ipq806x: Add support for linux-4.4
1)Changes
- Rebased the patches for linux-4.4.7
- Added patch to fix spi nor fifo and dma support
- Added patch to configure watchdog barktime
2)Testing
Tested on IPQ AP148 Board:
a. NOR boot and NAND boot
b. ethernet network and ath10k wifi
c. ubi sysupgrade
UnTested
dwc3 usb has not been validated on IPQ board(AP148)
3)Known Issues:
Once we flash ubi image on AP148, and if we reset the board, uboot on
first boot creates PEB and LEB for dynamic sized partitions, which is incorrect
and not what linux expects which causes errors when trying to mount rootfs.
In order to test this, we can use the below steps:
a. Flash the ubi image on board and don't reset the board
b. load the kernel fit image in RAM and boot from there.
