    mailbox/omap: move the OMAP mailbox framework to drivers · c869c75c
    Suman Anna authored
    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+
