The smsc911x has a bootstrap pin for detecting an external phy.
Unfortunately this is pulled into the wrong direction on the pcm037
board, so force internal phy with platform data.

The i.MX27/31 have the second chip select enabled by reset default.
This can be considered as a hardware bug, because even boards which
need this settings cannot work out of reset because of the missing
initialization sequence. Detect this reset default setting and disable
this chipselect then to be able to properly detect the SDRAM size.

omap3 has a soc specific reset function, make sure it calls common_reset
so that the proper CPU flags are set.

We allow unaligned accesses on ARMv6 onwards, make sure the CR_A
flag is cleared so that unaligned accesses do not trap.

This patch provides a global cleanup barebox Kconfig files. This includes
replacing spaces to tabs, formatting in accordance format, removing
extraneous lines and spaces. No functional changes.

The fec has multiple clock inputs:
- 50MHz clock for generating the (R)MII clock
- bus clock
The MDIO clock is derived from the bus clock, not the 50MHz clock,
so pass this into the driver so that it can correctly configure
the MDIO clock divider.
This fixes several wrong MDIO register read problems on i.MX28 boards.

This adds support for the Garz+Fricke Vincell board. This has

This adds support for initializing DDR3 RAMs on the i.MX53 type
SDRAM controller. The code automatically detects size/layout of
the connected RAM, detects the bus width and which chipselects are
populated.
While I believe this code is not 100% generic, it is far too
sophisticated to stay in a single board directory. I'm sure
other boards could make use of this aswell.

The pll setup function is exported, so it makes sense to export
the convenience wrappers for specific frequencies aswell.

Some boards do not have a DCD table since they initialize everything
in code, so allow to skip it and leave the corresponding pointers
empty.

The code initializing the SDRAM controller is not at the same
place where SDRAM is registered with barebox. To reduce the
risk of registering wrong SDRAM sizes this patch adds a
driver for the ESDCTL which reads back the configured SDRAM
size and registers the memory found with barebox.

This adds lowlevel debug functions for i.MX. As we have a great variety
of different UARTs on i.MX currently no Kconfig support for chosing the
correct one is added. Instead we expect the user to add the correct
define and issue a compiler warning if he hasn't.
