE_NAME is defined both by binutils and gdb In order to sanitise that, have the Xtensa architecture export the appropriate variables: the name of the core and the path to the overlay tarball. Packages can then check and use those variables. Signed-off-by: "Yann E.
