Hi.
As you know polarssl was renamed to mbedtls when bought by ARM, this was
circa the 1.3.x release.
Older 1.3.x releases install the library as polarssl alone, newer ones
install dual as polarssl with symlinks to mbedtls (might be the other
way around, i don't recall at the moment - it doesn't matter anyway), so
first the distinction between polarssl and mbedtls is terribly blurred
for the 1.3.x series.
Incidentally this is what makes polarssl 1.2.x being able to live
side-by-side with mbedtls (2.x, which doesn't keep legacy handling) (i
believe this is more product of branding/accident than careful thinking).
So now in some cases polarssl means 1.2.x, in other cases it means
mbedtls 1.3.x, or the new version because nobody cared to rename everything.
Basically any explanation given out of context is useless without
historical context.
Making 1.3.x live side-by-side with mbedtls (let's call it that way for
2+) is probably possible by ditching the new naming and just keeping
compat, i had a look but i think it was a dead end anyway, this requires
patching the build of mbedtls/polarssl 1.3.x somewhat and that wouldn't
be accepted upstream.
Regards.
