Hi Bin,
From: Bin Meng bmeng.cn@gmail.com Sent: Friday, June 04, 2021 1:51 PM To: Rick Jian-Zhi Chen(陳建志) rick@andestech.com; Leo Yu-Chi Liang(梁育齊) ycliang@andestech.com; U-Boot Mailing List u-boot@lists.denx.de Subject: [PATCH 5/5] riscv: ae350: dts: Add missing "u-boot,dm-spl" for SPL config
At present the AE350 SPL defconfig is using OF_PRIOR_STAGE. The intention was to use gdb to load device tree before running U-Boot SPL/proper from RAM. When we switch to OF_SEPARATE we will have to use our own DT but without "u-boot,dm-spl" in several essential nodes, SPL does not boot.
Can you describe how do you verify and provide the steps about that SPL boot fail that I can duplicate it. :)
Thanks, Rick.
Let's add all the required "u-boot,dm-spl" for SPL config.
