Help on getting serial output on the arndale board
Hi,
Now that the Arndale board is supported in upstream Xen I don''t get any

with no luck:
The xen repository I''m using is:
git://xenbits.xen.org/xen.git

Arndale: domU not booting
...dtb_addr_r
/exynos5250-arndale.dtb''//
//setenv bootcmd_load_script_mmc ''ext2load mmc 0:1 $script_addr_r

//setenv bootcmd ''run bootcmd_load_script_mmc; source $script_addr_r''//

//setenv dom0_bootargs ''console=hvc0 ignore_loglevel psci=enable

Save the changes with saveenv and simply boot.
At this point, I was able to launch the kernel and Xen successful...
