[PATCH v5 0/6] hw/ppc: SPI model

[Chalapathi V <chalapathi.v@linux.ibm.com>]

Hello,

Thank You so much for reviewing patch v4.
In patch v5,
- Added a new commit to remove the dependency from include/hw/ppc/pnv_xscom.h
so that pnv_xscom.h can be included in hw/ssi/pnv_spi.c in PATCH2.
- General comments from Cedric and Glenn were addressed.

The new qom-tree looks like below.
(qemu) info qom-tree 
/machine (powernv10-machine)
  /chip[0] (power10_v2.0-pnv-chip)
    /pib_spic[0] (pnv-spi)
      /pnv-spi-bus.0 (SSI)
      /xscom-spi[0] (memory-region)
    /pib_spic[1] (pnv-spi)
      /pnv-spi-bus.1 (SSI)
      /xscom-spi[0] (memory-region)
    /pib_spic[2] (pnv-spi)
      /pnv-spi-bus.2 (SSI)
      /xscom-spi[0] (memory-region)
    /pib_spic[3] (pnv-spi)
      /pnv-spi-bus.3 (SSI)
      /xscom-spi[0] (memory-region)
    /pib_spic[4] (pnv-spi)
      /pnv-spi-bus.4 (SSI)
      /xscom-spi[0] (memory-region)
    /pib_spic[5] (pnv-spi)
      /pnv-spi-bus.5 (SSI)
      /xscom-spi[0] (memory-region)

(qemu) info qom-tree 
/machine (powernv10-machine)
  /peripheral-anon (container)
    /device[0] (25csm04)
      /WP#[0] (irq)
      /ssi-gpio-cs[0] (irq)

Patches overview in v4.
PATCH1: Remove ppc target dependency from include/hw/ppc/pnv_xscom.h so
        that pnv_xscom.h can be included in hw/ssi/pnv_spi.c in PATCH2.
PATCH2: Create a PNV SPI model and implement configuration unit
        to model SCOM registers.
PATCH3: Extend PNV SPI model: implement sequencer FSM and shift engine.
PATCH4: Add Microchip's SEEPROM 25csm04 model on top of m25p80.
PATCH5: Connect SPI controllers to p10 chip and connect cs lines.
PATCH6: Write a qtest pnv-spi-seeprom-test to check the SPI transactions
        between spi controller and seeprom device.

Test covered:
make check
make check-avocado

Thank You,
Chalapathi
