Dear all, As we know dcache is now enabled in u-boot.
I'm trying to make the S5P Goni target working with d-cache enabled. There are some patches and ideas appearing on the list (e.g. http://patchwork.ozlabs.org/patch/109199/ made by Aneesh V) I'm currently using the u-boot/master branch, SHA1: d26a82023af5771462f7223241ed18cfb7965f71 After some research I can say that flush_dcache_all() and invalidate_dcache_all() are working(at least on my target). However I'm planning to use the "range" versions: flush_dcache_range((unsigned long) (buf), sizeof(buf)); invalidate_dcache_range((unsigned long) (buf), sizeof(buf)); Those versions are not working on the Cortex-A8 (armv7) GONI target. I'd like to ask if anybody was trying to use those functions (defined at cache_v7.c) on other armv7 targets? I think that only flush or invalidation on the selective cache regions are the way to go. The "*_dcache_all()" methods seems like an overkill. -- Best regards, Lukasz Majewski Samsung Poland R&D Center Platform Group _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
