No need of your version of U-boot to load BBL. This patchset intend
to follow the standard boot flow.
ZSBL->FSBL->BBL/OpenSBI->U-boot->Linux.
(From ROM)--(M Mode)----(S Mode)-(S Mode)
Couple of Methods to boot Linux:
1. Create a combined image of u-boot and Linux. Give that combined
image as a payload to BBL/OpenSBI. U-boot prompt should appear.
2. Just provide U-boot image as a payload to BBL/OpenSBI.
U-boot prompt should appear. Use TFTP to load Linux.
bootm can be used to boot Linux afterwards.
As of now, there is no SMP support in u-boot. So you may want to bringup
one cpu and test non-smp configuration.
Once we have SPI driver support in U-boot, we should be load images from
MMC as well.
I've been holding off on refactoring or submitting anything
from the MicroSemi U-boot that runs in M-mode and inits the
DRAM until I have some decent method to regression test the
whole system (bootloader, kernel, userspace). I also want
to make sure we don't break any other RiscV platforms when
we add new code.
I am hoping AndesTech guys will give a go at the patchset ;).
It looks HiFive unleashed boards are available for purchase
again, is there any place to get an AndesTech board?
I am not aware of any AndesTech Dev boards.
(fyi, the *proof of concept* hacks for regression testing
that work for me based on MicroSemi patches are at
https://github.com/tmagik/freedom-u-sdk/tree/regression/kernel4.15 )
cool.

This patch adds SiFive FU540 board support. For now, only
SiFive serial, SiFive PRCI, and Cadance MACB drivers are
only enabled. The SiFive FU540 defconfig by default builds
U-Boot for S-Mode because U-Boot on SiFive FU540 will run
in S-Mode as payload of BBL or OpenSBI.
