It's great you want get the board ported to mainline. Me too.
I build the U-boot mainline and uploaded on my espressobin. Used the ATF and WTMI from Marvell.
When I start the flashed .bin file, the U-boot crashed at this following point. "Synchronous Abort" handler, esr 0x96000210
Looks like an issue with SATA - not sure why. You might want to try to disable SATA / AHCI for testing.
Prompt is attached at this mail.
I think there is a problem with the RAM. For example, I build the U-Boot for 1 GB RAM with the Marvell U-boot and the mainline/master. Important constant is DDR_TOPOLOGY=2
make DEBUG=0 USE_COHERENT_MEM=0 LOG_LEVEL=20 SECURE=0 CLOCKSPRESET=CPU_1000_DDR_800 DDR_TOPOLOGY=2 WTP=... BOOTDEV=SPINOR PARTNUM=0 PLAT=a3700 all fip
But when the u-boot mainline starts it promts: U-Boot 2020.04-rc3-00188-g350c44dfb9 (Mar 31 2020 - 10:52:01 +0200)
DRAM: 512 MiB
The Marvell U-boot promts DRAM: 1 GiB
So my question is, where do you define the RAM Size?
Take a look at arch/arm/mach-mvebu/arm64-common.c. Perhaps this code needs some changes for CONFIG_ARMADA_A3700 similar to what is done for CONFIG_ARMADA_8K ?
I suggest you debug in this area a bit to see, where it goes wrong.
At armada-3720-espressobin.dts i expanded the memory size. No success. At mvebu_armada-37xx.h I expand the RAM for two banks. No success.
Or do you see there other problems by starting the mainline?
Thanks, Stefan
