Issue:
Encountering a error during kernel uncompression on the Raspberry Pi 4 when utilizing the Scarthgap Yocto Release and meta-raspberrypi layer on the master branch. This issue manifests specifically with kernel version 6.6 on the raspberrypi4 machine. Upon booting, following the u-boot initialization, the kernel uncompression process triggers an error, causing the board to enter a reboot loop.

Observations:
Curiously, this issue does not persist when utilizing the raspberrypi4-64 variant. In this case, the kernel operates without encountering any issues.
Steps to Reproduce:
Utilize the Scarthgap Yocto Release on a Raspberry Pi 4.
Ensure the kernel version is 6.6.
Observe the boot process, noting the error during kernel uncompression.
Expected Behavior:
The kernel should uncompress successfully on the Raspberry Pi 4 using the Scarthgap Yocto Release, allowing the board to boot normally without encountering errors.
Additional Information:
This issue is specific to the raspberrypi4 machine and kernel version 6.6.
No similar issues have been observed with the raspberrypi4-64 variant.
When using the kernel 6.1 the problem does not occur.
Any insights or resolutions would be greatly appreciated.
