88d2198c08 hw/sd: Declare QOM types using DEFINE_TYPES() macro
When multiple QOM types are registered in the same file,
it is simpler to use the the DEFINE_TYPES() macro. In
particular because type array declared with such macro
are easier to review.

Mechanical transformation using the following comby script:

  [pattern-x1]
  match='''
  static const TypeInfo :[i1~.*_info] = {
      :[body]
  };
  static void :[rt1~.*_register_type.](void)
  {
      type_register_static(&:[i2~.*_info]);
  }
  type_init(:[rt2~.*_register_type.])
  '''
  rewrite='''
  static const TypeInfo :[i1][] = {
      {
      :[body]
      },
  };

  DEFINE_TYPES(:[i1])
  '''
  rule='where :[i1] == :[i2], :[rt1] == :[rt2]'

  [pattern-x2]
  match='''
  static const TypeInfo :[i1a~.*_info] = {

f31e8f1318 aspeed/sdhci: Fix reset sequence
BIT(0) of the ASPEED_SDHCI_INFO register is set by SW and polled until
the bit is cleared by HW.

Use the number of supported slots to define the default value of this
register (The AST2600 eMMC Controller only has one). Fix the reset
sequence by clearing automatically the RESET bit.

668f62ec62 error: Eliminate error_propagate() with Coccinelle, part 1

propagating to somewhere else, we can just as well receive it there

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

         if (fun(args, &err)) {
             goto out
         }
         ...
     out:
         error_propagate(errp, err);

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly.  I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err".  For
an example where it's too narrow, see vfio_intx_enable().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

5325cc34a2 qom: Put name parameter before value / visitor parameter
The object_property_set_FOO() setters take property name and value in
an unusual order:

    void object_property_set_FOO(Object *obj, FOO_TYPE value,
                                 const char *name, Error **errp)

Having to pass value before name feels grating.  Swap them.

0e2c24c626 hw/sd: Configure number of slots exposed by the ASPEED SDHCI model
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.

The existing code assumed that the SD controller always provided two
slots. Rework the SDHCI object to expose the number of slots as a
property to be set by the SoC configuration.
