Oh good thing, I did not know this patch. Thanks.

By the way, I've tried to get memblock/memory and kernel log from a
device based on
v6.6.17 kernel device, to see upstream patches above.
memblok/memory does not show region for
0x00000000_80000000..0x0x00000000_8195ffff.

   0: 0x0000000081960000..0x00000000819fffff    0 NONE

The kernel log shows information for 0x0000000080000000..0x00000000813fffff=
, but
we don't see information for 0x0000000081400000..0x000000008195ffff
from kernel log.

(I removed the name.)
<6>[    0.000000][    T0] OF: reserved mem:

A smart parser should gather these kernel log and memblock/memory log
and should show
log like my memsize logic shows below.
0x0000000081400000-0x0000000081960000 0x00560000 (    5504 KB ) nomap
unusable unknown

Thank you
