[PATCH v4 0/7] firmware: imx: NXP Edgelock Enclave MUAP Driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



v4 Changes:
- Post internal review, changed the name from "ele-mu" to "se-fw".
- Disposed-off comments in the dt-binding file.
- Removed the non-hw related dt-bindings from the driver code.
- Corrected the File MAINTAINERS for correct name of yaml file.

v3 Changes:
- update the commit message for documentation.
- Fixed dt-binding checking error for file- fsl,ele_mu.yaml
- Coverity fixes in the ele_mu.c

v2 Changes:

- Fixed Kernel Test Bot issues.
- Removed ".../devicetree/bindings/mailbox/fsl,muap.txt"

v1:

The Messaging Unit module enables two processing elements within the SoC to
communicate and coordinate by passing messages (e.g., data, status and control)
through its interfaces.

The NXP i.MX EdgeLock Enclave Message Unit (ELE-MUAP) is specifically targeted
for use between application core and Edgelocke Enclave. It allows to send
messages to the EL Enclave using a shared mailbox.

Patch-set add the ELE-MU  kernel driver for exchanging messages with i.MX NXP
ELE IP; both from:
- User-Space Applications via character driver.
- Kernel-space, used by kernel management layers like DM-Crypt.
