OK. I think it's more just "standalone U-Boot" that "standalone U-Boot with this load address" then. I think the difference is that when running as a second stage under fastboot, U-Boot might get loaded on the A9 rather than the AVP, so the ARM ISA of the AVP doesn't come into play, and Tom Warren said he thought that USE_PRIVATE_LIBGCC=yes was only needed due to the AVP's ARM ISA difference. > The reason for including this in the > commit message was that it isn't documented anywhere else and I wanted to > avoid a situation where this question needs to be answered over and over. > > Perhaps the commit message is not the best place, but I would still like to > have this documented somewhere. Any suggestions? Can this option be selected by include/configs/tegra2-common.h? I suspect not since it's more of a make variable. Perhaps it can be forced on by a Tegra-specific makefile such as arch/arm/cpu/armv7/tegra2/config.mk or arch/arm/cpu/armv7/tegra2/Makefile? Then it wouldn't need to be documented; it'd be automatic. -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
