Bug Description
Impact:
Although the Bionic/snapdragon kernel contains the BSP from the Qualcomm landing tree kernel[1], it didn't work on Snapdragon 820 based board (e.g. Qualcomm DB820C APQ8096).
Fix:
Import the necessary patches to make it boot on such a board (and clones).
How to test:
1) put the board in fastboot mode (see [2])
2) generate a compatible boot.img:
$ cat linux/arch/
$ touch ramdisk
$ python android/
3) boot the board using the generated boot.img:
$ fastboot boot bionic-
Regression potential:
With new code there's always a degree of regression potential, but all patches (but one) came from Linus's upstream tree, and the only external one, came direclty from the qcom-lt 4.14 tree.
