I went to the samsung tree since the cover letter for this series pointed me there. But I just tried the latest version of this series (v11) using mainlin u-boot. Thanks for the pointer. > See arch/arm/cpu/armv7/exynos/spl_boot.c and tzpc.c for the > TrustZone stuff. OK, thanks. Any pointers on how to get this building with mainline u-boot? Just adding CONFIG_SPL to odroid_xu3.h doesn't seem to work (compile errors.) I'm quite comfortable in the kernel, but I'm not very familiar with u-boot, especially SPL. >> > It takes us back to the 1960s where we sent off our code at night to >> > run it :-) >> > >> > I think the best bet is the current effort to mainline the rest of the >> > Chromebook code then try to build it for XU3. >> >> What's the status of that effort? > > Coming along but the big/little support is still not there.
