[Xen-devel] [PATCH] xen/arm: Add CPU ID for Broadcom Brahma-B15

[marc.ceeeee@xxxxxxxxx]

From: Marc Carino <marc.ceeeee@xxxxxxxxx>

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".
