In barebox network packets always go out at the current ethernet
device and are expected to be received from the current interface.
This has some side effects. When for example an NFS is mounted when
one interface is active and the interface is changed afterwards the
NFS packets leave the new interface, but the NFS server won't be
reachable there.
Instead of changing the whole network traffic to the current ethernet
interface we now initialize a network connection with the current
network interface, but then the connection will continue to use that
interface even when the current interface is changed.

When doing an ifup set the current interface to the one just
brought up so that it is actually used.

With CONFIG_PARTITION_NEED_MTD enabled we use mtd rather than devfs
directly to create partitions on mtd devices. Since:

The bad block aware device creation doesn't work if this option
is disabled. With this we remove CONFIG_PARTITION_NEED_MTD and always
use mtd partitions on mtd devices.

When iterating over directories in order to find boot scripts do
this alphabetically to get a predictable order. This can be done
with glob() rather than readdir().

When there are multiple bootsources barebox should try booting them
until one succeeds. This is broken because we bail out of the iteration
loop with a goto. Remove the goto to fix this.

Some of the barebox specific changes that were added in commit
e0316b4dd7 got lost during the switch to use
upstream dtsi files in commit bb7cf71cff.
Especially the memory size is important since we have two different memory
sizes which have to be handled.

Subject: [PATCH] Fix the options and protocols used by the loadx command.
It seems like the loadx command was improperly copy/pasted from the loady
implementation, and was trying to load files using the ymodem protocol. This
patch should fix the command so that it uses xmodem, implements the -t option
and outputs the correct baudrate being used.

This isn't much different from the default 1,16V

It's not safe to ramp up the CPU clock speed to
1,4 GHz on all T30 SKUs, as this may result in failure
to start the kernel properly. Start CPU at 600 MHz,
which is safe even for the slowest SKUs.

For small systems we would put the zImage at 32KiB after
the start of memory, and put the DT a bit after the uImage.
The kernel will always try to relocate itself and overwrite
the DT.
Try to be more clever at uImage placement to avoid
triggering the kernel relocation.

FUSEs (OTP registers) can be written via /dev/imx-ocotp character device.
For example, writing MAC 12:34:56:78:9A:BC can be performed as
> mw -l -d /dev/imx-ocotp 0x8c 0x00001234
> mw -l -d /dev/imx-ocotp 0x88 0x56789ABC
and reading as
> md -l -s /dev/imx-ocotp 0x88+8
00000088: 56789ABC 00001234
, where 0x88 (0x22*4) and 0x8C (0x23*4) are offsets of MAC OTP registers.
Notice: FUSEs are PROM, so "0" (unprogrammed) bits
can be replaced with "1" (but not vice versa) only once.
Also, for MAC there are convinient parameters:
> ocotp0.permanent_write_enable=1
> ocotp0.mac_addr=12:34:56:78:9A:BC
imx_ocotp 21bc000.ocotp: reloading shadow registers...
imx_ocotp 21bc000.ocotp: reloading shadow registers...
> echo $ocotp0.mac_addr

RX DMA Head Descriptor Pointer can get 0 when there is a lot of traffic,
which results in a timeout error. A good way to provoke this error is by
sending lots of ARP requests. This patch makes sure that the RX DMA Head
Descriptor Pointer is set.
The origin driver, from which this is derived, already contains this fix.

there is falsely no timeframe left because TIMEOUT (server wait time)
