Bluetooth: btintel: Skip reading firmware file version while in bootloader mode

2021-03-25T15:11:12+00:00

This skips parsing the firmware version information from the firmware
file while controller is in bootloader mode. As in bootloader mode,
we are supposed to patch unconditionally.

Bluetooth: btintel: Collect tlv based active firmware build info in FW mode

2021-03-25T15:11:06+00:00

In Operational firmware mode, 'Minimum FW version' TLV ID is not available.
So, we cannot fetch already running firmware info for comparison against
another build. However, It can be collected using a combination of other
TLV ID's information.

Bluetooth: btintel: Reorganized bootloader mode tlv checks in intel_version_tlv parsing

2021-03-25T15:10:53+00:00

This moves limited_cce and sbe_type checks under bootloader during tlv parsing
as operational firmware don't have access to these values. Any attempt to read
such values in operational firmware will only fetch garbage data.

Bluetooth: btintel: Move operational checks after version check

2021-03-25T15:09:41+00:00

In order to allow new firmware to load, it first needs to check if the
firmware version on file matches the one loaded if it doesn't, then it
needs to revert to bootloader mode in order to load the new firmware.

Bluetooth: btintel: Check firmware version before download

2021-03-25T15:09:35+00:00

This checks the firmware build number, week and year against the
repective loaded version. If details are a match, skip the download
process.

Revert "Bluetooth: btintel: Fix endianness issue for TLV version information"

2020-12-18T21:42:42+00:00

This reverts commit a63f23c9d139377833a139b179793fea79ee198f.

get_unaligned_{le16|le32|le64}(p) is meant to replace code of the form
le16_to_cpu(get_unaligned((__le16 *)p)). There is no need to explicitly
do leXX_to_cpu() if get_unaligned_leXX() is used.

do __le32_to_cpu to tlv data fields to make sure driver runs
correctly when running on big endian system.
