obmc-init.sh: Use u-boot env instead of password for emergency console
The password prompt doesn't work anymore. Since it relied on the
default password, remove the password prompt and just drop into
a shell if a new enable-initrd-debug-sh u-boot environment value is set.
The security implications are the same since the default
password is public and there is a need to have access to u-boot
to set the environment value.
If the environment value is not set, kernel panic the system.
Closes openbmc/openbmc#3649
Tested: Verified kernel panic if environment value was not set, and
if it was set the emergency console dropped into a shell and basic
linux commands worked:
Mounting read-write /dev/mtdblock5 filesystem failed. Please fix and run
mount /dev/mtdblock5 run/initramfs/rw -t jffs2 -o rw
or perform a factory reset with the clean-rwfs-filesystem option.
Try to manually fix.
After fixing run exit to continue this script, or reboot -f to retry, or
touch /takeover and exit to become PID 1 allowing editing of this script.
