lsefimmap: support persistent memory and other UEFI 2.5 features
...
This should accompany
76ce1de740
Translate UEFI persistent memory type
1. Add a string for the EfiPersistentMemory type 14 that was
added in UEFI 2.5.
2. Decode the memory attributes that were added in UEFI 2.5:
* NV (non-volatile)
* MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
with partial memory mirroring)
* RO (read-only)
3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
values rather than misusing SI power-of-ten units (KB, MB, etc.)
4. The lsmmap command only decodes memory ranges sizes up to GiB scale
units. Persistent memory ranges will reach into the TiB scale.
Since 64-bit size field supports TiB, PiB, and EiB, decode all of
them for completeness.
5. In the lsefimmap command, rewrite the print statements to
* avoid rounding
* avoid a big nested if/else tree.
For example: In the sixth entry below, the value of 309MB implies
316416KB but is really reporting 316436KB.
Widen the size column to 6 digits to accommodate typical cases.
The worst case value would require 14 digits; if that happens,
let the columns get out of sync.
