We can build the openamp library configured with VirtIO master
support, VirtIO slave support, or both. By default both master
and slave code is enabled. We can reduce code footprint by only
build master or slave as needed.
Expose Kconfig options for Master & Slave and set them accordingly in
the sample.
Here's the code reduction we see:
For the total image we see as 1260 byte reduction:
Memory region Used Size Region Size %age Used
FLASH [Master & Slave]: 30308 B 256 KB 11.56%
FLASH [Master only] : 29048 B 256 KB 11.08%
On the remote side we see a 828 byte reduction:
Memory region Used Size Region Size %age Used
FLASH [Master & Slave]: 11564 B 64 KB 17.65%
FLASH [Slave only] : 10736 B 64 KB 16.38%

The v2018.10 release of OpenAMP reworks the API set and splits the
remoteproc vs rpmsg interfaces so one can use rpmsg without remoteproc.
This helps drastically reduce the code footprint utilized by OpenAMP.
The remote see around 4k reduction in code size.

With recent changes to open-amp we can now include and build it directly
as a zephyr library rather than doing a recursive make. We remove
ext/lib/ipc/open-amp.cmake as part of this change and introduce a
Kconfig option for open-amp.
Fixes: #7673

With recent changes to libmetal we can now include and build it directly
as a zephyr library rather than doing a recursive make. We remove
ext/hal/libmetal.cmake as part of this change and introduce a Kconfig
option for libmetal.
This is a partial fix for issue #7673.

This commit adds a sample application using OpenAMP for remote procedure
calls on the LPCXpresso54114. It is adapted from the RPMsg-Lite sample
application added in PR #5960, and uses the IPM driver to provide
interprocessor interrupts.
