core: Add hypercall to write to debug console
In order to debug non-root cell boot-strap procedures, it can be helpful
to have a simple and reliable channel for printing messages, and that
independently of passing physical UARTs through or establishing virtual
networks. Such a channel can easily provided via a hypervisor that
writes to the hypervisor's debug console.
However, only invocations from cells which have the explicit permission
via the configuration flag JAILHOUSE_CELL_DEBUG_CONSOLE are executed.
The default remains off, and the administrator is expected to grant this
permission only temporarily while debugging a specific cell.

Log Message:
-----------
tools: Add ARM and ARM64 support to Linux loader script
This extends "jailhouse cell linux" with support for ARM and ARM64
targets. Those need a device tree template to describe the cell, so we
extend the command line options accordingly.
Command line and initrd location/size are passed to the kernel via the
device tree. Therefore, we have to parse the input dtb and patch/extend
it with the required properties under /chosen.
Furthermore, placing the images into the cell memory has arch-dependent
constraints. We need to leave some space (we chose 3-times the kernel
image) between kernel and initrd so that Linux can do decompression and
relocation. And on ARM64, the kernel has to be put on 2 MB-aligned
address plus it load offset.
As we are already patching the dtb, we can also create the /memory node
from the cell configuration. This avoids that config and device tree
have to be manually kept in sync in this regard. Just make sure to not
report any tiny region at the start of address space which we need for
the loader but Linux cannot use and rather get confused by, failing to
boot.

Be less wasteful with memory: provide most of the RAM 1:1 mapped and
report that as available memory via the device tree. Also set
JAILHOUSE_MEM_DMA for the RAM regions, even though we don't have SMMU
support yet, so that the Linux loader script can identify them as RAM.
As jailhouse-cell-linux is now writing the /memory node, we can remove
it from the device tree, instead of updating it.

configs: Add non-root Linux demo cells and device trees for Banana Pi
Use the separate UART 7 for the inmate. Access to the CCU is granted to
allow Linux to enable the related clock gate. We do not control the
access on a bit-level, so this remains a hack. However, we can at least
avoid that Linux touches the wrong bits by describing only the relevant
one in the inmate device tree.
On ARM, we have the need to align the virtual start address of the
identity-mapped memory to 128 MB. Furthermore, Linux won't boot if that
region starts at 0xf0000000 or higher.

We use the same UART for the non-root Linux as the root cell to simplify

To test SMP support, we hand out two CPUs. Note the peculiarity that the
first CPU has to have ID 0 while the second be reported with its real
one, otherwise Linux won't pick up both. Reason is still unclear.
On ARM, we have the need to align the virtual start address of the
identity-mapped memory to 128 MB. Furthermore, Linux won't boot if that

at least from the Jetson as soon as we add SMMU support.

arm, arm64: Fix reset of non-root SMP cells
So far, we initialize cpu_on_entry during arch_cell_create, but not on
arch_cell_reset which breaks the PSCI state after reload and starting a
cell. We can simply move the related code over because arch_cell_create
is issued by cell_start, thus early enough after cell creation. The ARM
and ARM64 implementations of the initialization code look different but
already did the same.
And the bonus is even a few lines of code less.
