Hi all,
thanks for your quick answer. I wanted to test the u-boot option with coreboot payload on x86 first. So I built coreboot and did a target download with 2 dead devices at the end. I am just about to restore these devices (customized ones) with some difficulties in doing this ;-)...
When I have restored the devices I will continue my u-boot attempts.
I will still have another x86 board soon with Apollo Lake E3950. The board vendor told me that there is really no way to use u-boot as BIOS replacement. Has anyone experience with u-boot and Apollo Lake?
@ Bin and Simon: do you have any idea if u-boot has multiboot2 support? https://www.gnu.org/software/grub/manual/multiboot2/multiboot.html
Best regards Mathias

Hi,
Hi,
I am just about to replace a BIOS based Intel Baytrail E3835 board with
U-Boot due to ugly BIOS boottimes.
Has anyone any experience with this and can give me some tips how to
do this?
Yes, using U-Boot as bootloader (without BIOS or coreboot) is definitely possible for BayTrail boards. And the boot time is definitely much better compared to usual BIOS times. I suggest you take a look at some of the available board ports and the documentation:
doc/README.x86
Minnowboard MAX should be a very good example.
+CC Stefan Roese, IIRC he did something with U-Boot on X86.
Added Bin Meng and Simon Glass, as they did most of the work for x86 U-Boot (also for BayTrail).
Additionally our system runs with an RTS Hypervisor to support 2 OS
in parallel (WIN10, WEC2013).
The Hypervisor runs only on bootloader with multiboot2 support. The bootloader has to load all necessary modules regarding the
multiboot2 specification into storage (License, Configuration, WEC-Image).
Is this possible with u-boot? Has u-boot multiboot2 support?

No idea, sorry. Maybe Bin and / or Simon have some ideas here.
Thanks, Stefan
