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:

original source, or somewhere else, but it probably should still have the

There are two ways to run into handle_exception, run command 'kgdb' and
encounter a breakpoint which triggers exception handling.

The origin source code only saves regs when first run command 'kgdb'.
Take the following for example, When run 'kgdb', regs is saved to entry_regs.
When run 'bootz', regs is not saved. However, if we set a breakpoint, then
continue. When breakpoint is reached, run `quit`, and Now return to the
instruction which follows kgdb, but not bootz.This may cause errors. So,
save regs for each handle_exception call to return to the correct place.
Example:
Target      |    Host
=>kgdb      |    (gdb)b bootz
            |    (gdb)c
=>bootz     |
            |    (gdb)Here stop because of breakpoint
            |    (gdb)q

U-Boot has imported various source files from other projects,
mostly Linux.

Something like

  #ifdef __UBOOT__
    [ modification for U-Boot ]
  #else
    [ original code ]
  #endif

is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.

Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

When network protocol errors occur (such as a file not being found on a
TFTP server), the processing done by the NetReceive() function will end
up calling the driver's .halt() implementation. However, after that the
device no longer has access to the memory buffers and will cause errors
such as this in the rtl_recv() function when trying to hand descriptors
back to the device:

	pci_hose_bus_to_phys: invalid physical address

This can be fixed by deferring processing of network packets until the
descriptors have been handed back. That way rtl_halt() tearing down
network buffers is not going to prevent access to the buffers.
