The errata list is not that much secret. But more like all the
documents that you get from your employer are just under NDA by
default. Even though they might be also available from the other
sources.

I had the same problem. And specifically requested and obtained my
own personal copy of the Cortex-A8 errata list from ARM as a private
individual (to my gmail address, and clearly stating that I wanted it
for the purposes *not* related to my corporate job) :-)

I'm not allowed to share my copy with the other people though, so
everyone has to get it directly from ARM. I believe that that this
only requires filling in the registration form on the ARM website
and agreeing with the conditions.

There are also PDF documents from Freescale in public access, which
contain some Cortex-A8 errata information too:
