[PATCH v6] Bluetooth: hci_qca: Add support for Qualcomm Bluetooth SoC QCA2066

[PATCH v6] Bluetooth: hci_qca: Add support for Qualcomm Bluetooth SoC QCA2066

[Tim Jiang]

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.

Dear Tim,


Thank you for the patch.

Sorry for getting on your nerves, but how should your implementation be 
reviewed without having information about the different types. Reading 
the code, there is a “g” variant, and the NVM configuration files will 
have the suffix of the board id? Is that correct? It’d be great to have 
this documented in the commit message.

Maybe `unsigned int` as a length cannot be negative.

Maybe add QCA in the front as done below, and separate it by a colon:

QCA: Reading board id failed (%d)

QCA: board ID without header

QCA: wrong packet format for board id

Print it as hex, and also `EDL_CMD_REQ_RES_EVT`, and 
`EDL_GET_BID_REQ_CMD`, so it’s clear which of the two comparisons failed.

Should the length be printed in decimal?

I’d use `unsigend int`.
