WIMG is an acronym that describes that memory/cache attributes for PowerPC/Power ISA. Each letter of WIMG represents a one bit access attribute, specifically: Write-Through Access (W), Cache-Inhibited Access (I), Memory Coherence (M), and Guarded (G). Web1 0xFFF0_0022 defines a cache-inhibited memory area for instruction cache locking and corresponds to a WIMG of 0b0100. Cache-inhibited memory is not a requirement for data cache locking. A value of 0xFFF0_0002 with a corresponding WIMG of 0b0000 marks the memory area as cacheable. Second 0x0000_0000 256 Mbyte 0b0000 0x0000_1FFF …
