[coreboot] e820 memory map

[Andrew A. I.]

Hello!
Please, someone tell me, why SeaBIOS changing e820 memory map for 0x100000 - 0x7ff2dfff region? For example:

Jun  4 21:41:31 tp0 kernel: [    0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000007ff2dfff] usable

This interrupts the boot from hibernation:

tp0 kernel: [    6.241612] Hibernate inconsistent memory map detected!
tp0 kernel: [    6.243876] PM: Image mismatch: architecture specific data
tp0 kernel: [    6.246132] PM: Read 3253276 kbytes in 0.01 seconds (325327.60 MB/s)
tp0 kernel: [    6.248816] PM: Error -1 resuming
tp0 kernel: [    6.248852] PM: Failed to load hibernation image, recovering.
