[U-Boot] [PATCH 2/8] riscv: ax25-ae350: add SPL configuration

Andes uboot at andestech.com
Fri Oct 25 06:10:21 UTC 2019


From: Rick Chen <rick at andestech.com>

This patch provides four configurations
which can support U-Boot SPL to boot from
RAM or FLASH and then boot FIT image
including OpenSBI FW_DYNAMIC firmware
and U-Boot proper images from RAM or
MMC boot devices.

With ae350_rv[32|64]_spl_defconfigs:

U-Boot SPL will be loaded by gdb or FSBL
and runs in RAM in machine mode and then
load FIT image from RAM device on AE350.

With ae350_rv[32|64]_spl_xip_defconfigs:

U-Boot SPL can be burned into SPI flash
and run in flash in machine mode and then
load FIT image from SPI flash or MMC device
on AE350.
