[v2] ARM: ixp4xx: Remove unused static map

Commit Message

Linus Walleij Nov. 21, 2022, 10:03 p.m. UTC

The IXP4xx is just using the device tree now, and the UART
static map will be set up by default if .map_io() is not
provided.

Signed-off-by: Linus Walleij <[e-mail]>

ChangeLog v1->v2:
- Realize we can get rid of .map_io() altogether.
