Kernel size above KERNEL_IMAGE_MAXSIZE

Kernel size above KERNEL_IMAGE_MAXSIZE

[Jaap de Jong]

Hi All,
not sure if I should put this here.
If I define KERNEL_IMAGE_MAXSIZE below my actual kernel size I get this 
ugly error:

ERROR: linux-at91-4.9.28-r0.4 do_sizecheck: Function failed: 
do_sizecheck (log file is located at

Either poky/meta/classes/kernel.bbclass should be changed to run 'die' 
instead of 'warn' or in poky/meta/classes/base.bbclass a function 'warn' 
should be added. Not sure which. I tend to the first option: if the 
kernel image is too large then this is an error.
