This does a lot more than add a union :)
I think this looks reasonable, but I would like it even better if this
and related patches could be split up a little bit differently:
- Rename SWITCHTEC_CFG0_RUNNING to SWITCHTEC_GEN3_CFG0_RUNNING, etc
(purely mechanical change, so trivial and obvious).
- Add switchtec_gen and the tests where it's needed, but with only
SWITCHTEC_GEN3 cases for now.
- Refactor ioctl_flash_part_info() (still only supports GEN3).
Maybe adds struct flash_info_regs and union, but only with gen3.
- Add GEN4 support (patch basically contains only GEN4-related
things and doesn't touch GEN3 things at all). Maybe it would
still make sense to split the GEN4 support into multiple patches
(as in this series), or maybe they could be squashed into a single
GEN4 patch?
- It seems like at least the aliasing quirk and the driver device ID
update could/should be squashed since they contain the same
constants.
