Subject: [PATCH v3 12/15] MIPS: jz4740: Drop all obsolete files
Support for Ingenic SoCs is now provided by the arch/mips/generic/ code,
so all files in the arch/mips/jz4740/ folder can dropped, except for the
Kconfig, and the cpu-feature-overrides.h header file.
Signed-off-by: Paul Cercueil <paul@...pouillou.net>
---
Notes:
v2: No change
v3: - Don't rename the folder to ingenic, it will be done in a follow-up patch.
- Don't remove cpu-feature-overrides.h
