This patch adds support for QCA2066 firmware patch and nvm downloading.
as the RF performance of qca2066 soc chip from different foundries will
be difference, so we use different nvm to configure them by according
to board id.

In the future, it’d be great if you added a change-log between the patch
iterations so reviewers know what to look at.

As the length cannot be negative, why not use `unsigned int`? But also
see below.

Currently, you use `bid_len` only to log it, and not for anything else.
Should some sanity checks be added? Otherwise, I think, the variable can
be removed?

Sorry, I didn’t get to reply to your v3 answer:

> [Tim] you can refer to function qca_uart_setup , which also use u32
I meant `boardid`, which is newly introduced.

For a start, you did not even CC me on v8 so how would I know it exists?
I hope someone has told you before, but you should CC people that have
given you feedback when updating a patch.
Second, the patch is question is missing a changelog describing what has
changed since (all) previous versions, so you'd need to fix that before
I'd look at it again.
