When parts of a Nand device are not readable due to excessive bit flips
we should not bail out with an error as this means we can never repair
the device by flashing a fresh image using ubiformat. Instead, treat a
failed read as a corrupt block and ignore the read failure.

A number of devices on i.MX6 list "syscon" as second compatibility
string, among them, most importantly, is "iomuxv3" pinmux driver, which
gets probed at "postcore_initcall". Probing this driver at
"core_initcall" results in "syscon" driver usurping pinmux device and
preventing "iomuxv3" driver from loading and correctly initializing
pinmux of the system (which in turn results in a lot of sadness).
Moving this driver to be initialized at "device_initcall" time resolves
the issue.

The HABv3 images for engineering mode do not work on a production device
and the images for production mode do not work on an engineering device.
When in engineering mode the ROM checks the images, but does not stop
booting when the signatures are wrong. This means a production image
can still be booted on an engineering device. This device can be
temporarily put into production mode by writing to the HAB_TYPE shadow
fuse register. After a reset the device will come up in production mode
and the image can be tested for validity. This means that if we have to
decide between production mode images and engineering images, the
production images are a better decision. Change this accordingly.

This adds a function to enable/disable permanent write for the IIM
module so that C users no longer have to fiddle with device parameters.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Accessing the IIM registers is cumbersome. The fuses are documented with
different register strides and there is no header file available, so the
different fields have to be read in the datasheets and translated into
the barebox format over and over again. This patch adds a header file
which has defines for the various fuses (for i.MX25 only so far, but
others can be added later) along with C functions to read/write the
fields.

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

First of all the reset values of MMC interfaces are differently between
Quad and DualLite/Solo SoM.
Register VEND_SPEC2(0xC8)
Quad: 0x0
DualLite: 0x00000006
default: 0x00000006 (from i.MX6 Reference Manual)
Furthermore the ROM Code of Quad and DualLite uses the MMC interfaces
differently when it loads the bootloader from that device:
Register DLL_CTRL(0x60) Bit 25 FBCLK_SEL (0x48)
Quad: 0x0 0
DualLite: 0x01000021 1
Since the linux kernel and barebox driver doesn't reset all registers,
the MMC interface is in an inconsistent state, which leads to boot
failures for some eMMC devices on the i.MX6 DualLite SoM. The errors
look like:
mmcblk3: error -110 sending stop command, original cmd response 0x900, card status 0x400900
mmcblk3: error -84 transferring data, sector 24578, nr 2, cmd response 0x900, card status 0x0
mmcblk3: retrying using single block read
mmcblk3: error -84 transferring data, sector 24578, nr 2, cmd response 0x900, card status 0x0
blk_update_request: I/O error, dev mmcblk3, sector 24578
It's sufficient to reset register DLL_CTRL and bit FBCLK_SEL. Register
VEND_SPEC2 has no effect.
