This patch add functionality to use memory addresses in expressions.
This increases the power of expressions substantially
It adheres to the standard convemtions: memory addresses can be given
in the format *address (e.g. *1000)
Rationale for this change is that it allows masking off bits from a
byte that is obtained by reading data from e.g. i2c.

according to some of the comments the subaddress length is 1 or 2, but we are being
prepared for the case it becomes 3. However the code also accepted 4.
This repairs this by changing the constand 4 to 3.

If a board uses cfb_console driver and splash image
and also defines CONFIG_SILENT_CONSOLE, the user is
locked out even if "silent" is not set. It is not
possible to get any output, neither on vga console
device nor on serial console after redirecting the
output to the serial console, since the GD_FLG_SILENT
flag remains set.
Fix the problem by redirecting the output from frame
buffer to serial console if splashimage is used.
Only suppress the output if "silent" environment
variable was set and don't set the GD_FLG_SILENT
flag arbitrarily.

So far, TFTP negotiated a fixed retransmission timeout of 5 seconds.
In some cases (busy networks, slow TFTP servers) this caused very
slow transfers. A new environment variable "tftptimeout" allows to
set this timeout. Lowering this value may make downloads succeed
faster in networks with high packet loss rates or with unreliable
TFTP servers.

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.
