[PATCH v3 0/4] Consolidate IO memcpy functions

[Julian Vetter]

Fixed compilation problems on 32bit architectures.

Signed-off-by: Julian Vetter <jvetter@xxxxxxxxxxxxx>

---
Changes for v3:
- Replaced again 'if(IS_ENABLED(CONFIG_64BIT))' by '#ifdef CONFIG_64BIT'
  because on 32bit architectures (e.g., csky), __raw_{read,write}q are
  not defined. So, it leads to compilation errors
---
Julian Vetter (4):
  Consolidate __memcpy_{to,from}io and __memset_io into a single lib
  Use generic io memcpy functions on the arm64 architecture
  Use generic io memcpy functions on the csky architecture
  Use generic io memcpy functions on the loongarch architecture
