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.

Provide minimal regulator support. Only supported operations are enabling
and disabling regulators. Association of devices with their regulators is
limited to devicetree only. If regulator support is disabled the API expands
to static inline stubs so consumers can still use the API.

when $target is a path relative to $objtree the script fails.
This is because we cd to $basedir and then copy to $tempdir which
then is no longer valid. Fix this by converting $tempdir to an
absolute path first.
