Not really - I think you have to dig into the git history, when we could skip relocation via a CONFIG_ OPTION. Maybe someone else can give some more hints. Anyway, nobody nowadays checks if a patch breaks when the relocation is skipped, as this option is unsupported, and the possibility that your implementation will be break by next update is quite high... >> As your concerns are surely related to speed up the boot process, IMHO >> we can focus efforts to add cache support for MX5 / MX6. > > Ok, sounds good. Any idea what has to be done for this? Or what would be > the steps for this? As armv7 architecture, the MX can profit of the work already done for other SOCs. Functions for enabling / disabling / invalidate caches are already provided, in arch/arm/lib and arch/arm/cpu/armv7/cache_v7.c. So at least for MX5/MX6. But we should change MXC drivers to be cache-aware. At least the FEC driver and MMC driver are known to not work when dcache is on. > Maybe we should open a new thread or at least rename > the subject of this mail for this discussion? Not a bad idea.
