In 2012 the Linux Foundation listed Broadcom as one of the Top 10 companies contributing to the development of the Linux Kernel for 2011, placing it in the top 5 percent of an estimated 226 contributing companies. The foundation's Linux Kernel Development report also noted that, during the course of the year, Broadcom submitted 2,916 changes to the kernel. In October, Broadcom released parts of the Raspberry Pi userland under a BSD-style license. According to the Raspberry Pi Foundation, this made it "the first ARM-based multimedia SoC with fully functional, vendor-provided (as opposed to partial, reverse-engineered) fully open-source drivers", although due to substantial binary firmware code which must be executing in parallel with the operating system, and which executes independently and prior to loading of the operating system, this claim has not been universally accepted.
