[PATCH v3 0/3] hw/ipack: Minor dust removal

[Philippe Mathieu-Daudé]

Clarify what is what in Kconfig,
replace qemu_allocate_irqs() by qemu_init_irq().

Since v2:
- Introduce qemu_init_irqs (Bernhard)

Since v1:
- s/qemu_irq/IRQState/ in IPackDevice state

[PATCH v3 1/3] hw/irq: Introduce qemu_init_irqs() helper

[Philippe Mathieu-Daudé]

While qemu_init_irq() initialize a single IRQ,
qemu_init_irqs() initialize an array of them.

[PATCH v3 2/3] hw/ipack: Clarify KConfig symbols

[Philippe Mathieu-Daudé]

Split IPACK Kconfig key as {IPACK, TPCI200, IP_OCTAL_232}

  - IPack is a bus
  - TPCI200 is a PCI device providing an IPack bus
  - IP-Octal232 is an IPack device plugged on an IPack bus

[PATCH v3 3/3] hw/ipack: Remove legacy qemu_allocate_irqs() use

[Philippe Mathieu-Daudé]

No need to dynamically allocate IRQ when we know before hands
how many we'll use. Declare the 2 of them in IPackDevice state
and initialize them in the DeviceRealize handler.
