* xx30-*-maximized: update flashrom options removing --ifd bios option, keeping whole flash of rom internally. WARNING: ifd needs to be initially unlocked through ifdtool -u on 8mb bottom SPI backup. YOU CANNOT COME FROM 1VYRAIN. IF COMING FROM SKULLS, YOU MUST HAVE RAN OPTIONAL -u OPTION FROM SKULLS. PLEASE UPGRADE ONLY AFTER HAVING A PHYSICAL BACKUP OF BOTH SPI FLASH CHIPS. MORE INFORMATION UNDER https://github.com/osresearch/heads/pull/703. This will guarantee that future flash of produced rom will reflash the ROM totally, where heads make sure of adding users customizations (public key, /etc/config.user) when internally flashed. Unfortunately, if you flash externally, you will have to reinject your public key and readd /etc/config customizations.
* Adding generated bincfg coreboot 4.8.1 patch (merged under coreboot 4.13 and backported here to 4.8.1), resulting in gbe.bin under blobs/xx30/gbe.bin and instructions to replicate in README prior of automation (under repo). Note that MAC under gbe.bin is fixed to DE:AD:C0:FF:EE unless extract.sh script is ran on external backup to keep current user's MAC (Thanks to @Thrilleratplay's contribution!)
* xx30 blobs: add two blobs management scripts for xx30: extract from local backup/download+neuter ME
extract.sh: extract from external backup: gbe.bin, neuter under me.bin and maximize BIOS+reduce ME regions under unlocked ifd.bin.
download_clean_me.sh: download and verify Lenovo latest ME version from website, and drop me.bin in place.
Note: me.bin is 98kb, containing only BUP and ROMP partitions which cannot be modified nor deleted else computer won't boot. As a result, BIOS region is maximized in ifd.bin to 11.5mb and coreboot config takes advantage of that freed space.
* CircleCI: xx30-*-maximized additional step to call download_clean_me.sh prior of building boards so that me.bin is dopped in place. This should be done by users prior of building xx30-*-maximized boards locally, which is imitated in CircleCI builds (look at .circleci/config.yaml for innoextract host added dependency and board buildings. Results on github for each commit).
As part of migration to coreboot 4.12, which includes measured boot
without additional patches, measure all parts of the firmware and the
payload into PCR2.
The same is done in coreboot 4.12. This commit ensures that boards not
migrated yet will show the same behaviour.

These two patches add the capability for coreboot to generate
the RMRR ACPI tables needed for proper IOMMU support. These
patches allow us to use 'intel_iommu=on' vs 'iommu=pt'

crossgcc is now using gcc 8.1.0 which will compile without issues
if your host system has gcc 8.x
This is required if we are to build on a new system (such as latest Fedora)
