Hello build bot (Jenkins), Nico Huber, Patrick Rudolph, Angel Pons, Julius Werner, Arthur Heymans, Michael Niewöhner, Kyösti Mälkki, Aaron Durbin, Iru Cai,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/51671
to look at the new patch set (#31).
Change subject: arch/x86: Init firmware pointer for EC SMSC KBC1098/KBC1126 at build time ......................................................................
arch/x86: Init firmware pointer for EC SMSC KBC1098/KBC1126 at build time
According to util/kbc1126/README.md, for these ECs to work, the address and size of their two firmware should be written to $s-0x100` (`$s` means the image size, done with kbc1126_ec_insert), which means that every existing section (especially those used to store code) should not overlap this address, otherwise the bootblock will get damaged when inserting firmwares of the EC.
In this commit, ecfw_ptr is a structure initialized at build time according to CONFIG_KBC1126_FW1_OFFSET and CONFIG_KBC1126_FW2_OFFSET (to do so, they should be redefined as hex), and linked to CONFIG_ECFW_PTR_ADDR within bootblock, so kbc1126_ec_insert is not needed at build time any more.
Test passed on Elitebook Folio 9470m.
