MPC 860 boot code
Hi all,
i'm working on a MPC860 boot code software.
I'd like to know the correct initialisation sequence. The one I planned is
=> Set IMMR and MSR
=> Invalidate MMU and cache
=> Set SIU clocks et timers
=> Set memory mapping (load UPM and init Chip Select Bank)
=> Configure MMU
=> activate cache and MMU
=> sonfigure cpm et UART on SMC
Is it a better sequence, easier, more smart ?
