[U-Boot] [PATCH 1/1] qemu_mips: update doc to generate and to use qemu flash, ide file

Dear Jean-Christophe PLAGNIOL-VILLARD,

In message <1220905638-9768-1-git-send-email-plagnioj@jcrosoft.com> you wrote:

> 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

Hmm, the patch above can't be applied to the current git.  Could you
confirm it?

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

you get a chance to update this doc in the future, please correct them.

Wouldn't it make sense to use something like

	(CFG_FLASH_BASE + CFG_MONITOR_LEN)

instead?

Now we have CONFIG_SYS_* instead of CFG_* in this area.  Could you
update and re-send the patch, please?
