Huh? Much easier to audit a Broadcom SOC? Than what, auditing deliberately obfuscated hardware designs like the modern DirecTV smartcards?
The idea that it's in any sense easy to "audit" the Raspberry Pi's hardware is head-explodey. No you can't.
This is pure back-rationalization. You like the Raspberry Pi. You don't like Intel Corporation. So you come up with a reason why the R-Pi's hardware RNG might be more trustworthy than than the hardware RNG in a modern Intel computer. It's a crazy reason, not least because the R-Pi's core is produced by another giant semiconductor company.
