This patch is simply clean-up to make the IPv4 type that is used match

Previously the net functions would access memory assuming physmem did
not need to be mapped.  In sandbox, that's not the case.

Now we map the physmem specified by the user in loadaddr to the buffer
that represents that space.

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.

When building u-boot as 64 bit application (e.g. sandbox) ulong might be
64 bits in size. This breaks network code as IPaddr_t is 64 bytes in
size then and an IPv4 address is 32 bits in size. This patch makes sure
that IPaddr_t is always 32 bits in size. Also some warnings introduced
by this patch are fixed.

This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI
and code that is compiled when that is not defined.  So here we scrub the

- NfsTimeout() does not correctly update the NFS timeout value which
  results in NfsTimeout() only being called once in certain situations.
  This can result in the 'nfs' command hanging indefinetly.  For
  example, the command:

    nfs 192.168.0.1:/home/user/file

  will not exit until ctrl-c is pressed if 192.168.0.1 does not have an
  NFS server running.

  This issue is resolved by reinitializting the NFS timeout value inside
  NfsTimeout() when a timeout occurs.

- Make the 'nfs' command print the 'T' character when a timeout occurs.
  Previously there was no indication that timeouts were occuring.

- Mimic the 'tftpboot' command and when a download fails print "Retry
  count exceeded; starting again", and restart the download taking the
  'netretry' environment variable into account.

 Minor ./net cleanups - no functional changes
  - change #ifdef DEBUG printf(); #endif to just debug()
  - changed __FUNCTION__ to __func__
  - got rid of extra whitespace between function and opening brace
  - removed unnecessary braces on if statements

 when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3).

Enforce millisecond semantics of the first argument to NetSetTimeout() --
the change is transparent for well-behaving boards (CFG_HZ == 1000 and
get_timer() countiing in milliseconds).

Rationale for this patch is to enable millisecond granularity for
network-related timeouts, which is needed for the upcoming automatic
software update feature.

Summary of changes:
- do not scale the first argument to NetSetTimeout() by CFG_HZ
- change timeout values used in the networking code to milliseconds

Patch by Hiroshi Ito, 06 Dec 2004

  Fix NFS timeout issue

* Increase NFS download timeout (now 1 min - 10 sec is to short for a
  slow download of a big image)

add networking support for VLANs (802.1q), and CDP (Cisco Discovery Protocol)

  - show PCI clock frequency on MPC8260 systems
  - add FCC_PSMR_RMII flag for HiP7 processors
  - in do_jffs2_fsload(), take load address from load_addr if not set
    explicit, update load_addr otherwise
  - replaced printf by putc/puts when no formatting is needed
    (smaller code size, faster execution)

  Fix problems with GCC 3.3.x which changed handling of global
  variables explicitly initialized to zero (now in .bss instead of
  .data as before).

* Patch by Leon Kukovec, 02 Mar 2004:
  add strswab() to fix IDE LBA capacity, firmware and model numbers
  on little endian machines

* Patch by Masami Komiya, 02 Mar 2004:

  - Add verification of RPC transaction ID

* Patch by Pierre Aubert, 02 Mar 2004:
