hi: I had read some confusing code about io address map in MPC8560 that employs E500 core. My confusion is when io address map is setup, if _PAGE_PRESENT flag of page is set? In implementation of mpc8560 , that seems page flag that maps to io address region is 0x280, means only the following flag is set: #define _PAGE_GUARDED 0x00080 /* H: G bit */ #define _PAGE_NO_CACHE 0x00200 /* H: I bit */
But I think _PAGE_PRESENT shoulbe be set for BOOKE too... /* Definitions for FSL Book-E Cores */ #define _PAGE_PRESENT 0x00001 /* S: PTE contains a translation */ Any guys give me some idea about that? Thanks.... -- Michael.Kang _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
