Grant,
We don't need to change anything in the UEFI Spec. All we need to do is to request the addition of /Firmware directory in the registry. You can send the request to the USWG chair. There is a link on that page to send the request.
Okay, I'll do that.
Created a github issue to track the topic:

Vendors do have the freedom to choose a name, but the name needs to be requested to the USWG chair so that USWG can check whether the name collides with any existing names and whether the request is legit. Sometimes vendors may need to change the proposed name if it collides with the existing one.

Grant,
In section 4.2, the /Firmware directory is mentioned. What are the reasons why this new hierarchy of directories are created? Can we not use the existing /EFI hierarchy as shown at http://www.uefi.org/registry? I may have missed the rational when discussed.
Because it doesn't contain EFI executables, or have anything to do with the UEFI spec at all. A different hierarchy was selected because it insulates firmware implementation details from the hierarchy used by an OS to install EFI binaries.
If we do need to create a new /Firmware hierarchy, we need to register that with the UEFI Forum as the UEFI Forum owns the ESP name space to avoid conflicts. EBBR cannot single-handedly create new hierarchy.
I'm okay with that. Care to propose suitable language for the EFI spec?
Also, each SoC vendor would need to make request to the UEFI Forum to get their vendor subdirectories under /Firmware as well.
Is that true? I lifted the description of the /FIRMWARE directory straight from UEFI section 13.3.1.3:
"Applications that are loaded by other applications or drivers are not required to be stored in any specific location in the EFI system partition. The choice of the subdirectory name is up to the vendor, but all vendors must pick names that do not collide with any other vendor’s subdirectory name. This applies to system manufacturers, operating system vendors, BIOS vendors, and third party tool vendors, or any other vendor that wishes to install files on an EFI system partition."Seems to me that the vendors have freedom to chose a name.

I've tagged the prerelease in preparation for a wider v0.6 RFC release next week. Please review and comment:
https://github.com/glikely/ebbr/releases/tag/v0.6-pre1
(I've linked to the copy on my personal ebbr fork because I'm having trouble getting Travis-ci to deploy to the official repo. It will take a bit of effort to work out what is wrong)
