Current message indicating that SD card isn't
mounted is misleading if the card has only one
partition.
Updated the message to indicate that mounting
the specific partition failed.

Some variants of the i.MX53 do not allow to run at 1GHz, so
pass a cpu frequency parameter to the lowlevel init function.

Whether the controller works in 8bit mode is not only dependent
on the controller but also on the board having wired up 8 data
lines, so put a capabilities field in platform data.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Currently we test the cards capabilities for being 8bit capable.
This does not work since noone ever sets this bit. Unfortunately
there is no bit to test 8bit capability, so we introduce a patch
from the kernel which puts the mmc card into 8bit mode and tests
whether it can succesfully read the ext_csd in this mode.

Too often I have waited to get a reaction from this driver
when something goes wrong. Use timeout loops instead of
inifinite polling loops.

This is quite useful when multiple SD cards are present so spare
some bytes to print this information.

There will always be the next integer number unless we register
INT_MAX disk devices which is rarely the case.

The mci layer uses pr_debug throughout. Use dev_dbg instead
which is very useful when multiple cards are involved.

The mci layer currently passes around a struct device_d for
its internal use. Apart from being confusing this drops
typesafety for no good reason. Instead, pass around a struct
mci.

The s3c driver passes around a struct device_d * internally in which
it is never interested in. Instead pass around a struct s3c_mci_host
and get rid of all this ugly void * derefs.

Yes, it does make sense. First there will always be the next
hardware which has multiple controllers. Also, we shouldn't
give bad examples to others.

As we'll need more arguments to set_ios over time put them
in a struct mci_ios like the kernel does.

Whether a card is high capacity is checked in
sd_send_op_cond/mmc_send_op_cond. Remove the wrong check in
mmc_change_freq which wrongly recognizes some eMMC flash
as high capacity.

Remove what is an apparently valueless Kconfig variable HAS_OMAP_NAND.
A search of the entire source tree shows:
$ grep -r HAS_OMAP_NAND *
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig: select HAS_OMAP_NAND
arch/arm/mach-omap/Kconfig:config HAS_OMAP_NAND
arch/arm/configs/phycard_a_l1_defconfig:CONFIG_HAS_OMAP_NAND=y
$
where the definition of that variable is simply:
config HAS_OMAP_NAND
bool
so it seems pretty clear it can be removed as nothing is using it.

Without the proper OMAP3 or OMAP4 dependency directives, you get the

When unaligned writes are used, typically doing a cp file /dev/mtdraw0.foo,
the alignement correction code was incorrectly handling such cases, and
didn't return the expected number of written bytes.
This was tested on a 528 block size.

At least ARM allows us to dump the stack, but we currently
have no prototype for this. Add a dump_stack prototype and
provide a static inline function for architectures without
stack dump support. Also, call dump_stack() in panic() to
provide more information in the case of a panic.

Now that we don't need malloc for the console anymore it's
safe to call printf anytime, so switch the initcall debugging
to regular debug() statements..
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Currently we just hang when an initcall fails. This resulted
in most initcalls just returning 0 unconditionally. Instead
of hanging which usually leaves the user without a clue what
happened just continue and hope for the best.
