So you're saying that if we allow 32-bit address spacing for a particular board, then we must provide a 32-bit DTS to go with it? I was hoping to use the defconfig to force 36-bit, so that we can have a 32-bit option if we want. Just because we don't put a 32-bit DTS in the upstream kernel, that doesn't mean that no one is allowed to have a 32-bit kernel. > What's wrong with the current scheme ? It prevents the possibility of creating an "optimized" 32-bit address environment, for people who have <= 2GB of DDR on the board. If we want to ship a 32-bit DTS and 32-bit U-Boot on our BSP, then we'll need to patch the Kconfig to remove the "select" line. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
