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 on a dedicated messaging unit(MU)
based interface(s) with application core, where kernel is running.
It exists on specific i.MX processors. e.g. i.MX8ULP, i.MX93.
This patch adds the driver for communication interface to secure-enclave,
for exchanging messages with NXP secure enclave HW IP(s) like EdgeLock
Enclave (ELE) from Kernel-space, used by kernel management layers like
- DM-Crypt.

When running below low power case on 8ULP dual boot, we meet Linux fail to
restore ELE imem from file
APD: Linux boot, then “poweroff” to DPD.
RTD: After linux “poweroff”, enter DPD and wake up by timer (G+T+2)
then enter PD and wake up by timer (F+T+2), wake up APD (W).
The root cause is when RTD is waken up from DPD, it is booted from ROM,
and ROM reloads the ELE FW and RTD image. Then when RTD is waken up from PD
and wake up APD, APD will try to restore the ELE imem which was saved
before ELE FW reloading. So this imem restore is failed.
To avoid moving ELE imem save/restore to M33, because of RAM size problem
and big codes change. The proposed solution is replacing the imem restore
from file with re-install ELE FW. This patch needs to work with ELE FW
which supports the re-install feature.

To support iMX93 GDET enabled part, it needs to isolate GDET when VDD_SOC
changing between OD and LD. ELE introduces two new APIs: voltage start and
finish for this purpose.
Voltage change start:
- This command isolates GDET and launches a 5 ms timer.
During the 5 ms, the voltage needs to be changed and voltage change
finish command must be called to remove GDET isolation (no other command
will be accepted). A GDET software reset is done before removing the
isolation in voltage change finish.
Voltage change finish:
- This command can’t be called without voltage change start.
To support above commands, especailly no other command will be accepted
after voltage change start issued, so adjust the mu_cmd_lock to each
command begin, this also resolves potential issue in imx_se_alloc_tx_rx_buf
since the buf pointer is not locked.

When RTD is power down, 64kB over the 96kB of ELE FW RAM are lost and
must be restored at resume. However when kernel (APD) is poweroff,
current implementation does not restore the ELE RAM, so cause failure

To fix the issue, this patch checks the iMEM state from ELE get info API
to determine loading extend FW or restore iMEM. It also saves ELE iMEM RAM
to file on rootfs at ELE driver probe and resume.
