This series of patches add usage of new memory
attributes EFI_MEMORY_SP and EFI_MEMORY_CPU_CRYPTO,
introduced in UEFI2.8 (mantis 1919 and 1872).
First patch fix typos in description and introduce two
bitmasks for all memory type attributes.
Second and third patches get rid of multiple memory attributes
bitmasks definitions trough multiple files and headers,
and replace them with new common definitions from MdePkg.

I'd suggest posting a v3 patch set, with 4 patches in total: - v4 1/4: equals v3 1/3 - v4 2/4: equals v3 2/3 - v4 3/4: new patch (add WP to EFI_MEMORY_CACHETYPE_MASK) - v4 4/4: v3 3/3, updated The reason for my suggestion is that, once you add EFI_MEMORY_WP to EFI_MEMORY_CACHETYPE_MASK, the present patch will no longer apply verbatim (it will have to be rebased). Namely, the hunk that removes the EFI_MEMORY_CACHETYPE_MASK #define needs to be updated for EFI_MEMORY_WP. When posting v4, please pick up the feedback tags you received during the v3 review. (The small update for the final patch in the series does not invalidate my R-b.) Thank you!
