Anybody, I am porting U-boot to a new custom MPC8360E based board. I have downloaded the GIT U-boot tree, and see that DENX has made an example for the MPC8360E-MDS board, and it is an excellent start. <If anyone is interested I have the new 83xx header files to support Rev 2.0 CPU's, only about 10 extra lines>
My question lies with what value to place in the CFG_INIT_RAM address. I see that the example board has this mapped to dcache? I think... If so how does one calculate what address dcache sits at? Or would I be able to use the internal IMMR space multi-user QE ram? My question is without dissecting the assembly at startup, does the IMMR get remapped before or after the CFG_INIT_RAM is used. The board has no external memory other than DDR, so I am going to have to use something in the CPU. Due to the massive amount of flash on our board <128M>, I cannot leave the .text space at 0xFE00000. So I would prefer the IMMR be located at 0xF0000000 and flash be at 0xE0000000, this would leave room for future expansion <maybe up to 256M>, if this is even related to early startup. -Russ _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
