It looks like a few companies, including Imagination Technologies, the current company behind MIPS processors, has donated some hardware to the Debian project!

 […] Imagination Technologies recently donated several high-performance SDNA-7130 appliances to the Debian Project for the development and maintenance of the MIPS ports. The SDNA-7130 (Software Defined Network Appliance) platforms are developed by Rhino Labs, a leading provider of high-performance data security, networking, and data infrastructure solutions. With these new devices, the Debian project will have access to a wide range of 32- and 64-bit MIPS-based platforms. […] The Debian project would like to thank Imagination, Rhino Labs and aql for this coordinated donation. […]

PS: I mostly pay attention to Intel and ARM hardware, it’s been a while since I’ve worked on a MIPS box. Just catching up to MIPS after years, there’s a lot of firmware exploit research out there:
