It's confusing to set the status of a node to disabled and afterwards
it's invisible. Similarly it's confusing to be able to enable invisible
nodes.
Also print disabled nodes.

This is a port of the official PLL errata workaround from Freescale.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.
This is based on U-Boot commit:

define additional chipselect after SPI is initialized, define this one
in main SPI initialization in PCM038 SOM.

We already have the possibility to register a mci with a certain
filename to get persistent names. However, the device needed to
find the probe parameter still has the name 'mcix'. This patch
changes this by registering the mci device with the same name
as the filename.

Since the info is device specific and not driver specific, attach
the callback to the device. This makes it possible to have a info
callback for a device which does not have a driver attached.

Some MMC cards support boot partitions. These are special regions
on the MMC card intended to put a bootloader on.
This patch adds support for these partitions, they are accessible
as /dev/diskx.boot[0|1].
Additionally the partitions can be configured bootable using a
device parameter. This can be used to mark the user area or one
of the boot partitions as bootable.
Since this feature is mostly seen on eMMC cards it is made optional
to lower the size impact for boards which do not have eMMC.

This updates the i.MX esdhc divider settings to FSLs U-Boot.
Current timings work fine for SD cards, but not for eMMC.
Although the calculation is fine according to the datasheet and reading from
eMMC works, writing is broken. Atleast on i.MX53/tqma53.
With this patch the result is the same, but uses different divider values to
achieve it.
While at it, replace the udelay with a busy-loop.

This gives the SDHCI specific registers a common name and moves
them to a separate file for use by other SDHCI like drivers.
The SDHCI spec has some 16bit and 8bit registers. The i.MX accesses
these as 32bit registers. These register defines now are named after
the SDHCI registers they combine into one, for example:
SDHCI_HOST_CONTROL__POWER_CONTROL__BLOCK_GAP_CONTROL
is the 32bit version of the SDHCI registers HOST_CONTROL, POWER_CONTROL
and BLOCK_GAP_CONTROL.

If a device does not have bad blocks loop over the eraseblocks
in the driver instead of the core. This allows the mtd_dataflash
driver to erase blocks instead of pages to gain more speed during
erasing. Also the mtd_dataflash driver modifies the erase_info
struct which causes the outer loop in the core to never end.

Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154

On ARM the boarddirs are only cleaned due to the regular file
pattern search, but are not explicitly cleaned. This makes
it impossible to clean files which are not matched by a pattern
but have to be explicitly cleaned due to adding them to extra-y.
This patch changes the board-/board-y variables to += so that
we can use $(board-) to add it to common-. This way the board
directories are also cleaned.
While touching the board-y variables anyway order them
alphabetically.
