Our BCM2836 type is really a generic one that can be any of
the bcm283x family. Rename it accordingly. We change only
the names which are visible via the header file to the
rest of the QEMU code, leaving private function names
in bcm2836.c as they are.
This is a preliminary to making bcm283x be an abstract
parent class to specific types for the bcm2836 and bcm2837.

The TypeInfo and state struct for bcm2386 disagree about what the
parent class is -- the TypeInfo says it's TYPE_SYS_BUS_DEVICE,
but the BCM2386State struct only defines the parent_obj field
as DeviceState. This would have caused problems if anything
actually tried to treat the object as a TYPE_SYS_BUS_DEVICE.
Fix the TypeInfo to use TYPE_DEVICE as the parent, since we don't
need any of the additional functionality TYPE_SYS_BUS_DEVICE
provides.

If we're directly booting a Linux kernel and the CPU supports both
EL3 and EL2, we start the kernel in EL2, as it expects. We must also
set the SCR_EL3.HCE bit in this situation, so that the HVC
instruction is enabled rather than UNDEFing. Otherwise at least some
kernels will panic when trying to initialize KVM in the guest.

Add some assertions that if we're about to boot an AArch64 kernel,
the board code has not mistakenly set either secure_boot or
secure_board_setup. It doesn't make sense to set secure_boot,
because all AArch64 kernels must be booted in non-secure mode.
It might in theory make sense to set secure_board_setup, but
we don't currently support that, because only the AArch32
bootloader[] code calls this hook; bootloader_aarch64[] does not.
Since we don't have a current need for this functionality, just
assert that we don't try to use it. If it's needed we'll add
it later.

Code of imx_update() is slightly confusing since the "flags" variable
doesn't really corespond to anything in real hardware and server as a
kitchensink accumulating events normally reported via USR1 and USR2
registers.
Change the code to explicitly evaluate state of interrupts reported
via USR1 and USR2 against corresponding masking bits and use the to
detemine if IRQ line should be asserted or not.
NOTE: Check for UTS1_TXEMPTY being set has been dropped for two
reasons:
1. Emulation code implements a single character FIFO, so this flag
will always be set since characters are trasmitted as a part of
the code emulating "push" into the FIFO
2. imx_update() is really just a function doing ORing and maksing
of reported events, so checking for UTS1_TXEMPTY should happen,
if it's ever really needed should probably happen outside of
it.

The sabrelite machine model used by qemu-system-arm is based on the
Freescale/NXP i.MX6Q processor. This SoC has an on-board ethernet
controller which is supported in QEMU using the imx_fec.c module
(actually called imx.enet for this model.)
The include/hw/arm/fsm-imx6.h file defines the interrupt vectors for the
imx.enet device like this:
#define FSL_IMX6_ENET_MAC_1588_IRQ 118
#define FSL_IMX6_ENET_MAC_IRQ 119
According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf,
page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary,
interrupts are as follows.
150 ENET MAC 0 IRQ
151 ENET MAC 0 1588 Timer interrupt
where
150 - 32 == 118
151 - 32 == 119
In other words, the vector definitions in the fsl-imx6.h file are reversed.
Fixing the interrupts alone causes problems with older Linux kernels:
The Ethernet interface will fail to probe with Linux v4.9 and earlier.
Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe
error handling. This is a Linux kernel problem, not a qemu problem:
the Linux kernel only worked by accident since it requested both interrupts.
For backward compatibility, generate the Ethernet interrupt on both interrupt
lines. This was shown to work from all Linux kernel releases starting with
v3.16.

With the new "--nic" command line parameter option, the "old" way of
specifying a NIC model via the nd_table[] is becoming more prominent
again. But for the pseries "spapr-vlan" device, there is a confusing
discrepancy between the model name that is used for "--device" (i.e.
"spapr-vlan") and the model name that has to be used for "--net nic"
or the new "--nic" parameter (i.e. "ibmveth"). Since "spapr-vlan" is
the "real" name of the device, let's allow "spapr-vlan" to be used
as model name for the nd_table[] entries, too.

the entire page can be registered as a KVM memory slot and make direct

This enables the entire MSIX BAR mapping to the guest for the pseries
platform in order to achieve the maximum MMIO preformance for certain

At the moment we unconditionally avoid mapping MSIX data of a BAR and
emulate MSIX table in QEMU. However it is 1) not always necessary as
a platform may provide a paravirt interface for MSIX configuration;
2) can affect the speed of MMIO access by emulating them in QEMU when
frequently accessed registers share same system page with MSIX data,
this is particularly a problem for systems with the page size bigger
than 4KB.
A new capability - VFIO_REGION_INFO_CAP_MSIX_MAPPABLE - has been added
to the kernel [1] which tells the userspace that mapping of the MSIX data
is possible now. This makes use of it so from now on QEMU tries mapping
the entire BAR as a whole and emulate MSIX on top of that.

At the moment if vfio_memory_listener is registered in the system memory
address space, it maps/unmaps every RAM memory region for DMA.
It expects system page size aligned memory sections so vfio_dma_map
would not fail and so far this has been the case. A mapping failure
would be fatal. A side effect of such behavior is that some MMIO pages
would not be mapped silently.
However we are going to change MSIX BAR handling so we will end having
non-aligned sections in vfio_memory_listener (more details is in
the next patch) and vfio_dma_map will exit QEMU.
In order to avoid fatal failures on what previously was not a failure and
was just silently ignored, this checks the section alignment to
the smallest supported IOMMU page size and prints an error if not aligned;
it also prints an error if vfio_dma_map failed despite the page size check.
Both errors are not fatal; only MMIO RAM regions are checked
(aka "RAM device" regions).
If the amount of errors printed is overwhelming, the MSIX relocation
could be used to avoid excessive error output.
This is unlikely to cause any behavioral change.
