Instead the simple fix should be add CONFIG_OF_PRIOR_STAGE to ax25-ae350_defconfig. Then I explain you about that is for booting from flash. And you said In this case, we need support OF_CONTROL like other arch, eg: CONFIG_OF_EMBED and CONFIG_OF_SEPARATE. In README, I don't find the limitation about when booting from flash, it can not use CONFIG_OF_BOARD. That is why ax25-ae350 use CONFIG_OF_BOARD to support boot from RAM and ROM. It is a flexible approach to meet Andes' HW mechanism. I think it is a configuration in ax25-ae350_defconfig. It will not affect qemu-riscv32(64)_defconfig. That is why I do not prepare v2 to modify it as CONFIG_OF_EMBED or CONFIG_OF_SEPARATE as your willingness.

[U-Boot] u-boot bringup on bbb with spi-nor-flash
by C Michael Sundius 28 Nov '18

28 Nov '18

HI guys Please help I've been working on this waaay too long. I have been able to get the most recent u-boot to build with the standard am335x_evm_spiboot_defconfig configuration and it runs on my box... I just changed out the CONFIG_SPI_FLASH_WINBOND with the CONFIG_SPI_FLASH_ISSI to match the flash chip on my board. My goal is to also configure mtd and ubifs on one of the partitions and to load my OS from the UBIFS... I have created the following defconfig, but it doesn't boot.. wondering if anyone out there in u-boot land can take a look and tell me what sort of mistake I've done... really my board is just a BBB with spi flash instead of emmc. any help would be appreciated greatly!!!! this works: am335c_dni_spiboot_defconfig and this one doesn't (with mtd and ubifs) : am335x_dni_defconfig I just pulled the most recent code from git://git.denx.de/u-boot.git master on nov 20....
