Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Considerations for a long-running Raspberry Pi
Comment by the developer who attempted to create open firmware, https://github.com/christinaa/rpi-open-firmware/issues/37
> a lot of corners were cut to save time leading to what I believe is poor ARMv7+ Cortex IP integration (GIC, TrustZone, etc). So I stopped working on it. If those things were not the case (GIC working, "TZPCs" working, security working as intended, instead of NS forced to high on bridge, at least in my understanding) I would still work on it ...
ARM isn't a second class citizen on this platform, it's a third class citizen since BCM2709 (again this is an opinion) ... the features I wanted to tinker with the most are absent by design (cutting corners) and I'm not willing to resort to SW emulation of them through clever uses of the VPU.

Microsoft opens sources ThreadX RTOS used in Raspberry Pis
Sure, and it's been done: https://github.com/christinaa/rpi-open-firmware - but that doesn't involve ThreadX source, just some standard reverse engineering work. ThreadX is really the least interesting part of this whole operation in terms of the Raspberry Pi.
It's very cool that ThreadX has been open sourced as it offers an additional battle tested and mature alternative to FreeRTOS for new projects, but in terms of reverse engineering or open sourcing the Raspberry Pi VideoCore blob, it's pretty much a non-event IMO.

LibreRPi – open source replacements for RPi firmware
I guess you are thinking of this issue:
https://github.com/christinaa/rpi-open-firmware/issues/37
Since then the project moved to a new maintainer (not me), who worked on it slowly but surely. They need new contributors though.

Using my homemade linux laptop my 70's terminals are able to connect to the interwebs!
They have (https://github.com/christinaa/rpi-open-firmware). The problem is that almost nothing works (no video or even USB). The sequel to "f you, NVIDIA": f you, Broadcom.

SoftBank's Sale of Arm to Nvidia Collapses, Arm to IPO
> no clue if there's a project to reimplement that
There was! And it even booted Linux in some capacity: https://github.com/christinaa/rpi-open-firmware
> every chip is very different from one another
Eh, the usual embedded SoCs are not that different from each other — ARM GIC, ARM timer, lots of Synopsys Designware crap for SDMMC/XHCI/PCIe/etc.
For many SoCs it's totally feasible to make standards-compliant firmware, e.g. for the Rockchip RK3566 there is https://github.com/jaredmcneill/quartz64_uefi
And SoCs from the networking world (Marvell, NXP) are typically supported by upstream EDK2.

Slash CAPEX, OPEX, and Carbon Emissions with T408
Now we turn our attention to carbon emissions which are presented in Table 8. In the table, the AMD – CPU only and AMD – T408 server watts/hour are actual measurements on the test system during operation. To estimate the AWS server watts/hour, we reduced the CPU-only AMD number by 60%, which is the savings that Amazon claims that Graviton3 CPUs provide over other CPUs. In all three cases, we multiplied this by the number of servers, then hours, days, and years, to compute the three-year power consumption total.

Blackberry Partnership Panning Out!
According to BlackBerry, both QNX and IVY can run on EC2 instances powered by AWS’ Graviton2 processor. Graviton2 is an internally-developed processor that AWS debuted at re:Invent last year. It promises to provide up to 40% better price performance than comparable chips. "
