-The current fixed physical/virtual mappings for the internal peripherals
-of the ixp4xx SoC devices is using a virtual address outside of the vmalloc
-region. This results in kernel warnings like this on the boot console:
-
- BUG: mapping for 0xc8000000 at 0xffbeb000 out of vmalloc space
- BUG: mapping for 0xc4000000 at 0xffbfe000 out of vmalloc space
- BUG: mapping for 0xc0000000 at 0xffbff000 out of vmalloc space
-
-The virtual kernel memory layout lists this for the vmalloc region:
-
- ...
- vmalloc : 0xc2800000 - 0xff000000 ( 968 MB)
- ...
-
-With a little adjustment to the virtual address used we can map these
-internal devices in the vmalloc region.
