[Qemu-devel] [PATCH v2 0/9] Add i.MX6 (Single/Dual/Quad) support

[Jean-Christophe Dubois <jcd@tribudubois.net>]

This patch series adds support for the Freescale i.MX6 processor.

For now we only support the following devices:
* up to 4 Cortex A9 cores
* A9 MPCORE (SCU, GIC, TWD)
* 5 i.MX UARTs
* 2 EPIT timers
* 1 GPT timer
* 7 GPIO controllers
* 6 SDHC controllers
* 1 CCM device
* 1 SRC device
* 3 I2C devices
* various ROM/RAM areas.

This also adds the sabrelite board as a an actual platform for i.MX6.

This series was tested by booting a 4.4 linux kernel (using the
imx_v6_v7_defconfig file as kernel configuration).

Note1: as sabrelite uses uart2 as console, you have to redirect the second
QEMU serial port to stdout.
    qemu-system-arm -M sabrelite -display none ... -serial null -serial stdio

Note2: as the SPI controller is not yet supported in QEMU for i.MX you need
to disable SPI controllers in Linux DTS tree. Otherwise Linux would hang
during the boot waiting for a SPI device to respond.

Note3: You need to disable the GPIO section related to physical push buttons
in the Linux DTS tree in order to avoid excecive interrupt triggering on 
GPIO devices for non existant buttons.

Jean-Christophe Dubois (9):
  i.MX: Allow GPT timer to rollover.
  i.MX: Rename CCM NOCLK to CLK_NONE for naming consistency.
  i.MX: Remove CCM useless clock computation handling.
  i.MX: Add the CLK_IPG_HIGH clock
  i.MX: Add i.MX6 CCM and ANALOG device.
  i.MX: Add i.MX6 System Reset Controller device.
  i.MX: Add i.MX6 SOC implementation.
  i.MX: Add sabrelite i.MX6 emulation.
  i.MX: Add missing descriptions in devices.
