build meta-zephyr or prebuild image

[Vince Chang]

Dear OpenBMC org,

The next generation ASPEED BMC AST2700 will integrate a RISC-V MCU (BootMCU) as the first stage bootloader, and the firmware will be written with Zephyr RTOS.
We'd like to seek your guidance on the best approach for this integration.
I am considering two options:


  1.  Using a prebuilt image:
This approach would use a prebuilt image in the build process, which is simple. However, I am concerned about the flexibility and customization options that might be limited with this approach.


  1.  Adding the meta-zephyr layer:
This approach would involve adding meta-zephyr. I am considering using "git subtree add meta-zephyr" to integrate it into OpenBMC.

Thanks,
