From c60b835be28a9d6d7a03a64b42a922c08e62530d Mon Sep 17 00:00:00 2001 From: Jonas Karlman Date: Sat, 17 Feb 2024 00:22:39 +0000 Subject: [PATCH] rockchip: rk3328: Add support to build bootable SPI image Similar to RK35xx the BootRom in RK3328 can read all data and look for idbloader at 0x8000, same as it does for SD and eMMC. Use the rksd format and modify the mkimage offset to generate a bootable u-boot-rockchip-spi.bin that can be written to 0x0 of SPI NOR flash.
