Let's flash multiple copies of UBL and U-Boot to cope better with
NAND bits flipping in these sectors. To fit multiple copies of
U-Boot into the flash we had to move the rootfs a bit to the end.
We do not intend to use u-boot right now but at least this
version will build. In the first version we will use the
barebox images provided to us by the producer of the SoM.
The build differs in that it doesn't use a getty on ttyS0. In the fuutre,
a modified kernel serial driver as well as a 2050-specific utility
for managing the supervisor processor will follow.
The idea is that the basic extension resides inside the the normal
recipe directories. Depending on the version of poky the bbappends
need to be included. Appends applying to all versions will be put
into the shared folder, specific ones into the specific directory.
Once a bbappend can not be shared anymore it needs to be copied.
