Introduction
The purpose of this page is to allow CPUs to be evaluated for suitability for use in FSF-endorsed hardware. Presence or otherwise of a CPU on this page DOES NOT imply that it is an exhaustive list, nor does it imply that each and every CPU is or is not FSF-endorsed. Certain CPUs for example require proprietary libraries for their 3D Graphics, but over time a Free Software compliant alternative may become available, or may be reverse-engineered, in which case CPUs that previously did not qualify suddenly would.
So to be clear: this page is for the PURPOSES of evaluating CPUs, to store research about their present status, NOT to specifically or categorically state "this CPU is endorsed, period".

Notes
- (*1)It is possible to effectively disable any opportunity for the S5PC110 and S5PV210 from being "Treacherous", by blowing an e-fuse. Once "normal booting" has been selected, it is not possible to enable "secure" (Treacherous) booting:
6.1 OVERVIEW OF BOOTING SEQUENCE
S5PC110 consists of 64KB ROM and 96KB SRAM as internal memory. For booting, internal 64KB ROM and
internal 96KB SRAM regions can be used. S5PC110 boots from internal ROM to enable secure booting, which
ensures that the image cannot be altered by unauthorized users. To select secure booting or normal booting,
S5PC110 should use e-fuse information. This information cannot be altered after being programmed.
- (*2)TI CPUs with hardware motherboard to prevent treachery. discussion here
