6fe9febb8a [MMC] Always use a sector size of 512 bytes
Both MMC and SD specifications specify (although a bit unclearly in
the MMC case) that a sector size of 512 bytes must always be
supported by the card.

Cards can report larger "native" size than this, and cards >= 2 GB
even must do so. Most other readers use 512 bytes even for these
cards. We should do the same to be compatible.

148f93d59c [ARM] 3751/1: i.MX/MX1 SD/MMC use 512 bytes request for SCR read
Patch from Pavel Pisa

This is another approach to SDHC deficiency workaround.
It seems, that previous solution based on 16 bytes (FIFO length size)
read is still timing sensitive on genirq and fully preemptive kernels.
The new solution is backuped by M9328 UM statement, that only 512 byte
block are working properly and by 2.4.26 FreeScale's SDHC code.

Jay Monkman reports significant improvement on code based
on this driver after applying this change on MX21 as well.

c723e08af1 [ARM] 3744/1: MMC: mmcqd gets stuck when block queue is plugged
Patch from Juha [êölä

When the block queue is plugged, mq->req must be set to NULL.
Otherwise mq->req might be left non-NULL, even though mmcqd is
not processing a request, thus preventing the MMC queue thread from
being woken up when new requests do arrive.

bab7696184 [MMC] sdhci: Avoid sdhci DMA boundaries
The sdhci controllers will issue an interrupt when a configurable number of
bytes have been transfered using DMA. The purpose is to handle multiple,
scattered memory pages.

Unfortunately, it requires that all transfers are completely aligned to
memory pages, which we cannot guarantee. So we just disable the function.

1. Replace calls to DBG() with pr_debug().
2. 'host' can never be null, so don't bother checking for that case.
3. Remove SA_SAMPLE_RANDOM from request_irq().  [Patch from Matt
Mackall]
4. clk_get() doesn't return NULL on error - need to test returned value
with IS_ERR().
5. Free resources if clk_get() or request_irq() fails.

a3fd4a1b9c [MMC] Convert all hosts except mmci to use data->blksz
The MMC specification allows non-power of two block sizes.  As such,
we should not pass the log2 block size to host drivers, but instead
pass the byte size.

However, ARM MMCI can only work with log2 block size, so continue to
pass both the log2 block size and byte block size.  This means that
for the moment, the byte block size must remain a power of two, but
this is the first stage of removing this restriction for other hosts.
