Dear Maintainer,
Using u-boot 21.10 (which does not have support for KASLR), the generated
extlinux.conf makes the system unbootable.
This is most likely a bug in u-boot, causing it to ignore any unknown command
*and all the following ones*:
Retrieving file: /extlinux/extlinux.conf
843 bytes read in 17 ms (47.9 KiB/s)
Ignoring unknown command: kaslrseed
Ignoring unknown command: append
Ignoring unknown command: kaslrseed
Ignoring unknown command: append
Attached is a patch working around this issue in u-boot-menu.
Thanks,
Arnaud

Subject: [PATCH] u-boot-update: put `kaslrseed` last
When using a version of u-boot without KASLR support (21.10 in this
case), having this command set makes all following lines to be ignored,
even though they contain valid commands:
Retrieving file: /extlinux/extlinux.conf
843 bytes read in 17 ms (47.9 KiB/s)
Ignoring unknown command: kaslrseed
Ignoring unknown command: append
Ignoring unknown command: kaslrseed
Ignoring unknown command: append
Ensuring `kaslrseed` is the last command is enough this work around this
`u-boot` bug.
