This EEPROM is found on the expansion boards available for the 10036
module. Since we won't need to do anything fancy except reading/writing
from it, use bitbanging to communicate with it.
This EEPROM will hold mostly the board_id so that we can determine if
there is an expansion board plugged in and what expansion board it is.

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.

When the i.MX28 boots from USB, the ROM code sets this bit. When
after a reset the ROM code detects that this bit is set it will
boot from USB again. This means that if we boot once from USB the
chip will continue to boot from USB until the next power cycle.
To prevent this (and boot from the configured bootsource instead)
clear this bit here. This bit is not documented in the datasheets,
it was figured out the hard way. Whether this is the same on i.MX23
is currently not known.

If a second bootstream was used, there was a sanity check which was not
only wrong (using erasesize instead of writesize) but also superfluous
(we got the block from an existing cdev, so it must be in the flash
range). Simply remove it to make bcb work as expected.

Since commit 2f6b1f7690640f571f8e72fc2f2564acb2e13778 the pull-up and
bitkeeper handling for i.MX23/28 is correct. But now it is important to
distinguish these pin features as their programmed bit values are different.
With this patch the bitkeeper and pull-up enable/disable bits are now handled
separately.

While a set bit enables the pullup (if exists) it disables the bitkeeper (if
exists). Both features are using the same register bit and only one of this
feature is present on a per pin base.

We write a proper FCB, but no DBBT since it is unresolved how to keep it
in sync with Linux-based BBTs. Also, we imply searchcount = 4 and stride
= 64 (which is the default) until we can verify via ocotp.

Currently the watchdog is occupied for system reset. This usage collides with
the dedicated usage of a watchdog. This patch change the behaviour of at least
i.MX23/i.MX28 where the chipset supports a simple and powerful alternative

Since we now can change HCLK and VDDIO, we can now support writing to
OCOTP. Writing is done via a special data register. This is u32, so we
need to fill a temporary buffer when offset or count is not aligned. The
write is also protected by a special device variable.
