From 5e49c5795697868f6317f17fda5a2b04f299e116 Mon Sep 17 00:00:00 2001 From: Ram Chandra Jangir Date: Sat, 21 May 2016 14:48:31 +0530 Subject: 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.
