Hi, the build instructions on branch `fwk-hx20-hx30-4410` don't work for the `fwk-sunflower-26784` (FW12) branch because the build system appears to be very different. I've tried following the routine of the GitHub Actions workflow used to build `sunflower-3.0.4-fa46a90` (on commit `fa46a90`) but I eventually fail with some strange Kconfig errors that I don't know how to interpret (attached below). According to a [post](https://community.frame.work/t/open-source-ec-for-amd-based-13-16/33923) on the Framework Community Forum, the issue appears to be that Framework uses a custom Zephyr version that mismatches... something... that makes the build fail. I tried to build on a Ubuntu 24.04 x86 VM. I'm not experienced with GitHub Actions or EC build systems at all so I asked ChatGPT on how I should replicate the workflow on my VM. Eventually I got to the point shown in the log attached, but for all I know I've been going down the wrong path right from the start. Please help. [kconfig_errors_fw12ec.txt](https://github.com/user-attachments/files/24547771/kconfig_errors_fw12ec.txt) All I want to do is change some hardcoded constants that define the PL1 limit of the FW12's CPU in various scenarios in [zephyr/program/framework/sunflower/src/cpu_power.c](https://github.com/FrameworkComputer/EmbeddedController/blob/fa46a9099d169ce03768f0451feb4ff0d534f0c3/zephyr/program/framework/sunflower/src/cpu_power.c).
