[Qemu-devel] [PATCH v13 17/19] i.MX: Add the i.MX25 PDK plateform |
Date: |
Thu, 16 Jul 2015 23:21:52 +0200 |
Tested by booting a minimal Linux system on the emulated platform
Tested by booting the Xvisor hyprvisor on the emulated platform
Signed-off-by: Jean-Christophe Dubois <address@hidden>
---
Changes since v1:
* Added a ds1338 I2C device for qtest purpose.
Changes since v2:
* none
Changes since v3:
* Rework GPL header
* use I2C constructor helper.
Changes since v4:
* use sysbus_create_simple() instead of I2C constructor helper
Changes since v5:
* Add ds1338 only for qtest mode.
* small comment fixes.
Changes since v6:
* Allow for more than 4 serial if suppoted by Qemu.
Changes since v7:
* Move the SOC part into its own file.
Changes since v8:
* rework SDRAM memory initialisation
Changes since v9:
* no change
Changes since v10:
* rename board from 3DS to PDK
* use memory_region_allocate_system_memory()
* rework of memory initialization loop.
Changes since v11:
* no change
Changes since v12:
* no change
