Hi, I am newbie to MPC8555, PowerPC family and u-boot. Please guide me.
1. How can I read/write registers from the u-boot similar to md/mm command? Basically I want to read/write CCSR_BAR from the u-boot. 2. How can I read/write CCSRBAR register value from my assembly program? mfspr.mtspr ??? what is the register name?? 3. By changing the default value of 0xFF70:0000 to 0xE000:0000 is sufficient to relocate the 1MB block or anything else is also required? 4. I look at the u-boot code for tqm85xx, 8555cds, and 8555ads series of boards and it does something with TLB. I don't understand why it modifies the TLB registers whose purpose is only for the performance improvement? Or we can use the TLB for something else also?
