mailbox/omap: move the OMAP mailbox framework to drivers
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+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>
