some items I have found while making my changes to the code.


	In firmware_source/carlfw/src/wlan.c you have aloop to read the TSF 
timer to make sure there is no roll over. According to the docs I have 
when TSF_LOW is read, TSF_HI is automatically concurrently copied to a 
temp register so that an immediate read of TSF_HI will get the value 
that was present when TSF_LO was read.

	Presuming the docs are correct - and this feature is common in 
multi-word timers you should be able to save some code.
	Also with some complex casting or another pointer you can read directly 
to your destination and save a memcpy()

	I beleive the timer_init() routine in carlfw/src/timer.c can not be 
called for more than one timer. Any subsequent call will clear the 
interrupt and mode bits for the previous timer.

	I have not completely tracked these down, but the new config system 
must be missing some dependencies, because I can configure and build 
firmware that will not load.
	In carlfw/src/cmd.c the CARL9170_CMD_PSM case needs ifdef'd with 
CONFIG_CARL9170FW_PSM or it will not build with PSM disabled.
