Hi,

This series is two-fold.

 - First some cleanup to nvmem/rmem.

   [PATCH 2/6] nvmem: specify ->reg_read/reg_write() expected return values
   [PATCH 3/6] nvmem: rmem: make ->reg_read() straight forward code
   [PATCH 4/6] nvmem: rmem: remove unused struct rmem::size field

   Those patches were sent on the 2024-07-24 [0] and saw no feedback.
   There are small improvements to the commit messages but the commit
   bodies stayed the same. I did not label this as V2 as the EyeQ5
   compatible (see below) wasn't part of V1, and I wouldn't want people
   to think it has been through a round of lkml review.

 - Second, add a new compatible to rmem for the EyeQ5-specific usecase;
   it parses a header and does checksumming at probe.

   [PATCH 1/6] dt-bindings: nvmem: rmem: Add mobileye,eyeq5-bootloader-config
   [PATCH 5/6] nvmem: rmem: add CRC validation for Mobileye EyeQ5 NVMEM
   [PATCH 6/6] MIPS: mobileye: eyeq5: add bootloader config reserved memory

Code is tested on real hardware, an EyeQ5 evaluation board.

Have a nice day,
Thanks,
Théo
