Hi Paul,
please consider merging the following two patches.
They are both pre-requisites for
"mmc, ARM: Add zboot from eSD support for SuperH Mobile ARM"
which I plan to submit to Russell King.
These patches were originally submitted in a for patch series
however they do not depend on any of the other patches in the series
so I am posting them independently.
These patches apply against Linus's current tree
and I am not aware of any particular prerequisites for them
other than that the 2nd patch depends on the 1st one.

These headers and helpers will also be used for SDHI boot
so the mmcif name will start to make a lot less sense.

This is my second attempt to make this enum generally available.
The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h.
However this is not sufficiently generic as the enum will be
used by SDHI boot code.

Hi,
this patch fixes problem with some SD cards during initialization. Not all SD(HC) card can run at even 375kHz. Sets
minimal frequency to 200kHz.
And in function "at91_mci_set_ios" is limit to maximum division, it's only 8 bit value.

What does this have to do with
"[PATCH 1/2] mmc, ARM: Rename SuperH Mobile ARM zboot helpers" ?
which is the message which you hit your mailer's "reply" button on?
Please don't pollute email threads.

Sorry, it's not as trivial as I thought. For some reason your mailer is
introducing additional message IDs in the 'References' header which are
causing the message to be incorrectly threaded. Here are the original
two messages:
From: Simon Horman <horms@verge.net.au>
Subject: [PATCH 0/2] mmc: zboot helpers
Message-Id: <1300949648-15078-1-git-send-email-horms@verge.net.au>

Message-Id: <1300949648-15078-2-git-send-email-horms@verge.net.au>
And your messages:

both of which reference Simon's unrelated emails. No idea how you're
doing that, but both of your messages seem to be completely unrelated
to Simon's two.

Please repost as a new email with a proper change log. This patch
shouldn't depend on the CDU audio driver patch. This should still build
and run, just without audio support.
Few more comments below.

You have max_speed_hz set as (1 * 1000 * 1000) in some cases and 1000000
in others. Please be consistent. Nitpicky: chip_select and bus_num
should go next to each since they are related.
