The issue isn't a specific commit.

The issue is the kernel is too big.

The bootloader of this device only reads 0x29F000 bytes in hex or

2748416 bytes, around 2.6Mb in decimal.


In the Github PR (1) they see they can only work around this by

making an u-boot bootloader that can be loaded instead of the kernel.

Then this u-boot will load the kernel with no limitations.
