soc/intel/meteorlake: Generate new TME key on each warm boot
relanding original commit 5013c60a871af8fbce8c38a1c342c454e5b8452f
("soc/intel/meteorlake: Generate new TME key on each warm boot") which was previously reverted by commit 19e66b7c951ce71a1b9bc20158af56e559f8a58f
(Revert "soc/intel/meteorlake: Generate new TME key on each warm boot")
due to consecutive reboot post warm reset issue.
The consecutive reboot post warm reboot issue has been fixed with
commit ba7a9eefcf4e571bc73d4be1141f676fc5547057 ("soc/intel/common: Fix
invalid MADT entries creation"), hence, reattempting to land the original TME key related patch.
BUG=299294328
TEST=Boot up the system, generate kernel crash using following
commands:
$ echo 1 > /proc/sys/kernel/sysrq
$ echo "c" > /proc/sysrq-trigger
System performs warm boot automatically. Once it is booted,
execute following commands in linux console of the DUT and confirm
ramoops can be read.
$ cat /sys/fs/pstore/console-ramoops-0
