New Revision: 10618
URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=10618
Log:
wctdm24xxp, wcte12xp: Allow VPMOCT032 firmware to be compiled into driver.
Enables the driver to update firmware on systems that do not have the firmware
loader configured / enabled (Linux config option CONFIG_FW_LOADER). Compiling
the firmware into the driver increase the memory footprint by around ~440K.
