[oe] Modifying Ralink RT3070 STA wifi driver for OpenEmbedded

Mon Apr 12 18:08:42 UTC 2010

Hi,
       I would like to modify the Ralink RT3070 STA wifi driver, so that the Makefile can compile with openembedded. 

At the moment, on line 132, I have to explicity set the source path 

LINUX_SRC = /tool/overo-oe/tmp/work/overo-angstrom-linux-gnueabi/linux-omap3-2.6.29-r51/git
CROSS_COMPILE = arm-angstrom-linux-gnueabi-

What modification should I make to the following make file to make it compatible with OpenEmbedded?

Best regards,

Elvis

PS: You can download the driver here:
