I'm not too familiar with why the kernel firmware stuff gets built but I
suspect it's just because support for a specific driver is compiled in,
or is compiled as a module, so the corresponding fw is built and
packaged/installed when "make modules_install" is run.
Some of the firmwares needed by the drivers are not created as part of the
kernel build. They are binary blobs (often extracted from the Windows
drivers) which get uploaded to the hardware by the Linux kernel drivers to
make the devices operate as intended. As such, the legality of
distributing some of them is a bit dubious.
Is this why for the Globalscale GuruPlug's wifi drivers, I had to copy the
debian /lib/firmware/mrvl files
r...@guruslack:/lib/firmware/mrvl# l
total 512
-rwxr-xr-x 1 root root 2616 2010-05-27 23:54 helper_sd.bin*
-rw-r--r-- 1 root root 278640 2010-05-27 23:54 sd8688.bin

in order to get the wifi access point functionality working? I couldnt find
these in the standard kernel and it kept complaining every time I loaded the
uap8xxx driver that it couldnt find the firmware.
Here is what a good boot looks like after I copied the firmware
[ 59.381185] uap_probe: vendor=0x02DF device=0x9104 class=0 function=1
[ 59.401417] uap_sdio mmc0:0001:1: firmware: requesting mrvl/helper_sd.bin
[ 59.424156] uap_sdio mmc0:0001:1: firmware: requesting mrvl/sd8688_ap.bin
[ 59.718283] UAP FW is active
one set of binaries is for access point, one set is for client (I believe).
My /etc/rc.uap:
#!/bin/sh

# Load the kernel module and configure the access point
