[PATCH] xen: arm: Add CPU ID for Broadcom Brahma-B15
From: Marc Carino <marc.ceeeee@gmail.com>
Let Xen recognize the Broadcom Brahma-B15 CPU by adding the appropriate
MIDR mask to the initialization phase. Further, ensure that the console
output properly reports the CPU manufacturer as "Broadcom
Corporation".
