To do this without rebooting the device implement VliUsbhubPdDevice->reload()
like the other FuVliUsbhubDevice child devices.
Fixes half of https://github.com/fwupd/fwupd/issues/2376
Conceptually we were trying to stuff subtly different actions into one vfunc:
* Read firmware from the device to update the verification checksums
* Read a firmware blob from the device for debugging
For the first action we might want to mask out the sections of the flash with
serial numbers (so the verification hashes match the ones published on the LVFS)
and for the second we want just a raw ROM file from the hardware with no
pre-processing that we can compare against an external SPI dumper.
Split out ->dump_firmware to get the raw blob, and allow plugins to also
implement ->read_firmware() if they have to mask out specific offsets or remove
specific images from the FuFirmware container.
In the common case when masking is not required, fall back to using a 'binary'
FuFirmware automatically to make most plugins simpler.
The I²C proxy specification is not always shared with all other devices as
I originally hoped, instead there are other legacy devices that use different
sets of I²C commands.
Un-share various bits of code to allow for additional I²C devices to be added.
No logic changes.
As both hub devices share a FuVliUsbhubDeviceClass instance we cannot 'hijack'
the vfuncs depending on object type. This allows the downstream hub to proxy to
the upstream hub where a GPIOB reset can be performed.
The USB 2.0 controller is used as a 'backup' in case the USB 3.0 firmware fails
to start. Set USB 3 hubs as a greater priority so that the USB 2 ones do not
not get added if the USB 3 firmware is working.
I misunderstood the original specification, and it seems even USB-hub-less
devices have the same header location as their "write-through" counterparts.
The logic was wrong; we should have been using command 0xB0 for attach back to
FW mode for both VL10x and VL103. Using a generic reset on VL103 always reset
the device back into bootloader mode as the ROM signatures were being written
by command 0xC0.
As now attach and detach have different code paths, there's no point having a
`FuVliDevice->reset()` vfunc, and so we can make everything a little simpler at
the same time.
To implement the SPI commands, objects can derive from FuVliDevice and
implement the new vfuncs. This allows us to override the implementation for
minor API changes.
