N900 u-boot breaks 3rd party application.

Hi,

When trying to install pali's u-boot I get : "u-boot with kernel 2.6.28-omap1 break the third party package policy".

I've seen this https://github.com/postmarketOS/pmbootstrap/issues/1371

But I don't understand how to do, to install u-boot safely with apt-get.

I think I've got another boot program installed because when I start with keyboard open I see several entries including "Debian", but I cannot get a "u-boot console" mentioned in the wiki.

Thank's in advance!
