The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.
The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).
As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
and private header files. The public header has only the API related
functions and types.
- The module name mailbox.ko from plat-omap is changed to
omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
mailbox_omap1.ko for OMAP1
mailbox_omap2.ko for OMAP2+
