S3 resume fails on hp/8470p when using SeaBIOS 1.11.0

[Iru Cai]

Hi,

I'm using coreboot with SeaBIOS payload on hp/8470p. I found S3 resume
fails when using the latest SeaBIOS. After testing some revisions of
SeaBIOS, I found this commit is the problem.

commit 04db972290a6f3c61920fc7498031f477911774e

disk: Don't require the 'struct drive_s' to be in the f-segment
> From the cbmem console, when after using SeaBIOS>=commit 04db972, coreboot

cannot find RSDP, thus cannot do the ACPI wakeup.
