Subject: [PATCH 1/1]
Could you please omit the "1/1" part is this is a single patch that does not belong to some series?
[On the other hand, I kind of feel that this *is* actually part of your qemu series ?]
Best regards,
Wolfgang Denk

Comments are difficult to distinguish from real commands here. It might be readable if we use another comment style, or another command prompt.
And again, thanks for your continued work to improve qemu "getting started" guide.

Wouldn't it make sense to use something like
(CFG_FLASH_BASE + CFG_MONITOR_LEN)
instead?
