I don't know if my memory serves me right but there was a discussion
a while back about the OMAP mailboxes and whether they needed a
subsystem on their own.

(I cannot find it now...)

Either the conclusion was "we should look into it sometime" or
"too little code to worry about".

I even have a vague memory of someone proposing drivers/mailbox
for OMAP once, but might not remember correctly.

Ohad/Tony probably knows...

Candidates would be:

arch/arm/plat-omap/mailbox.c
arch/arm/mach-omap1/mailbox.c
arch/arm/mach-omap2/mailbox.c
arch/arm/mach-ux500/mbox-db5500.c
Portions of: drivers/mfd/db8500-prcmu.c
+ some new code I think Sjur Brændeland have cooking for
drivers/modem-shm
