I can find one other report like that: https://lkml.org/lkml/2013/7/16/309
[ 0.000000] efi: Could not reserve boot range [0x0000000000-0x0000000fff]
efi: mem00: type=3, attr=0xf, range=[0x0000000000000000-0x0000000000001000) (0MB)
which is EFI_BOOT_SERVICES_CODE and
efi: Could not reserve boot range [0x000005f000-0x000009ffff]
efi: mem06: type=3, attr=0xf, range=[0x000000000005f000-0x00000000000a0000) (0MB)
which is of the same type.
