Hi Scott, > No, MCC1 PRAM starts at offset 0x8700. Any other areas used are under > software control. Yes, you are right. But, I was refereing to MCC channel specific HDLC parameters.
Reason: I am using the MCC2 which uses memory from offset 0x2000 to 0x4000 for Chan Specific parameters. you can see that in MCC chapter i.e. 29.3.1 on a MPC8280 manual. (channel specific HDLC parameters) I need to make sure that cpm_dpalloc is not using this part of DPRAM to allocate memory. I just wanne make sure no other device driver that use cpm_dpalloc to allocate memory for their BDs i.e. scc, smc, fcc. and it looks to me like it is allocating me memory starting from 0x128 or 0x400. > This is obsolete arch/ppc stuff and should be removed; the SMC pram is now > dynamically allocated and relocated (and before that, it came from the > device tree). Yes, I am using 2.6.19.2. I am right now in the middle of finalizing the BSP port. So, I cannot move on further to device trees. I will doing that stuff with in a month but now I am with 2.6.19.2.
