[PATCH v2 0/8] Drop support for Renesas H8/300 architecture

Guenter Roeck
2013-08-30T23:51:56Z

H8/300 has been dead for several years, the kernel for it has
not compiled for ages, and recent versions of gcc for it are broken.
It is time to drop support for it.

Yes, I understand it is not that simple to drop an architecture,
and it may need some discussion, but someone has to put a stake
into the ground. Keeping a virtually dead architecture on life support
takes resources which are better spent elsewhere.

v2:
- s/Renesys/Renesas/g
- Found and removed more architecture specific code in fs/minix
and in smc9194 driver
- Added explicit Cc: for h8300 maintainer
- Added subsystem maintainer Acks

----------------------------------------------------------------
Guenter Roeck (8):
Drop support for Renesas H8/300 (h8300) architecture
ide: Drop H8/300 driver
net/ethernet: smsc9194: Drop conditional code for H8/300
net/ethernet: Drop H8/300 Ethernet driver
watchdog: Drop references to H8300 architecture
Drop MAINTAINERS entry for H8/300
Drop remaining references to H8/300 architecture
fs/minix: Drop dependency on H8300
