Why was the fifo struct separated from the psc struct for the 5200? I see comments like this now: /* On the 5200, fifo regs are immediately adjacent to the psc regs */ mps->fifo = ((void __iomem *)mps->psc) + sizeof(struct mpc52xx_psc);
Couldn't the fifo struct be a member at the end of the psc struct? /* Structure of the hardware registers */ struct mpc52xx_psc { u8 mode; /* PSC + 0x00 */ u8 reserved0[3]; ...... u8 irmdr; /* PSC + 0x50 */ u8 reserved16[3]; u8 irfdr; /* PSC + 0x54 */ u8 reserved17[3]; struct mpc52xx_psc_fifo fifo; /* like this? */ }; -- Jon Smirl [EMAIL PROTECTED] _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
