[coreboot] [ANN] CBMEM console enabled by default; distributors, please rebuild images

[Paul Menzel]

Dear coreboot folks,

thanks to (mainly) Kyösti’s awesome work, CBMEM console [1] is now
enabled by default in the master branch.

So, if you distribute coreboot based firmware and have not enabled these
two options yet, please publish new images from latest master and upload
the board status.

Note, that on AMD AGESA boards, romstage message are still not preserved
in CBMEM.

Please also test change set #8023 [2], Enable COLLECT_TIMESTAMPS by
default, which enables storing time stamps in CBMEM by default.
Currently it fails to build for the mainboards qemu-armv7 and
qemu-riscv.

Thanks,

Paul
