Hi Stefan,
This patch adds support for SAMSUNG's ARM Cortex-A9 based S5P4418
SoC, especially FriendlyARM's NanoPi2 and NanoPC-T2 boards. It is
based on https://github.com/friendlyarm/u-boot/tree/nanopi2-v2016.01.
For v2016.01 I have also made a working SPL (FriendlyARM U-Boot is
using a closed source 2nd-bootloader). My plan is to migrate this
also to the current U-Boot.
Is this somewhat related to Nexell's S5P6818 soc?
There were some patches [1] posted for U-Boot.
Yes, I think the S5P6818 is a follow-up of the S5P4418. Is it planed to
include those patches into U-Boot master? Or is there a branch where
those
patches are already included so I can have a look at it and to be able
to
use those patches where possible?
For the closed source 2nd bootloader - there are some alternatives on
the Internet with a source code [2], [3].
Thanks a lot for the links. I did some research on this subject but I
have not
found any source code for the S5P4418 2ndBootloader. Unfortunately, the
S5P6818 2ndBootloader is not of much use because the initialization of
the
DDR-Ram Controller is different. So I will have a lock at [3].
Issues:
Please send me a value for "#define MACH_TYPE_S5P4418" for
arch/arm/include/asm/mach-types.h.
I think that non-dt device is a no go nowadays... (as we do strive to
switch to DTS as much as possible in U-Boot now).
See my reply to Tom Rini.
The size of the patch is over 700kB, so I will upload it on
http://www.denx.de/wiki/attach/U-Boot/TooBigPatches if not otherwise
instructed.
