[PATCH 1/2] fbdev: sh_mobile_meram: use ARCH_RENESAS

From: Simon Horman <hidden>
Date: 2016-03-11 02:28:17

Use ARCH_RENESAS in place of ARCH_SHMOBILE.
Also remove spurious ().

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

I would replace SUPERH by ARCH_RENESAS, and thus keep ARCH_SHMOBILE.

"sh_mobile_lcdc_fb" is used on SH_AP325RXA, SH_ECOVEC, SH_KFR2R09, SH_MIGOR,
and SH_7724_SOLUTION_ENGINE, which depend on either CPU_SUBTYPE_SH7722,
CPU_SUBTYPE_SH7723, or CPU_SUBTYPE_SH7724, and all three select ARCH_SHMOBILE.

In addition, it's used on r8a7740/armadillo800eva, which is covered by
ARCH_RENESAS.

As Laurent already pointed out, that one is currently unused.

The MERAM driver isn't used by any ARM platform, you can just drop
ARCH_SHMOBILE completely.
Actually, upon closer inspection, the MERAM driver isn't used by any platform.
If its not used then I think we should consider removing it.

However, it seems to me that its used in the following:

drivers/gpu/drm/shmobile/shmob_drm_crtc.c
drivers/gpu/drm/shmobile/shmob_drm_kms.c
drivers/gpu/drm/shmobile/shmob_drm_plane.c
drivers/video/fbdev/sh_mobile_lcdcfb.c

It seems to me that we would need to either remove usage in the above
files or remove the above files before removing the MERAM driver.

That's correct, those drivers need to be fixed or removed.

Before removing perhaps it makes sense to ask the original author of
the MERAM code about integration status? It may be as simple as
revoking a couple of commits.
