Support tracing on sandbox by adding suitable CONFIG options. To enable it,
compile U-Boot with FTRACE=1.

The timer functions are marked to skip tracing, since these are called from
the tracing code itself, and we want to avoid an infinite loop.

Add hooks for tracing to generic board, including:

- allow early tracing to start early as possible in U-Boot
- reserve memory for trace buffer
- copy early trace buffer to main trace buffer after relocation
- setup full tracing support after relocation

Use -finstrument-functions when tracing is enabled (make FTRACE=1).
Tracing is not currently supported by SPL even if sufficient memory is
available.

When tracing is enabled, we #define FTRACE. This can be used by
board config files to conditionally enable the tracing options.

Add a library which supports tracing of execution using built-in gcc
features and a microsecond timer. This can be used to record a list of

This patch tackles the time out problem which leads to break the
boot process, when loading file over nfs. The patch does two things.

First of all, we just ignore messages that arrive with a rpc_id smaller
then the client id. We just interpret this messages as answers to
formaly timed out messages.

Second, when a time out occurs we double the time to wait, so that we
do not stress the server resending the last message.
