dc39a8db62 base: introduce Allocator::try_alloc
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.

To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.

d072c408ab dde_linux: call init_page_count for each page
The lx_emul_virt_to_pages implementation initialized the page ref
counter only for the first page, leaving the remaining elements in
uninitialized state. This, in turn, rendered the Linux page_pool (as
used by the emac network driver) ineffective, ultimately leading the a
memory leak. The fix changes the call of 'init_page_count' to take the
loop variable as argument.

c95af254f4 lx_emul: sanitize size 0 for __kmalloc
Driver code such as mfd-core.c may pass 0 as argument n to kcalloc,
which eventually results in an allocation size 0.

  res = kcalloc(cell->num_resources, sizeof(*res), GFP_KERNEL);

Since 'res' is checked against NULL for success, kmalloc must not return
a NULL pointer in this case. The patch works around this issue by
forcing an allocation size of 1 byte in this case.

29032caf40 lx_emul: support CLK_OF_DECLARE initcall mechanism
Clock providers such as drivers/clk/sunxi-ng/ccu-sun8i-r.c don't use
regular init calls but declare their init functions via CLK_OF_DECLARE,
which fill the __clk_of_table. Linux populates the table statically by
using special sections declared in the linker script. In contrast, we
populate the table by expanding the macro to global constructor
functions.

The __clk_of_table is then processed by the call of of_clk_init(NULL).

1a526e73a3 dde_linux: introduce new lx_emul/lx_kit library
The re-newed approach currently supports ARM 64-bit only.
It depends on the Platform API of the ARM architecture.
It tries to meet the original semantic of the Linux kernel
functions as far as possible. To achieve this, device drivers
using this library should reference the original Linux kernel
headers at foremost. Only the headers in `src/include/lx_emul/shadow`
have to shadow clone the original ones.

1aba330ae6 dde_linux: fix packet size calc. of Nic drivers
skb_push() already increases the skb->len by ETH_HLEN, hence adding
ETH_HLEN to the packet_size is redundant.

A too large packet size becomes a problem for large MTUs. With a maximum
MTU of 1500, adding ETH_HLEN twice will lead to a packet size of 1528.
Since this is larger than what we expect for good-old Ethernet (max. 1522),
some clients (e.g. the e1000 model in vbox5) may drop these packets.

ff128df131 dde_linux/fec: fix unsynchronized TX DMA write
Unfortunately, our current implementation of 'wmb()' doesn't seem to do what we
want it to do. On base-hw + imx6q_sabrelite, the write of bdp->cbd_sc seems to
get re-ordered after the write to txq->bd.reg_desc_active in the transmission
path of the contrib code. Due to this, the transmission of the packet is only
triggered the next time a packet is sent. However, we only quick-fix it by
enforcing the execution of the write with a volatile global read as we will
soon update the FEC NIC port with a new DDE approach anyway.

813f4d976b lxip: allocate skb with properly aligned IP header
Comment in Linux sources:

  Since an ethernet header is 14 bytes network drivers often end up with
  the IP header at an unaligned offset. The IP header can be aligned by
  shifting the start of the packet by 2 bytes. Drivers should do this
  with:

  skb_reserve(skb, NET_IP_ALIGN);

This is ensured when using netdev_alloc_skb_ip_align().

dc8c899c1d Streamline platform-device API on ARM
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of

- Platform::Device       - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq  - interface for receiving device interrupts

The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.

0339318572 platform_session: cache arg for alloc_dma_buffer
This patch extends the 'Platform_session::alloc_dma_buffer' interface
with a 'Cache' argument that corresponds to the argument accepted by
'Ram_allocator::alloc', which is used by the platform driver under the
hood.

Since the x86 platform driver used to be hardwired to allocate DMA
buffers as UNCACHED, I adjusted all drivers by specifying the UNCACHED
argument. Right now, this is needed as a hint for core to steer the
allocation of I/O page tables. Once we eliminate the need for such hints
(by introducing an explicit 'Region_map::attach_dma' operation), we can
revisit the drivers individually because cached DMA buffers should
generally be fine on the x86 architecture.

f23e302475 Update OpenSSL to version 1.1.1i
Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.

a6f0b05834 usb_host: properly handle ISOC read requests
* Update the 'packet_size' information with the actual length for
  each isoc frame to be able to handle short reads at the client side.

* Copy the whole transfer buffer because the host controller stores
  the data at the original offsets, i.e., the buffer is not densely
  packed.

Fixes #4018.

23620942bf usb_net: allow calling netif_stop_queue dummy
When the usb_net_drv was introduced in ports/run/netperf.inc, the
netperf_lxip_usb test on x86_64/hw/pc triggered the calling of the
netif_stop_queue dummy at
contrib/<DDE_LINUX>/src/drivers/usb_net/drivers/net/usb/usbnet.c:1464. As
netif_start_queue was also a dummy and allowed to be called, we tried allowing
calls to the netif_stop_queue dummy as well which fixed the
netperf_lxip_usb test on x86_64/hw/pc.
