I think it's not just the SoCFPGA. > That said, I read your comment to mean that the following changes would > work for SoCFPGA: > 1.arch/arm/lib/vectors.S: > #if CONFIG_IS_ENABLED(BOOT0_HOOK) > … pull in the boot0 hook, which needs to contain the vectors > #else > b reset > … remaining vectors … > #endif > 2.boot0.h (for socfpga): > b reset > … remaining vectors … > /* now at 0x40 */ > … whatever currently lives in the boot0.h for socfpga ... > > Ok? I'm not sure I understand what you're trying to say. IIRC the SoCFPGA bootrom checks the content at 0x40-0x48 in SRAM and then jumps to 0x50 if the content is valid. Otherwise it reloads the content from SD/SPI/NAND...
