It's been decided that TPM mode switching won't be supported
on any other new platforms. Instead of blacklisting the outliers
whitelist the (smaller) list of platforms that do support the
feature.
This is to help break the dependence on the Dell plugin during
initalization.
NOTE: there are corner cases that this plugin will no longer
detect Dell systems now, but these are expected to be rare.
Over the months the original meaning of ALLOW_OFFLINE and ALLOW_ONLINE have be
lost, and there is now a confusing mixture of uses in the source tree. With this
commit we make it clear the UPDATABLE flag is used to specify when the device is
updatable (e.g. from the desktop live session, or from the systemd offline
updates mode, or both) and the NEEDS_REBOOT flag lets us know when the update
is actually going to be done.
For instance, a UEFI UpdateCapsule can be *scheduled* from either the desktop
or from the update mode (but the latter would be a bit weird), but does require
a reboot. Some devices might only be updatable outside the live session, for
instance a hard drive update or a GPU update -- there's just too much going on
with a live session and we want to tightly control what's running during the
firmware flash.
This also means we don't have to "retry" the update when scheduling an update
that really can be scheduled whenever, but just requires a reboot to apply.
This could be used, for instance, to set a property on ThunderBolt controllers
inside Dell computers saying that they support forcing the power level during
coldplug. It could also be used to set the dock type for the synapticsmst hub.
Adding this level of complexity allows us to avoid the creep of HAVE_DELL and
HAVE_LENOVO into seemingly unrelated plugins, and also allows us to have
multiple vendor plugins providing the same end result with two different
vendor-specific mechanisms.
Thunderbolt has a new kernel interface starting from version 4.13,
which simplifies updating the host controller and devices: the
kernel now exposes a sysfs interface for the non-volatile memory
as a device node. This can be used to write the new firmware blob.
Updates are then triggered also via a simple write to a sysfs
file (nvm_authenticate), which in turn is also used for error
reporting.
The plugin should be functionally, but a few items are missing:
- image verification
- safe mode handling
This should hopefully fix the error:
../../checkout/fwupd/plugins/amt/fu-plugin-amt.c:238:1: error: initializer element is not constant

This reverts commit 1a5c7f6fe5.
The warning is obviously complaining that the value cannot be evaluated
at compile time, rather than that it’s being assigned to a const storage
location.
Unfortunately it seems that the definition of UUID_LE is not const (or
not evaluatable as const by the compiler) on a Debian Jessie machine,
which causes compilation to fail with:
../../checkout/fwupd/plugins/amt/fu-plugin-amt.c:238:1: error: initializer element is not constant
const uuid_le MEI_IAMTHIF = UUID_LE(0x12f80028, 0xb4b7, 0x4b2d, \
^
Fix that by dropping the const. Sadness.

When my SNES30 controller was in bootloader mode, it wouldn't update,
and when it was in controller mode, it tried and failed. Now, it prints
out the instructions on how to reset the device if it's in controller
mode, and if it's in bootloader mode, it successfully installs the
firmware update from the .DAT file.
