List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , I have read in the specs for the MPC8280 that it has a G2_LE core which has 4 additional data and instruction BATs. However, I dont see these BATS being cleared early in the kernel. I only see that the first 4 pairs are cleared using the mtspr instructions. But my kernel comes up just fine and everything seems to work OK. Dont we need to clear the other set of I/DBATS? What happens when we dont do this? Thanks in advance. __________________________________ Do you Yahoo!? The all-new My Yahoo! - Get yours free! http://my.yahoo.com
