[Qemu-devel] [PATCH v8 09/11] i.MX25: Add the i.MX25 SOC support |
|
Date: |
Mon, 29 Jun 2015 22:12:09 +0200 |
For now we do support the foolowing devices:
* GPT timers (from i.MX31)
* EPIT timers (from i.MX31)
* CCM (from i.MX31)
* AVIC (from i.MX31)
* UART (from i.MX31)
* Ethernet FEC port
* I2C controller
