When a sub-module doesn't contain any definitions, we don't generate
code for it, but we do generate the #include.
We generate code only for modules that get visited.
QAPISchema.visit() visits only modules that have definitions. It can
visit modules multiple times.
Clean this up as follows. Col

Having to include qapi-commands.h just for qmp_init_marshal() is
suboptimal. Generate it into separate files. This lets
monitor/misc.c, qga/main.c, and the generated qapi-commands-FOO.h
include less.

Modules are represented only by their names so far. Introduce class
QAPISchemaModule. So far, it merely wraps the name. The next patch
will put it to more interesting use.
Once again, arrays spice up the patch a bit. For any other type,

Hi,
Here is a short series adding :
- a new eMMC controller model for the AST2600 SoC (Andrew)
- accessors to control the led state of the pca9552 device (Joel)
- a 'execute-in-place' property to boot directly from CE0
Thanks,

The AST2600 includes a second cut-down version of the SD/MMC controller
found in the AST2500, named the eMMC controller. It's cut down in the
sense that it only supports one slot rather than two, but it brings the
total number of slots supported by the AST2600 to three.

Initialise another SDHCI model instance for the AST2600's eMMC
controller and use the SDHCI's num_slots value introduced previously to
determine whether we should create an SD card instance for the new slot.

The overhead for the OpenBMC firmware images using the a custom U-Boot
is around 2 seconds, which is fine, but with a U-Boot from mainline,
it takes an extra 50 seconds or so to reach Linux. A quick survey on
the number of reads performed on the flash memory region gives the
following figures :

These buffers should be aligned on 16 bytes.
Ignore invalid RX and TX buffer addresses and log an error. All
incoming and outgoing traffic will be dropped because no valid RX or
TX descriptors will be available.

Since io_uring is the actual name of the Linux API, we use it as enum
value even though the QAPI schema conventions would prefer io-uring.
