Hi Jagon
From: Jagan Teki [mailto:jagan@amarulasolutions.com] Sent: Monday, November 18, 2019 7:30 PM To: Rick Jian-Zhi Chen(陳建志) Cc: u-boot@lists.denx.de; Jagan Teki Subject: [PATCH v4 2/2] sifive: fu540: Enable OF_SEPARATE
Use dts support from U-Boot via OF_SEPARATE instead of depending from opensbi.
This would help to make the necessary changes in drivers and device trees in U-Boot tree itself. This feature would also be helpful to not pass dtb during opensbi builds.

More detailed description of steps required to build FW_PAYLOAD firmware is beyond the scope of this document. Please refer OpenSBI documenation.

I am trying to prepare a PR, but it encounter a conflict with the master when applying this patch. Can you rebase it again ?
Or if you don't mind I can modify your patch directly.
Thanks Rick
