30 * This file gather function specific to RS600 which is the IGP of
31 * the X1250/X1270 family supporting intel CPU (while RS690/RS740
32 * is the X1250/X1270 supporting AMD CPU). The display engine are
33 * the avivo one, bios is an atombios, 3D block are the one of the
34 * R4XX family. The GART is different from the RS400 one and is very
35 * close to the one of the R600 family (R600 likely being an evolution
36 * of the RS600 GART block).
