We used to eth_open/eth_halt the network devices during NetLoopInit
which is called whenever the user enters a network command.
Change this behaviour so that the current network device gets opened
when making it the current one.
With this change it's always possible to send packages and we are able
to implement a new network stack in the next step.

theses commands allow low level access to i2c bus and can be useful
to setup an i2c device without having to add code, compile and flash
barebox.

_start is now exception_vectors since it was rewritten in C

The kernel for the imx35 pdk doesn't do any detection for board and chip revision. This patch passes the info to the kernel so that v2 boards/chips boot properly.
imx35pdk: make COMPARE pad a GPIO1_5 output
This pad is an interrupt source, active low for one of the external ICs.
fix up/remove unnecessary white space.

Lets translate the startup code to a language we all understand better.
Tested on pcm038 (arm v5) and pcm043 (arm v6).

Instead of having seperate cache flush functions in the startup code
we want to call the generic functions. To accomplish this they have
to be in the bare_init section.

As a side effect don't build barebox.S when barebox.bin is updated. I
didn't manage to keep the old behaviour and I consider it cleaner this
way.

Copy the behaviour from Linux which does:
cfi_send_gen_cmd(0xAA, cfi->addr_unlock1, chip->start, map, cfi, cfi->device_type, NULL);
...
(Notice the third parameter which is simply chip->start).
