30U-Boot compilation
31==================

33 > export ARCH=arm
34 > export CROSS_COMPILE=aarch64-none-elf-
35 > make khadas-vim_defconfig
36 > make

38Image creation
39==============
40
41Amlogic doesn't provide sources for the firmware and for tools needed
42to create the bootloader image, so it is necessary to obtain them from
43the git tree published by the board vendor:

56Go back to mainline U-Boot source tree then :
57 > mkdir fip
