Hi, I am wondering what the ramifications of not using the MMU in U-Boot are? I have an MPC8360 (e300 core) where it is capable of disabling the MMU via the MSR[IR] and MSR[DR] bits.
Before disabling the MMU, I'm just wondering why U-Boot bothers to set up the MMU on CPU's that providing disabling of the MMU.
PS I'm not disabling the MMU just for kicks, there are/may be some program-specific scenarios where I may need to use the option of disabling the MMU.
Thanks.
