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

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 Author: Kevin O'Connor <kevin(a)koconnor.net> Date: Tue Jul 11 12:09:57 2017 -0400 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.

[PATCH] readserial: allow setting real time timestamps
by Vadim Bendebury (вб) Dec. 18, 2017

Dec. 18, 2017

Sometimes it is beneficial to attach real time stamps to console output, for instance when there is a need to correlate two independently captured logs. This patch adds another command line option (-r,--realtime), when given the generated log is printed with second's resolution real time timestamps.

[PATCH] readserial: allow reading of zero bytes
by Vadim Bendebury Dec. 18, 2017

Dec. 18, 2017

Certain serial device drivers might return without reading anything, returning empty buffer. This is not an indication of the interface being shut down, the readserial utility should keep running.

That check is there because it would not be correct for both an option rom and a native driver to simultaneously attempt to register the same drive. Basically, there can be only one driver for a PCI card - either a native SeaBIOS one or an Option ROM. What happens if you compile SeaBIOS with CONFIG_AHCI disabled? -Kevin
