These flaws can be *potentially* exploited on any processor that features speculative execution​. No idea as to why there is no comprehensive list of affected CPUs as of yet.
Probably because a comprehensive list would be impossibly long. Anything that does speculative execution combined with caching is likely to be vulnerable. I misspoke a bit ago; branch prediction does not inherently imply speculative execution, but it does imply speculative prefetching. There's some interesting explanatory material on why the ARM11 and Cortex-A7/A53 as used in the Raspberry Pi series are not vulnerable, for example: https://www.raspberrypi.org/blog/why-raspberry-pi-isnt-vulnerable-to-spectre...
