firmware: imx: add driver for NXP EdgeLock Enclave
Add MU-based communication interface for secure enclave.
NXP hardware IP(s) for secure-enclaves like Edgelock Enclave(ELE), are
embedded in the SoC to support the features like HSM, SHE & V2X, using
message based communication interface.
The secure enclave FW communicates with Linux over single or multiple
dedicated messaging unit(MU) based interface(s).
Exists on i.MX SoC(s) like i.MX8ULP, i.MX93, i.MX95 etc.
For i.MX9x SoC(s) there is at least one dedicated ELE MU(s) for each
world - Linux(one or more) and OPTEE-OS (one or more).
Other dependent kernel drivers will be:
- NVMEM: that supports non-volatile devices like EFUSES,
managed by NXP's secure-enclave.
