This driver to get read/write support to most I2C EEPROMs,
after you configure the driver to know about each EEPROM on
your target board. Use these generic chip names, instead of
vendor-specific ones like at24c64 or 24lc02:
24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
Unless you like data loss puzzles, always be sure that any chip
you configure as a 24c32 (32 kbit) or larger is NOT really a
24c16 (16 kbit) or smaller, and vice versa. Marking the chip
as read-only won't help recover from this. Also, if your chip
has any software write-protect mechanism you may want to review the
code to make sure this driver won't turn it on by accident.

| Add more generated files to .gitignore
barebox* is not limited to the toplevel directory, so this ignores
all files starting with 'barebox' from which we have several we do
not wish to ignore. Add barebox-flash-image to the ignore list which
seemed to be the motivation for the original patch.

the mount command used to have the syntax 'mount <dev> <type> <mountpoint>'.
This was changed to the more Linux like behaviour which specifies the
type with the -t <type> option. If a newer barebox is run on a device
with an older environment the mount command no longer works. This patch
adds compatibility to the old behaviour.

edev->init is called at eth_register time unconditionally and is supposed
to initialize the ethernet hardware. Since it's called unconditionally
this could be done by the driver without having an additional hook.
Some drivers need their initialization done earlier since they also register
a mdiobus which does hardware accesses on registration time.

Several i.MX boards (all i.MX6 boards) need to do some adjustments
to phy registers. If barebox itself does not use network, networking
won't work in the kernel if the kernel does not have the fixups. Connect
the phy at probe time so that these tweaks are done during probe so that
the kernel works without phy register tweaks. Also this has the effect
that the phy device is present and introspectable without doing fake
network transfers beforehand.
