This board wasn't changed properly, as it was merged in the short
timeframe where the signature change waited to be applied. Change
it now to get rid of the compiler warning.

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.

For small systems we would put the zImage at 8MiB after
the start of memory, and put the DT a bit after the zImage.
When we encounter an image which is bigger than 8MiB
uncompressed, the kernel would try to relocate itself
and overwrite the DT.

triggering the kernel relocation.

If we have two discontinuous memory banks we want to move
the malloc area into the upper bank by default to leave as
much free space in the lower bank, where we have to place
kernel, oftree and initrd.

Not needed anymore, as barebox now accepts FDTs outside
of it's visible DRAM, as long as it's a valid pointer.

Mostly to make it clear that boarddata needs to be
something we can dereference.
As this is a pretty invasive change, use the opportunity
to make the signature 64bit safe.

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
12:34:56:78:9A:BC

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.

If there's packet loss and the remote server needs to retransmit,
there is falsely no timeframe left because TIMEOUT (server wait time)
and TFTP_TIMEOUT (abort timer) are the same.
This patch increases TFTP_TIMEOUT.
