Is this as-is? If so, we need to figure out something or another to make sharing the code, rather than copying, possible. How are these both grouped in the kernel? Thanks!
Yes, the Snapdragon target uses the identical code. The kernel does not have code for this but rather relies on the bootloader to do it.
