Hello,

While I am testing on your new patch series on the Arndale Board, I
have found some mismatching items between wiki and source code.

1. dts path problem:
 from kernel 3.9 ( my guessing.. :) ), dtb file will be created in the
same directory with dts file: arch/arm/boot/dts/*.dtb.
 However, in the wiki, it still describe dtb path is in arch/arm/boot/*.dtb.

2. early_printk uart:
 In the branch name "arndale" from your linux tree
(git://xenbits.xen.org/people/julieng/linux-arm.git),
exynos5250-arndale.dts describes "console=com1,dbgp com1=serial0" as a
boot argument for early_printk.
 However, in your newer patch series for XenARM,
${xensrc}/drivers/char/arm-uart.c try to find console that has node
name as "dtuart". So, I think it is required to modify
"exynos5250-arndale.dts" file like:
 - console=com1,dbgp com1=serial0
 +console=dtuart dtuart=serial0

Please consider this matters.

I am really enjoying to testing with your newly release patch series
on the arndale board.
But, I am still facing some problems :( I will post the problem to the
mailing list later.

Sincerely yours,
