Setup on Banana Pi ARM board
============================
-The Banana Pi is a cheap Raspberry-Pi-like ARM board with an Allwinner A20 SoC (dual-core Cortex-A7).
-It runs mainline Linux kernels and U-Boot and is comparably well hackable. Further information can be found on http://linux-sunxi.org.
-
-In order to run Jailhouse, the Linux kernel version should be at least 3.19.
-The configuration used for continuous integration builds can serve as reference, see `ci/kernel-config-banana-pi`.
-
-Meanwhile, an U-Boot release more recent than v2015.04 is required. Tested and known to work is release v2016.03.
-Note that, **since v2015.10, you need to disable CONFIG_VIDEO in the U-Boot config**, or U-Boot will configure the framebuffer at the end of the physical RAM where Jailhouse is located.
-
-Below is a tutorial about setting up Jailhouse on a **BananaPi M1** board, and running [FreeRTOS-cell](https://github.com/siemens/freertos-cell) on the top of it. The tutorial is based on :

Adjusting U-boot for kernel booting arguments.
---------------------------------------------
-Jailhouse needs to boot with certain Kernel arguments to reserve memory for other cells (using `mem=...`). We must adjust U-boot config file to boot with these arguments.
-The u-boot partition is not mounted by default. Thus, we need to mount it first. On bananian,

Installing Kernel
-----------------
-Here we choose to mount compiled kernel-source directory on BananaPi. Instead one can choose to transfer the directory that contains kernel source to BananaPi.
