The actual BIOS binary blob hasn't changed, this mainly changes
the command issued through startup.nsh. This command is applicable
to the A20 and A30 platforms as well, so these will be updated
automatically when the new versions come out.
This commit provides two new images for the Netboard A20 BIOS.
Note: the flashtool firmware has changed in such a way that installing
the latest BIOS (version 10) will prevent a user from reverting to
version 9. Therefore two new images for the old version 9 are also
updated here so as to not break backwards compatibility. The checksums
have been updated accordingly
