Missing verb... or enumerated is past tense? I just don't get entire
sentence.

This suggests there is EINT_CON per bank in old and new register layout.
I don't think it's true, so probably this could look like:

| ---                           | 0x18	EINT_CON (per_bank) |
| ---                           | 0x18	EINT_FLTCON0 (per_bank) |
| ---                           | 0x18	EINT_FLTCON1 (per_bank) |
| ---                           | 0x18	EINT_MASK (per_bank) |
| 0x700	EINT_CON (global)       | 0x18	EINT_CON	|

etc..

Also, please use spaces for alignment in the table.
