Hello,

All u-boot ports for the Exynos4412 that I have seen require a proprietary blob for BL1, and many of them also require a proprietary blob for BL2. I'm not seeing any blobs in your 4412 code. Is this because a proprietary blob isn't needed?

Is this is the BL1 blob? https://github.com/xboot/xboot/blob/master/src/arch/arm32/mach-exynos4412/tools/linux/mk4412
