validity: Add firmware extension upload (Iteration 3)
Implement the firmware extension (fwext) upload module for
Validity/Synaptics VCSFW sensors. When the sensor reports no
firmware loaded (GET_FW_INFO returns status 0xB004), the driver
uploads the .xpfwext firmware file using the following sequence:
1. WRITE_HW_REG32 (0x08) to prepare hardware register
2. READ_HW_REG32 (0x07) to verify register state
3. Load .xpfwext file from filesystem search paths
4. For each 4KB chunk:
a. Send db_write_enable blob (encrypted auth token)
b. WRITE_FLASH (0x41) with chunk payload
c. CLEANUP (0x1A) to commit chunk
5. WRITE_FW_SIG (0x42) to upload RSA signature
6. GET_FW_INFO (0x43) to verify successful upload
7. REBOOT (0x05 0x02 0x00) to activate new firmware
Architecture: Uses the NULL-callback subsm pattern where SEND
states call vcsfw_cmd_send(self, ssm, cmd, len, NULL) and RECV
states read self->cmd_response_status/data directly. This avoids
the double-advance bug with fpi_ssm_start_subsm auto-advancing
the parent.
New files:
- validity_fwext.h: Structures, SSM state enum, API declarations
- validity_fwext.c: Upload SSM, file parser, command builders
- validity_blob_dbe_009a.inc: db_write_enable blob for 06cb:009a
- test-validity-fwext.c: 19 unit tests covering all pure functions
Modified files:
- validity.h: Add cmd_response_status field to FpiDeviceValidity
- validity.c: Add OPEN_UPLOAD_FWEXT state to open sequence
- vcsfw_protocol.c: Save status in cmd_receive_cb for RECV states
- meson.build: Add validity_fwext.c to driver sources
Test results: 34 OK, 0 Fail, 2 Skipped
