I didn't check the fields you've added, but this patch sounds fine.
One thing I did wonder though: rather than naming the reserved registers
1, 2, 3, 4, ... (which must be renumbered any time we add new registers
in the middle of a previously reserved section), perhaps we should name
the reserved registers after the base offset they cover, e.g.:
- u32 reserved1[3]; /* offset 0x24 - 0x2C */
+ u32 reserved24[3]; /* offset 0x24 - 0x2C */
u32 mc_smmu_tlb_flush; /* offset 0x30 */
u32 mc_smmu_ptc_flush; /* offset 0x34 */
- u32 reserved2[6]; /* offset 0x38 - 0x4C */
+ u32 reserved38[6]; /* offset 0x38 - 0x4C */
I presume this isn't necessary for the T124 header since I presume
you've filled out everything from the docs, but perhaps it'd make it
easier to extend this header to future chips assuming the MC register
layout is similar but modified there?
