From dc3946ac37e0c7aed74b0041f742a102d37af425 Mon Sep 17 00:00:00 2001

Subject: [PATCH 147/148] Revert "firmware: bcm2835: Support legacy mailbox
API"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This reverts commit 40aa3c4f0c430cd5c574498f4d1d5e9f0bc1cf11.
The legacy mailbox API has been removed so this is not needed.
