This patch breaks Tegra (at least Seaboard, and I'd guess all Tegra boards). Reverting it solves the problem. It causes the SPL to be build for ARMv7 even though it should be built for an earlier architecture. I added a $(warning) to arch/arm/Makefile, and it prints: arch/arm/Makefile:37: SPL_BUILD FLAGS -D__ARM__ -marm -mno-thumb-interwork -mabi=aapcs-linux -mword-relocations -mno-unaligned-access -ffunction-sections -fdata-sections -fno-common -ffixed-r9 -msoft-float -pipe -march=armv7-a arch/arm/Makefile:37: SPL_BUILD y FLAGS -D__ARM__ -marm -mno-thumb-interwork -mabi=aapcs-linux -ffunction-sections -fdata-sections -fno-common -ffixed-r9 -msoft-float -pipe -march=armv7-a Note the second line says ARMv7, even though CONFIG_SPL_BUILD is set, so it shouldn't. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
