[PATCH 0/4] wifi: rtw89: fw: support firmware secure boot

[Ping-Ke Shih]

Firmware secure boot is to ensure firmware running on chip is the one
which is signed and released officially. Without this, it will be failed
to download firmware result from wrong security key data.

The main difference between secure and non-secure boot is content of
secure section, which is one type of many firmware sections, and is to
provide key data.

The basic steps for key data are:
 1. read cryptography method and key_index from efuse (patch 2/4)
 2. parse firmware file to select secure section by the information of
    step 1 (patch 3/4)
 3. download firmware with selected secure section and key data (patch 4/4)

[PATCH 1/4] wifi: rtw89: fw: consider checksum length of security data

[Ping-Ke Shih]

The newer firmware file provides security data with checksum, so we need to
consider the length. Otherwise it will fail to validate total firmware
length resulting in failed to probe.

[PATCH 2/4] wifi: rtw89: fw: read firmware secure information from efuse

[Ping-Ke Shih]

To support firmware secure boot, read secure information from efuse to
know if current hardware module can support secure boot with certain
cryptography method.

This information should be prepared before downloading firmware, so read
efuse right after power on at probe stage. The secure information includes
secure cryptography method and secure key index that are used to choose
proper key material when downloading firmware.

[PATCH 3/4] wifi: rtw89: fw: parse secure section from firmware file

[Ping-Ke Shih]

A firmware file can contains more than one section with secure type, so
use secure information from efuse to choose the one with matched
cryptography method. Then choose key data from MSS poll (multiple security
section pool; see below picture) according to key_index from efuse.

Note that the size of MSS pool isn't included in section size defined
in firmware header, so we also need to parse header of MSS pool to get
its size as shift to parse next section.

If secure boot isn't supported by current hardware, the first secure
section will be adopted, and no need additional process to key data.

[PATCH 4/4] wifi: rtw89: fw: download firmware with key data for secure boot

[Ping-Ke Shih]

Since firmware header contains multiple secure sections, we need to trim
ignored sections, and then download firmware header with single one secure
section.

For secure boot, when downloading secure section, copy security key data
from MSS poll by key_idx read from efuse. If non-secure boot, no need this
extra copy.
