1 U-Boot for Amlogic P212
2 =======================
4 P212 is a reference board manufactured by Amlogic with the following
7 - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
11 - HDMI 2.0 4K/60Hz display
16 - CVBS+Stereo Audio Jack
18 Schematics are available from Amlogic on demand.
20 Currently the u-boot port supports the following devices:
28 > export CROSS_COMPILE=aarch64-none-elf-
35 Amlogic doesn't provide sources for the firmware and for tools needed
36 to create the bootloader image, so it is necessary to obtain them from
37 the git tree published by the board vendor:

50 Go back to mainline U-boot source tree then :
53 > cp $FIPDIR/gxl/bl2.bin fip/
54 > cp $FIPDIR/gxl/acs.bin fip/
55 > cp $FIPDIR/gxl/bl21.bin fip/
