[coreboot] Does S3 work on Haswell boards?

[Аладышев Константин]

I have problem with S3 mode on Haswell board. Everything is fine if S3 time
is very small (<15 seconds), but if it is longer, coreboot won't resume. It
fails on quick_ram_check.

I've enabled mrc.cache and ME in coreboot. I use ME binary from original
board and MRC.bin from Google Panther.

Log from S3 resume:

It seems like DRAM controller and ME are initialized correctly (like in
normal boot), what can be wrong?

Does S3 work on Haswell boards?
