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.
