mmc: Add 'mmc rst-function' sub-command

2014-04-02T10:02:58+00:00

Some eMMC chips may need the RST_n_FUNCTION bit set to a non-zero value
in order for warm reset of the system to work.  Details on this being
required will be part of the eMMC datasheet.  Also add using this
command to the dra7xx README.

blackfin: mmc: Correct mmc_host_is_spi and bfin_sdh.c

2014-03-28T20:55:29+00:00

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.

mmc: Split mmc struct, rework mmc initialization (v2)

2014-03-24T10:58:56+00:00

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.

mmc: Convert mmc struct's name array to a pointer

2014-03-24T09:32:10+00:00

Using an array is pointless; even more pointless (and scary) is using
sprintf to fill it without a format string.

mmc: Remove ops from struct mmc and put in mmc_ops

2014-03-24T09:32:10+00:00

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.

mmc: Add a prototype for board_mmc_init()

2014-03-05T11:23:48+00:00

Fixes the following sparse warning:

wandboard.c:137:5: warning: symbol 'board_mmc_init' was not declared. Should it be static?

cmd_mmc.c: Drop open/close mmc sub-commands

2014-02-07T16:17:49+00:00

The open and close mmc sub-commands implement a hard-coded set of values
specific to the SMDK5250 platform.  Remove these commands as what they
did can be done instead with a series of mmc dev / bootpart / bootbus
commands instead now.

cmd_mmc.c: Add bootbus mmc sub-command

2014-02-07T16:17:49+00:00

Add a bootbus sub-command to the mmc command to allow for setting
the boot_bus_width, reset_boot_bus_width and boot_mode fields of
BOOT_BUS_WIDTH (EXT_CSD[177]).
