Hi Roman, The titan_ge.c and titan_ge.h file are still in the kernel, for the Titan chip (Yosemite). Regarding the crash you mention below, kindly use mem=256M in the boot line. The default value of the RAM size is setup to be 512MB and the Sequoia board that you are having may contain only 256MB of RAM. -Raj > -----Original Message----- > From: Roman Mashak [mailto:mrv@xxxxxxxxxxxxx] > Sent: Wednesday, May 31, 2006 6:42 PM > To: Raj Palani > Cc: linux-mips@xxxxxxxxxxxxxx > Subject: Re: compiling BCM5700 driver > > Hello, Raj! > You wrote to "Roman Mashak" <mrv@xxxxxxxxxxxxx>; "Ralf Baechle" > <ralf@xxxxxxxxxxxxxx> on Wed, 31 May 2006 09:06:44 -0700: > > RP> Yes.
