2021-12-21arch/x86: Init firmware pointer for EC SMSC KBC1098/KBC1126 at build timeBill XIE
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.

2021-01-08cbfstool: Use flock() when accessing CBFS filesJulius Werner
Trying to do multiple operations on the same CBFS image at the same time likely leads to data corruption. For this reason, add BSD advisory file locking (flock()) to cbfstool (and ifittool which is using the same file I/O library), so that only one process will operate on the same file at the same time and the others will wait in line. This should help resolve parallel build issues with the INTERMEDIATE target on certain platforms. Unfortunately, some platforms use the INTERMEDIATE target to do a direct dd into the CBFS image. This should generally be discouraged and future platforms should aim to clearly deliminate regions that need to be written directly by platform scripts with custom FMAP sections, so that they can be written with `cbfstool write`. For the time being, update the legacy platforms that do this with explicit calls to the `flock` utility.

For mainboards using the HP KBC1126 EC interface, but with a different EC implementation, we don't put the EC firmware in the CBFS image. Add a Kconfig option to prevent the build system warning on not inserting the EC firmware.

The build system still builds a working coreboot image for EliteBook 2560p, and gives a warning if not choosing to insert the EC firmware.
