Until now, requesting optional blobs such as 'iwl-debug-yoyo.bin' has
just failed silently. To support desired blobs such as PNVM firmware,
implement the loading of optional firmware while preserving the nowarn
characteristics of the function.
Issue #4663
Try to allocate within constraint area first. In case the area is exhausted,
try allocation at other memory locations.
The motivation for this is to limit DMA allocations to 4GB (since some
devices require addresses below 4GB). On some platforms there is little
physical RAM in this area (<1GB) and the constrainted area exhausts. In
case an IOMMU is present, RAM at higher locations can still be mapped
below 4GB, which is done in the platform drivers.
issue #4665
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.
issue #4665
The platform driver configuration is missing the required 'info'
attribute that allows the 'vesa_fb_drv' to map the proper I/O
memory address of the framebuffer. In addition the driver requires
at least '2' more CAPs, so raise the quota to '110'.
Fixes#4668.
There is one binder with one memory zone per OpenGL context. The patch was
needed before because Genode didn't have proper context support (separate page
tables) leading to binders from one or more context being allocated to the same
GPU address with the same page tables. This was clearly an error and is fixed
with context support.
issue #4664
'_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.

This patch makes the component graph better reusable for the phone
version of Sculpt. In the phone version, the '+' menu does not exist.
So we need to omit the corresponding button. Furthermore, the storage
dialog is presented in a dedicate section of the GUI instead of
presenting it inside the 'storage' graph node. The phone version
also does not offer the inspect view. So we need to omit the
corresponding buttons.
To prevent caching side-effects of USB DMA memory taken from the packet stream
all allocations of USB packets need to be on separated cachelines at least.

To complement the GPIO support allow for setting and reading input
pins. So far this is needed by drivers that attempt to perform I2C
bit-banging via GPIO pins.
Fixes#4624.
In case the allocation fails for the largest possible connector mode,
try smaller modes. Additional add option to specify maximal resolution.
Issue #4659
Increase "assumed" internal kernel memory size based on available memory
to support allocation of framebuffer larger than 16M, which was before
hardcoded.
Issue #4659
When using the newer genode_c_api uplink library, an uplink connection uses
the device name as label, which enables integrators to use different policies
resp. routes for different devices driven by one driver. The nic_drv policy
of the nic_roouter configuration generated by the sculpt_manager however uses
an empty label like: "nic_drv -> ". This is the way how existent NIC drivers,
like ipxe_nic_drv requested their uplink session. To support both driver
variants this commit relaxes the policy by checking for a prefix only.

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.

The tar.gz archive of version 2.4.9 vanished from sourceforge. As the
project moves to GitHub currently and the archive of 2.4.9 is still
available there, just update the download location.
Content and hashes did not change.
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.

With "grub2: update to newer grub2 2.06 version" a regression slipped in
which makes the ISO not bootable on real hardware. The commit reverts to
the previous behaviour, to load the GRUB2 modules after boot later one by
one in the ISO format case.
Fixes#4647
