4bacba431b nvme_drv: do not mask interrupts
During interrupt handling the driver masked and cleared interrupts as
recommended in the spec to prevent spurious or unnecessary interrupts
from occurring.

Due to the way the current implementation operates new Block requests
got submitted while handling completions for already finished ones.
Since interrupts where masked at this point the controller did not
generate interrupts when the newly submitted requests got completed.

As the mask/clear optimization is apparently not strictly needed and
according to the spec undefined when using MSI-X it is removed.

b78b543011 vmm: make ARM VMM configureable
This commit enables users of the VMM to define CPU type and count, RAM size,
kernel and initrd ROM names, GIC version, and Virtio devices to be used.
Derived from the configuration values a flattened device-tree blob (DTB) is
generated and transfered to the VM.

77fc2f1e86 platfrom_drv: map DMA memory non-natural when iommu is present
Consume '<iommu/>' tag from 'devices' report. In case an IOMMU is
present map physical memory to arbitrary locations within IO page table
range 1K-4G. This way every device PD has access to ~4GB of DMA space.

1b66b1bd7c platform_drv: check quota before dma allocations (taken from legacy)
'_env_ram' allocations can lead to
'Expanding_pd_session_client::try_alloc' quota upgrades, which in turn
may lead to a resource request by the platform driver. Therefore, we
check the available quota within the platform driver before allocations.
This is not an optimal solution.

49b4b8597d os/pin_driver: support for time-multiplexed in/out
This patch equips the pin-driver framework with support for the
time-multiplexed operation of a pin as output or input. This is needed
when implementing I2C communication via a bit-banging driver.

To operate pin in both directions, a driver obtains both a pin-state and
a pin-control session for the same pin. The pin-state session can be
used to sense the current pin state. The control session allows the
client to set the pin to high or low (using the 'state' method), or to
set it to high-impedance via the 'yield' method. Once switched to
high-impedance, the pin can be used as input.

01e1e4e5b9 platform_drv: add "leave_operational" attribute
If a device should not be reset, powered off, and its clocks
shall stay untouched when it gets released, the leave_operational
attribute can be set to true in the device node of the related
device inside the devices ROM delivered to the platform driver.
This is useful for drivers, which only enable and initialize
their device, and can be closed afterwards.

cd08cd54a4 usb_block_drv: allow for using UAS devices via BOT
Reintroduce:

USB Attached SCSI devices might expose a bulk-only interface
as fall-back at interface 0 and alternate setting 0. This commit
allows for probing all alternate settings of the active interface
to be able to use such devices.

The configuration was extended so that in case the device interface
is known beforehand the driver can be configured accordingly.

Additionally:

Perform configuration reset upon sessions close in order to bring USB
device to a well defined state.

This approach simplifies future guest code adaption resp. extension,

e052dc282b Revert "nic_router: incremental L4 checksum updates"
This reverts commit 9a37ccfe29 except for the
new declarations in public headers (in order to not change any APIs again).

We revert the commit as we found that there are corner cases in which it
produces a bad UDP checksum. The bad UDP checksum was observed via Wireshark at
a TFTP server in a Sculpt 22.10 Debian 11 VM on the first request of fetching a
file with the TFTP client of the uboot on our iMX8 test board.

c83f307b62 nic_router: consider DHCP client optimization
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.

f59ee209d2 nic_router: use exact packet sizes in dhcp client
The DHCP client used to always send packets with a size of 1024 regardless of
the size of the actual content, which was always significantly lower. 1024
bytes was simply a guess to provide enough space for all types of DHCP client
packets. As we know the exact size of each packet the DHCP client sends even
before packet creation, this commit makes use of the knowledge resulting in
much smaller packets sent by the DHCP client.
