menuconfig RT_USING_MBOX
bool "Using Hardware Mailbox device drivers"
depends on RT_USING_DM
depends on RT_USING_OFW
default n
help
Enable the mailbox framework so multi-core SoCs or remote processors can
exchange messages via hardware mailbox/FIFO IP. The core registers mailbox
controllers described in device tree, manages channel timeouts, and
exposes asynchronous send/receive callbacks to drivers such as RPMsg or
audio DSP clients. Disable it only when the SoC lacks mailbox hardware.
config RT_MBOX_PIC
bool "RT-Thread PIC Mailbox"
depends on RT_USING_MBOX
default y
help
Build the PIC mailbox controller driver which exposes RT-Thread's
platform interrupt controller mailboxes through the common API. Select it
when the firmware runs on platforms where the PIC provides mailbox
registers (for example Sophgo SG2042); turning it off prevents those DTS
nodes from binding.
