Description

Booting the current pre-assembled generic kernel-image of trunk via DHCP/TFTP on a Mikrotik 493GAH causes a kernel panic as the 'root'-kernel-parameter is missing.

Current kernel parameter (copied from console-log):

console=ttyS0,115200 gpio=4023 HZ=340000000 mem=256M kmac=<obfuscated> board=493G boot=1 mlc=2 rootfstype=squashfs,jffs2 noinitrd

Log on serial console:

[    8.730000] VFS: Cannot open root device "(null)" or unknown-block(0,0)
[    8.740000] Please append a correct "root=" boot option; here are the available partitions:
[    8.740000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

The images built from the 'generic' subtarget will not work on the RouterBoards. We have a separate 'nand' subtarget for that.
