Patches for -next

[Sascha Hauer]

Hi All,

Here are several patches leading to i.MX51 babbage support in the end.
Not all patches are directly i.MX51/babbage related but are needed
to make it work.

[PATCH 02/17] mci: Add i.MX esdhc support

[Sascha Hauer]

This adds a driver for the esdhc controller found on Freescale
i.MX25/35/51 SoCs.

This code is based on the U-Boot driver.

[PATCH 11/17] mci: handle SD cards < 2.0 correctly

[Sascha Hauer]

With SD cards older than 2.0 the sd_send_if_cond() fails. Do
not assume it's an MMC card in this case. Instead, assume
it's a MMC card if sd_send_op_cond() fails.

[PATCH 12/17] mci: align write buffer if necessary

[Sascha Hauer]

Most SD controllers need some kind of alignment for writing
blocks. Instead of coding this in every driver, align write
blocks to a 4 byte alignment in the mci layer. For DMA
accesses we may need bigger alignment, but let's solve this
problem when we have it.

Are you sure you want/need additional partitions on a disk without a 
persistant partition table?

@Marek: You need this patch to make your SD card work on the mini2440.

No ;)

It is not completely clear to me how we handle this best. On i.MX51 I
have some problems with the partition table. When booting from SD card
we just dump barebox.bin to the raw card. The partition table is then
part of barebox.bin. Unfortunately we do not know (or at least we don't
want to specifiy) the size of the card during compile time.

How should a bootable SD card should be partitioned anyway? We could add
partitions for barebox/env/kernel/root like usual, but this does not
look very standard for SD cards (and we even need extended partitions
if we want to add a data partition). We could also add just a single
partition for root and maintain the rest outside of any partition.

I haven't really thought this to an end.

Sascha

If you want your kernel to work with this card you will need a partition 
table. Its more like a hard disk, not like a flash memory of NAND or NOR 
type. So, IMHO you will need a full blown partition table when you want use 
the SD card outside barebox.

Your card is already probed and now the disk layer tries to read the partition 
table.

There seems a bug in one of the routines. The cards states:

> Transfer speed: 25000000

but the mci-core wants more:

> IO settings: bus width=1, frequency=50625000 Hz
                                      ^^^^^^^^^^^
I will check for it.

Yes I know. Do we need a fdisk command for barebox?

IMHO not for barebox. Because to setup a full system on an SD card you would 
also need tools to create a filesystem on these partitions. That's not the 
job of a bootloader. We just have to handle partition tables in a correct 
manner.

I think we can support fdisk but we do not need to create fs we can just dump
it from tftp & co

and the env can be see as a fs
