[Qemu-devel] [PATCH for-2.12] hw/arm/bcm2836: Use the Cortex-A7 instead of Cortex-A15

[Peter Maydell]

The BCM2836 uses a Cortex-A7, not a Cortex-A15. Update the device to
use the correct CPU.
https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2836/QA7_rev3.4.pdf

When the BCM2836 was introduced (bad5623690b) the Cortex-A7 was not
available, so the very similar Cortex-A15 was used. Since dcf578ed8ce
we can model the correct core.

This was originally done by a patch from Alistair:
http://lists.nongnu.org/archive/html/qemu-devel/2018-02/msg00311.html

The refactor of bcm2836 means the code is different, but I'm using
the same commit message.
