The i.MX23 v2 architecture patch series was sligthly modified to easify
the i.MX28 architecture addition later on. So, we need now an index to
query the SSP clock frequency.

Due to a wrong rounding while calculating the clock divider the requested clock
of 25 MHz resulted into a 48 MHz clock. With this patch a clock frequency
below or equal the requested one will be set.
By using 'div' and 'rate' as vars, its also easier to check against the data
sheet.

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.

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.

Adding MCI card support for S3C2440 CPUs. This is for reference only, as there
is currently no user in the barebox tree. Maybe one with access to the A9M2440
development kit can check it on his/her system.
Checked here with my own S3C2440 based system which is not in the barebox tree.

Guessing the size of an attached harddisk (access via x86 BIOS) was needed
due to the fact, barebox can't query this information from the BIOS easily.
But with the SD/MMC cards, there will be a second user of the generic disk
handling routines. And with this media it is very easy to know its size.
This patch provides a workaround to keep the guessing feature if the size of
the registered disk is 0. If it is not 0, the given value will be used instead.
Note: This is in preparation to add MCI card support, which can be handled
like a disk drive.

Using a temp. buffer for a disk sector on the stack, seems not work. Doing so
lets the system run crazy (the stack seems to be destroyd). Don't know the
correct stack handling on ARM, but (IMHO) I also can exclude any writing across
the buffer boundaries.
Using a temp. buffer via malloc() runs also on ARM.
Note: This patch was required to add MCI card support, which can be handled
like a disk drive.

In real life this output is only a "nice to have", but most of the time
its useless and confusing. So, make it a debug feature for the interested
developer.
Note: This is in preparation to add MCI card support, which mostly come with
a partition table and can be handled like a disk drive.

Makes sure that the STOP condition is transmitted before the I2C
controller is disabled.
This fixes a problem where writing to an external EEPROM was not working
because the EEPROM waits until the STOP before initiating the write
internally.
