I've checked http://www.coreboot.org/Chromebooks instead of
http://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices,
there are different HP Chromebooks. Falco is the new one, with newer
chips using similar blobs.

Description: PGP signature
X60 has no ME, it's only for devices with newer Intel chipsets (using
the PCH). ME blob is stored in the same Flash chip as the BIOS/coreboot
in newer systems.
Ethernet cards too can have nonfree firmware. It's not normally
updated, while it can have bugs
The HP Chromebook 14 utilizes Coreboot+Seabios and an Atheros AR5B22 which
is, at least somewhat, compatible with ath9k.
It comes with a huawei mu736 3g/hspa module that I personally do not trust
(thus, is disconnected), and requires non-free firmware, as far as I can
tell.
I have found
I have found that the HP Chromebook 14 is just as free as the Gluglug X60
laptop
AFAIK, the Gluglug X60 model has a completely free BIOS, except the Embedded
Controller, which may be a part of the BIOS or not. Chromebooks from Google
have microcode blobs in Coreboot (the BIOS) included,
Gluglug removes the nonfree microcode update that coreboot normally
has.
HP Chromebook 14 (codenamed Butterfly) has these and other blobs:

me.bin is the signed PCH
Can be the Lenovo X201 flashed with Coreboot that does not need me.bin for
its work, if the processor does not include vPro/TXT?
Thank you for the explanation. So, the Management Engine binary is needed
regardless if the processor does support vPro/TXT or not. Am I right?
thank you for showing me those files. just to clarify, is codename Butterfly
the same as codename Falco? This is the exact model name: HP Chromebook
14-q070nr WWAN 4G (ENERGY STAR)
thank you everyone for the explanations.
3 better questions to ask are:
(1) What is non-free about the Gluglug laptops? (So far, I have noted:
Management Engine blob and the Embedded Controller blob; is this all?)
(2) What are potential security privacy vulnerabilities with a user running
