Authoring Linux Subsystems

We authored several Linux Kernel subsystems such as: rpmsg and remoteproc, as well as the hardware spinlock subsystem.

Rpmsg was adopted by many CPU vendors, including Texas Instruments, STMicroelectronics, Xilinx, NXP Semiconductors, Renesas Electronics and Nordic Semiconductor, and was ported even for non-Linux environments. For more info, see this Wikipedia page: https://en.wikipedia.org/wiki/RPMsg
