This enables qemu to handle late inits and report errors. All the SSI
slave routine names were changed accordingly. Code was modified to
handle errors when possible (m25p80 and ssi-sd)
Tested with the m25p80 slave object.

Define some macros that can be used for defining registers and fields.
The REG32 macro will define A_FOO, for the byte address of a register
as well as R_FOO for the uint32_t[] register number (A_FOO / 4).
The FIELD macro will define FOO_BAR_MASK, FOO_BAR_SHIFT and
FOO_BAR_LENGTH constants for field BAR in register FOO.
Finally, there are some shorthand helpers for extracting/depositing
fields from registers based on these naming schemes.
Usage can greatly reduce the verbosity of device code.
The deposit and extract macros (eg FIELD_EX32, FIELD_DP32 etc.) can be
used to generate extract and deposits without any repetition of the name
stems.

Add memory io handlers that glue the register API to the memory API.
Just translation functions at this stage. Although it does allow for

This API provides some encapsulation of registers and factors out some
common functionality to common code. Bits of device state (usually MMIO
registers) often have all sorts of access restrictions and semantics
associated with them. This API allows you to define what those
restrictions are on a bit-by-bit basis.
Helper functions are then used to access the register which observe the
semantics defined by the RegisterAccessInfo struct.
Some features:
Bits can be marked as read_only (ro field)
Bits can be marked as write-1-clear (w1c field)
Bits can be marked as reserved (rsvd field)
Reset values can be defined (reset)
Bits can be marked clear on read (cor)
Pre and post action callbacks can be added to read and write ops
Verbose debugging info can be enabled/disabled
Useful for defining device register spaces in a data driven way. Cuts
down on a lot of the verbosity and repetition in the switch-case blocks
in the standard foo_mmio_read/write functions.
Also useful for automated generation of device models from hardware
design sources.

It doesn't make sense to pass a NULL ops argument to
memory_region_init_rom_device(), because the effect will
be that if the guest tries to write to the memory region
then QEMU will segfault. Catch the bug earlier by sanity
checking the arguments to this function, and remove the
misleading documentation that suggests that passing NULL
might be sensible.

Provide a new helper function memory_region_init_rom() for memory
regions which are read-only (and unlike those created by
memory_region_init_rom_device() don't have special behaviour
for writes). This has the same behaviour as calling
memory_region_init_ram() and then memory_region_set_readonly()
(which is what we do today in boards with pure ROMs) but is a
more easily discoverable API for the purpose.

The "ICP" is a different object than the "XICS". For historical reasons,
we have a number of places where we name a variable "icp" while it contains
a XICSState pointer. There *is* an ICPState structure too so this makes
the code really confusing.
This is a mechanical replacement of all those instances to use the name
"xics" instead. There should be no functional change.

Calling our function g_list_insert_sorted_merged is a misnomer,
since we are NOT writing a glib function. Furthermore, we are
making every caller pass the same comparator function of
range_merge(): any caller that would try otherwise would break
in weird ways since our internal call to ranges_can_merge() is
hard-coded to operate only on ranges, rather than paying
attention to the caller's comparator.
Better is to fix things so that callers don't have to care about
our internal comparator, by picking a function name and updating
the parameter type away from a gratuitous use of void*, to make
it obvious that we are operating specifically on a list of ranges
and not a generic list. Plus, refactoring the code here will
make it easier to plug a memory leak in the next patch.
range_compare() is now internal only, and moves to the .c file.

g_list_insert_sorted_merged() is rather large to be an inline
function; move it to its own file. range_merge() and
ranges_can_merge() can likewise move, as they are only used
internally. Also, it becomes obvious that the condition within
range_merge() is already satisfied by its caller, and that the
return value is not used.
The diffstat is misleading, because of the copyright boilerplate.

Currently vmport device is identified by the string literal. Using a
preprocessor alias instead is preferable.

The speaker device needs pointer to ISA PIT device to operate. But according to
qdev-properties.h, properties of pointer type should be avoided. It seems a
link type property is a good substitution.

The num_queues field is always 1 for the time being. A later patch will
make it a configurable device property so that multiqueue can be
enabled.

Use socket_*() functions from include/qemu/sockets.h instead of
listen()/bind()/connect()/parse_host_port(). socket_*() fucntions are
QAPI based and this patch performs this api conversion since
everything will be using QAPI based sockets in the future. Also add a
helper function socket_address_to_string() in util/qemu-sockets.c
which returns the string representation of socket address. Thetask was
listed on http://wiki.qemu.org/BiteSizedTasks page.

By specifying the silicon revision we select the appropriate reset
values for the SoC.
Additionally, expose hardware strapping properties aliasing those
provided by the SCU for board-specific configuration.

The SCU is a collection of chip-level control registers that manage the
various functions supported by ASPEED SoCs. Typically the bits control
interactions with clocks, external hardware or reset behaviour, and we
can largly take a hands-off approach to reads and writes.
Firmware makes heavy use of the state to determine how to boot, but the
reset values vary from SoC to SoC (eg AST2400 vs AST2500). A qdev
property is exposed so that the integrating SoC model can configure the
silicon revision, which in-turn selects the appropriate reset values.
Further qdev properties are exposed so the board model can configure the
board-dependent hardware strapping.
Almost all provided AST2400 reset values are specified by the datasheet.
The notable exception is SOC_SCRATCH1, where we mark the DRAM as
successfully initialised to avoid unnecessary dark corners in the SoC's
u-boot support.
