Since Linux does not use the arch-independent spinlock structs for ARM,
we must use different members when accessing the lock value.

* Claim and release USB interfaces
* Collect URBs in flight in anchor list
* When releasing interfaces, wait until all
anchored URBs finally got killed successfully

In rare cases it is necessary to execute Linux contributed code
until certain work is finished, e.g. when in a synchronous RPC call,
a session construction or destruction a result is needed. Therefore,
we introduce a new lx_emul function called lx_emul_execute_kernel_until.

In case multiple devices shared the same memory-mapped I/O page
we have to take the offset into account. This commit fixes the
'pc_usb_host_drv' on the Thinkpad X201 where the two EHCI host
controller share the some I/O memory page.
Fixes#4477.
The driver falls in line with the previous 'legacy_wifi_drv' component
where the ported wireless LAN stack and device driver is encapsulated
in a library. This library in return is used by the 'Libc::Component'
providing the necessary environment for the 'wpa_supplicant'.
In constrast to the old driver a 'wifi' VFS plugin is in charge of
initalizing the 'Lx_kit::Env' prior to executing any static
constructors.
Fixes#4455.
Move 'linux-firmware' portion from 'dde_linux' into its own port,
while it is used by the upcoming new WLAN driver keep it in place
for the legacy one.
Issue #4455.
Various libraries, like libnl and wpa_driver_nl80211, used hardcoded
values for the interface index (ifindex) and name (ifname).
To accomdate the legacy as well as the upcoming new driver we add
functions to query these information where at least the index differs.
Issue #4455.
The location of the used 'source.list' file is hard-coded and will not
work when the ported driver is implemented as a shared library. For
this use-case provide means to set the location differently.
Issue #4455.
In case where the ported driver or protocol stack is executed from
an already managed environment, e.g. the libc, the execution
of the static constructors will be performed at the appropriate
time.
Issue #4455.
If any PCI device reports 0 as interrupt PIN, drivers may try to force
MSI setup (e.g., xhci). So, we clamp the interrupt PIN to 1 to let
drivers finish initialization and don't bother the platform driver.
This commit removes all physical notions from the information given
to the Linux kernel regarding PCI BARs.
With the exception for the host bridge that needs to be located at
'0:00.0' as required by the Intel FB driver, all other devices are
announced at the PCI BUS in an ascending order.
Additionally the MMIO regions start at 1 GiB and are capped at 32 bit
to prevent unnecessary access to 64 bit addresses.
.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
