The virtex2 FPGA download code watches for init going active during
a download of config data as an error condition. init also goes
active after a configuration is finished in concert with the done
signal. So far, the code does not check for done active until all
of the configuration data is sent. If configuration data has a few
extra pad bytes at the end, this would cause an error message even
though the download had suceeded.
NOTE: virtex2 slave serial and spartan2 versions may still have the
same problem.

Fix "WARNING: flash_make_cmd: unsuppported LittleEndian mode"
message when probing for nonexistent flash in little endian mode.
As a side effect more efficient and smaller code is generated,
which is always a Good Thing (TM).

Use the approved environment variable names. Added "tftpdstp" to
allow ports other than 69 per Tolunay Orkun's recommendation.

Add support for gzip compressed bmp's (CONFIG_VIDEO_BMP_GZIP).
Add support for eeprom write-enable (CFG_EEPROM_WREN).

The global data pointer, stored in r29 before relocation to RAM, was
not initialized to a correct value. This happened because the pointer
declaration was done locally in the scope of the board_init_f()
function. What follows is a cite from gcc.info, 5.37, "Variables in
Specified Registers":
...
The compiler's data flow analysis is capable of determining where
the specified registers contain live values, and where they are
available for other uses. Stores into local register variables
may be deleted when they appear to be dead according to dataflow
analysis. References to local register variables may be deleted
or moved or simplified.
...
Moving the global data declaration to global scope solved the
problem.
- make watchdog driver work on systems with an IPB clock
frequency of 133 MHz (watchdog expired to fast there).
- now all three watchdog chain entries could be used.
- fix some typos.
