-Subject: [PATCH 003/222] mailbox: bcm2708: Add bcm2708-vcio
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Signed-off-by: popcornmix <popcornmix@gmail.com>
-
-Copy the arch vcio.c driver to drivers/mailbox.
-This is done to make it available on ARCH_BCM2835.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-mailbox: bcm2708-vcio: Allocation does not need to be atomic
-
-No need to do atomic allocation in a context that can sleep.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-mailbox: bcm2708-vcio: Check the correct status register before writing
-
-With the VC reader blocked and the ARM writing, MAIL0_STA reads
-empty permanently while MAIL1_STA goes from empty (0x40000000)
-to non-empty (0x00000001-0x00000007) to full (0x80000008).
