ratp: use xstrndup() instead of a custom xmemdup_add_zero() ...

The console operations done via RATP expect strings, so just use
xstrndup() instead of defining a custom method.

ratp: allow building without full console support ...

Make CONFIG_RATP a selectable config option, so that the user can
enable RATP support without explicitly needing to enable the full
console support over RATP (e.g. only for RATP FS or built-in command
support).

The full console can still be explicitly enabled with
CONFIG_CONSOLE_RATP.

ratp: implement generic command support ...

The RATP implementation now allows executing generic commands with a
binary interface: binary requests are received and binary responses
are returned.

Each command can define its own RATP request contents (e.g. to specify
command-specific options) as well as its own RATP response contents
(if any data is to be returned).

Each command is associated with a pair of numeric unique request and
response IDs, and for easy reference these IDs are maintained in the
common ratp_bb header. Modules may override generic implemented
commands or include their own new ones (as long as the numeric IDs
introduced are unique).

ARM/i.MX53: fix compiler warning ...

The code wants to test if the lower 16bits of the content of
MX53_CSD0_BASE_ADDR and SDRAM_COMPARE_CONST1 are identical. The assembly
this code was derived from did:

	mov             r5, r0, lsl #16
        mov             r6, r7, lsl #16
        cmp             r5, r6

In C this is better written with masks which is better readable and
avoid this compiler warning:

arch/arm/mach-imx/esdctl-v4.c:613:63: warning: result of '305419896 << 16' requires 46 bits to represent, but 'int' only has 32 bits [-Wshift-overflow=]

state: find backend node with its reproducible name ...

When fixing up the kernels state nodes we depended on the full node path
of the input device tree. This does not work when the kernel device tree
has different names. This has happened lately when the i.MX6 device
trees got their leading zeroes removed from the node names.

Use of_find_node_by_reproducible_name() to find the node corresponding
to the storage backend node in the kernel device tree.

DHCP: fix option 54 passing ...

Though variable net_dhcp_server_ip was declared and used as a
function parameter it was never assigned. That's why a DHCP
request was sent without option 54 set. Some DHCP server for
example dnsmasq didn't accept such a packet.

As both offered IP address and server IP are stored in the global
dhcp_result structure we don't need either net_dhcp_server_ip or
OfferedIP variables and can use the addresses from dhcp_result
directly.

According to that code, the RNGC is found on Freescales i.MX3/5 SoCs.
The i.MX2x actually has an RNGB, which has no driver implementation
in Freescales kernel. However as it turns out, the driver for the RNGC
works fine on the (at least) i.MX25. So, they seem to be somewhat
compatible.
