bit is set.

0b2da7e209 blackfin: mmc: Correct mmc_host_is_spi and bfin_sdh.c
In the recent mmc cleanup, the mmc_host_is_spi macro was broken and
bfin_sdh.c had mmc->bus_width turned into mmc_bus_width(mmc), both of
which were incorrect.

93bfd61677 mmc: Split mmc struct, rework mmc initialization (v2)
The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.

On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.

Typically the initialization got something like this in every driver.

	struct mmc *mmc = malloc(sizeof(struct mmc));
	memset(mmc, 0, sizeof(struct mmc);
	/* fill in fields of mmc struct */
	/* store private data pointer */
	mmc_register(mmc);

By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:

	struct mmc = mmc_create(&cfg, priv);

All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.

Changes since v1:

* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.

22cb7d334e mmc: Convert mmc struct's name array to a pointer
Using an array is pointless; even more pointless (and scary) is using
sprintf to fill it without a format string.

ab769f227f mmc: Remove ops from struct mmc and put in mmc_ops
Remove the in-structure ops and put them in mmc_ops with
a constant pointer to it.

This makes the mmc structure smaller as well as conserving
code space (in theory).

All in-tree drivers are converted as well; this is done in a
single patch in order to not break git bisect.

Changes since V1:
Fix compilation b0rked issue on omap platforms where OMAP_GPIO was
not set.

130fbeb1c5 blackfin: Add <asm/clock.h> to numerous drivers
With d6a320d we moved some clock externs out of blackfin_local.h and
into clock.h but now need to include <asm/clock.h> in more drivers to
avoid warnings.

76b40ab41e Merge u-boot/master into u-boot-ti/master
In master we had already taken a patch to fix the davinci GPIO code for
CONFIG_SOC_DM646X and in u-boot-ti we have additional patches to support
DA830 (which is CONFIG_SOC_DA8XX && !CONFIG_SOC_DA850).  Resolve these
conflicts manually and comment the #else/#endif lines for clarity.

Conflicts:
	arch/arm/include/asm/arch-davinci/gpio.h
	drivers/gpio/da8xx_gpio.c

No other driver sets up the part type to DOS in their init, and it
doesn't seem to be needed as `mmcinfo` and `mmc part` stll work, so
drop it.

48972d907a mmc: Implement card detection.
Check for card detect each time an MMC/SD device is initialized. If card
detection is not implemented, this code behaves as before and continues
assuming a card is present. If no card is detected, has_init is reset
for the MMC/SD device (to force initialization next time) and an error
is returned.

8feafcc49c MMC: make b_max unconditional
Make existing field b_max field in struct mmc unconditional
and use it instead of CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_bread
and mmc_bwrite.

Initialize b_max to CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_register
if it has not been initialized by the hw driver.

Initialize b_max to 0 in all callers to mmc_register.
