Yes, right, that already does it. Sorry for the noise.

Why is "rootwait" removed? From my experience adding "rootwait" is

Ah that's a good point! We add these commands in Yocto, but I forgot the 
use case without Yocto. So I will add a nv/linux.bootargs.rootfs file 
with "rootwait ro fsck.repair=yes" (fsck.repair is a systemd unit).

Normally the desired behaviour is that the bootsource can be changed
persistently by setting nv.boot.default to the desired source. This
does not work when global.boot.default gets overwritten after the nvvars
have been read from the environment.

This behaviour is not changed with this patch, but I would welcome a
patch that changes this script to the desired behaviour. This could
be done by changing global.boot.default only when nv.boot.default is
empty.



This is already implemented by a test above these changes, isn't it?

snippet from init/bootsource:
  1 #!/bin/sh 

  2 

  3 if [ -n "$nv.boot.default" ]; then 

  4 exit 

  5 fi 

  6 


  7 if [ -e /dev/mmc1.0 ]; then
  ...

Normally the desired behaviour is that the bootsource can be changed
persistently by setting nv.boot.default to the desired source. This
does not work when global.boot.default gets overwritten after the nvvars
have been read from the environment.

This behaviour is not changed with this patch, but I would welcome a
patch that changes this script to the desired behaviour. This could
be done by changing global.boot.default only when nv.boot.default is
empty.

[PATCH v5] arm: boards: phytec-som-am335x: Update boot scripts

2017-06-20 Thread Daniel Schultz 
Expand the boot scripts with EMMC and add a default file source for
expansions.

Removed "rw" and "rootwait" bootargs from existing boot scripts.
Added "rootflags='data=journal'" bootarg to SD card boot script.
