Also use hwconfig to configure whether the board has a FEC or not.
We then can adjust the DTS to tell Linux if there is a FEC present.
syntax:
hwconfig=fec:on if hardware has a FEC
hwconfig=fec:off if hardware has no FEC

The auto-update feature (CONFIG_UPDATE_TFTP) requires that the env
variable serverip be set for the TFTP access. If DHCP is to be used
to get the serverip env variable, this doesn't work as DHCP happens
after the auto-update attempt has run. A solution is to run DHCP in
PREBOOT, but even this is too late.
To solve this, we move update_tftp() below the PREBOOT stuff.

Some people boot images with the entry point in the middle of the blob
(like Linux with the head code in discardable .init.text), and there is no
no real requirement that the entry point be right after the mkimage header
when doing XIP, so let people specify whatever they want. If they do need
an entry right after the header, then they still can do that with normal
-e behavior.

- Removed comment on NAND (not yet supported) from lowlevel_init.S

Most controllers can check if there is a card in the slot.
However, they require pins that could be not available because

725233: PLD instructions executed with PLD data forwarding
enabled can result in a processor deadlock
This deadlock can happen when NEON load instructions are used together
with cache preload instructions (PLD). The problematic conditions
can be triggered in-the-wild by NEON optimized functions from pixman
library (http://cgit.freedesktop.org/pixman), which perform dynamic
adjustment of prefetch distance.
The workaround disables PLD data forwarding by setting PLD_FWD bit
in L2 Cache Auxiliary Control Register as recommended in ARM Cortex-A8
errata list.
The deadlock can only happen on r1pX revisions of Cortex-A8 (used in
OMAP34xx/OMAP35xx). Performance impact of the workaround is practically
non-existant.
