How to chain u-boot with something that I don't understand.

[Mario Marietto]

 You are right :

this image has kernel 6.1.11 and it's not good because kvm has been
disabled for arm 32 on kernel 5.7

230220-01 - debian bookworm image for the snow chromebook - samsung
xe303c12
<https://github.com/hexdump0815/imagebuilder/releases/tag/230220-01>

   - see:
   https://github.com/hexdump0815/imagebuilder/tree/main/systems/chromebook_snow
   - kernel version used: v6.1.11 lts


And this image is also not good,because it uses a lower kernel than 5.4 :

220619-01 - debian bullseye and ubuntu jammy images for the snow chromebook
- samsung xe303c12
<https://github.com/hexdump0815/imagebuilder/releases/tag/220619-01>

   - see:
   https://github.com/hexdump0815/imagebuilder/tree/main/systems/chromebook_snow
   - kernel version used: v5.18.1
   - multi generation lru extra kernel patches integrated for better
   performance under memory pressure
   - some initial spring support is there, but there is still a lot of work
   required to make it really work


In any case,no problem,because I've already been able to recompile kernel
5.4.244 and I have enabled all the kvm flags succesfully. So,what I will do
when one of those images will boot,will be to recompile kernel 5.4.244.

Now,let's jump to the main question : can I chain u-boot with syslinux ?
