---help---
This is rptun driver based on pci ivshmem.

config RPTUN_IVSHMEM_NAME
string "rptun ivshmem name"
---help---
Using this config to custom the rptun ivshmem cpuname and role,
using ";" to split the names.
For example, if RPTUN_IVSHMEM_CPUNAME = "0:cpu1:m;1:cpu2:s" and pass
two ivshmem devices to the qemu, we will get two rptun ivshmem
drivers with ivshmem device match id: [0, 1],
remote cpu names: ["cpu1", "cpu2"] and roles: ["master", "slave"']
config RPTUN_IVSHMEM_BUFFSIZE

If TX/RX buffer is supplied and powered by each CPU.
And when one CPU in DEEP sleep, then it's buffer will
goto RAM-retention mode, can't access from another CPU.
So, we provide this method to resolve this.
