From eed0eabd12ef061821cbfa20d903476e07645320 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 5 Oct 2016 18:18:20 +0100 Subject: MIPS: generic: Introduce generic DT-based board support Introduce a "generic" platform, which aims to be board-agnostic by making use of device trees passed by the boot protocol defined in the MIPS UHI (Universal Hosting Interface) specification. Provision is made for supporting boards which use a legacy boot protocol that can't be changed, but adding support for such boards or any others is left to followon patches. Right now the built kernels expect to be loaded to 0x80100000, ie. in kseg0. This is fine for the vast majority of MIPS platforms, but nevertheless it would be good to remove this limitation in the future by mapping the kernel via the TLB such that it can be loaded anywhere & map itself appropriately. Configuration is handled by dynamically generating configs using scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc makes use of it. This allows for variations upon the configuration, eg. differing architecture revisions or subsets of driver support for differing boards, to be handled without having a large number of defconfig files.
