[Arm-netbook] u-boot and extlinux.conf directives

[Nick Hardiman]

Will the u-boot on the computer card be happy with these syslinux config directives?

My u-boot skipped some of these with messages like:
Ignoring unknown command: ui
Ignoring unknown command: totaltimeout

This is probably my fault - I was thrashing around in the dark. But I thought I’d check.

Thanks, Nick

i have no idea - as in, you're the first person i've heard of who has
used the combination of u-boot and sysconfig. most people in the
embedded world use u-boot to specify one and only one linux kernel,
using u-boot parameters to do it, editing uEnv.txt (if the version of
u-boot supports that) or boot.cmd (if the version of u-boot supports
that and its conversion to boot.scr).

if there's a version of u-boot that supports syslinux you'd need to
track it down and follow the documentation on that. i've just tried
using mainline u-boot and it works fine so chances are you'll be ok.
