[PATCH 05/10] hw/hppa: Fix firmware end address for LASI chip

Posted by deller@kernel.org 3 weeks, 6 days ago

From: Helge Deller <deller@gmx.de>

The base address of a LASI chip on a 715 machine starts at HPA
0xf0100000.  Make sure that the firmware does not extend beyond that
address, otherwise it's not possible to access the LASI ports.
