T1042RDB is a Freescale reference board that hosts the T1042 SoC
(and variants). The board is similar to T1040RDB, T1042 is a reduced
personality of T1040 SoC without Integrated 8-port Gigabit(L2 Switch).

T1042RDB is configured with serdes protocol 0x86 which can support
following interfaces
- 2 RGMII's on DTSEC4, DTSEC5
- 1 SGMII on DTSEC3
DTSEC1, DTSEC2 are not connected on board.

This Patch
- add T1042RDB support
- updates README file for T1042RDB details and update commands for switching
  to alternate banks from vBank0 to vBank4 and vice versa

This patch also does minor clean ups for fdt defines for T1042RDB and
T1042RDB_PI board

Since dev->req_seq value is initialized from "reg" property of fdt node,
there is posibility, that address value contained in fdt is greater than
INT_MAX, and then value in dev->req_seq is negative which led to probe()
fail.

This patch fix this problem by ensuring that req_seq is positive, unless
it's one of errno codes.

At the high level, the problem is that we set gd multiple times (and
still do, even after the commit we're reverting).  We set important
parts of gd to the copy which is not above stack but rather in the data
section.  For the release, we're going to revert this change and for the
next release we shall correct things to only, really, set gd once to an
appropriate location and ensure that comments about it are correct too.

When a DNS query is sent out, the ethernet packet can get directed to
the MAC address of a server that was communicated to before.  This is
wrong when the previously stored MAC address corresponds to a different
server's IP address, i.e. when the IP address of the previous and the
current communication are different.

The error can get reproduced by running a sequence of e.g. a TFTP
download and a DNS query, where the TFTP and DNS servers reside on
individual machines.

The fix is to clear the server's MAC address that might be left from a
previous operation, and to fetch the peer's MAC address in a new ARP
lookup, before the DNS query is sent.  This is the approach taken in
other network services, like 8e52533d ("net: tftpsrv: Get correct
client MAC address").

For the SPL configuration, "make <dir>/<target>" is used.
Here,
  <dir> is either "spl" or "tpl"
  <target> is one of "config", "menuconfig", "xconfig", etc.

This commit adds two checks:

[1] If <dir> is given an unsupported subimage, the configuration
    should error out like this:

  $ make qpl/menuconfig
  ***
  *** "make qpl/menuconfig" is not supported.
  ***

[2] Make sure that "CONFIG_SPL" is enabled in the ".config" before
    running "make spl/menuconfig.  Otherwise, the SPL image
    is not built at all.  Having "spl/.config" makes no sense.
    In such a case, the configuration should exit with a message:

  $ make spl/menuconfig
  ***
  *** Create ".config" with "CONFIG_SPL" enabled
  *** before "make spl/menuconfig".

This driver was upstreamed without an SMSC copyright, even thought it seems
that SMSC was the original author.

See the kernel version for a code comparison:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2f7ca802bdae2ca41022618391c70c2876d92190

It's not clear who actually moved this code, or whether the kernel was the
original source, or somewhere else, but it probably should still have the
SMSC copyright.
