The i.MX7 has two pinmux controllers, the regular and the LPSR
controller. The LPSR pinmux controller doesn't have any sel_input
registers, instead they can be found in the regular pinmux controller.
This means whenever we want to apply the the sel_input setting for
the LPSR controller, we have to apply them to the regular controller
instead.
In barebox take the easy way out and just add the difference of the
two base addresses to the register offset. The same issue is present
in the Kernel aswell, but when the bootloader already configured
the pins correctly nobody notices when the Kernel sel_input setup
effectively is a no-op.

The i.MX6 series SoC type is determined by barebox by examining the
USB_ANALOG_DIGPROG aka IMX6_ANATOP_SI_REV register. This register is located
at a common offset for all mx6 SoC - except for i.MX6SL where a different
offset is used. This creates a dilemma while distinguishing the mx6sl from
non-mx6sl SOC since the SoC type identification register location is type
specific itself.
Access to undocumented and probably invalid or unpredictable registers should
be avoided as possible. For the mx6sl detection an access to the general
USB_ANALOG_DIGPROG @0x260 cannot be avoided when running on mx6sl. This
register contained the value 0x00014009 for different mx6sl Rev. 1.2 based
e-book readers using MCIMX6L7DVN10AB and MCIMX6L8DVN10AB SoC. This
implementation assumes the value of MAJOR_UPPER (here 0x01) to be smaller
than the smallest non-6sl MAJOR_UPPER (0x61 for mx6s).

The NoC regulator only passes the QoS signals through if it is

over other requests. The kernel may change it to some other setting

Some i.MX53 want to setup the SDRAM from C code rather than
from DCD tables. The image size for these boards is limited
to the internal SRAM size. To overcome this limitation for
i.MX53 boards booting from NAND implement an xload mechanism
to load only the PBL to SRAM and let barebox load the rest
of the image itself after SDRAM has been initialized.

The i.MX31 SPI interface was refered by freescale as spi_ver_0_4 in one
of their older vendor extended linux releases. spi_ver_0_4 differs only
in minor aspects to spi_ver_0_7 (i.MX35) which is already supported by
barebox.
Regarding barebox, the differences boil down to the location and length
of the CHIP SELECT and BIT COUNT/BURST LENGTH elements of CONREG. The
spi_ver_0_4 variant is limited to single word bursts with a maximum of
32 bits_per_word.
Add support for the i.MX31 SPI interface to the barebox spi_ver_0_7
implementation.

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.

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.
