clk: mxs: Use device tree provided clock lookups ...

When probing from the device tree use the device tree provided clock
lookups. So far we only used the clock lookups based on the physical
base address of the device, but these should go sooner or later.

arm: mxs: Add Kconfig option for device tree boards ...

ARM: mxs: Allow to compile all boards for a SoC together ...

All boards in mach-mxs support multi image, so we no longer have to make
the board type a choice. Let the user compile all boards for a SoC
together. We cannot compile i.MX23 together with i.MX28 though, there
are still many conflicting defines which use the IMX_ namespace which
are really SoC specific.

Set model and hostname at boardlevel ...

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.

Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

ARM: MXS: introduce stmp device support ...

MXS specific devices have some common infrastructure in the kernel
known as STMP devices. We have the same in barebox, but with a
mxs_ prefix instead of a stmp_ prefix. As some STMP devices are
also found on i.MX6 move the common infrastructure out of MXS
specific files and use the stmp_ prefix.

This is done in preparation for i.MX6 NAND support.

there is an expansion board plugged in and what expansion board it is.

arm: mxs: add write support for ocotp ...

Since we now can change HCLK and VDDIO, we can now support writing to

need to fill a temporary buffer when offset or count is not aligned. The
write is also protected by a special device variable.
