Here it's "strongly recommended" to use SPL FIT support, but not "must", as someone may use U-Boot to execute their own code that wants EL3. In that situation SPL FIT support shouldn't be present. U-Boot is not Linux Loader, so we should give people the permission to disable it; however, U-Boot is mostly used to load and execute Linux, so this should be defaultly enabled -- is this correctly the meaning of defconfig? > > Maxime > > -- > Maxime Ripard, Free Electrons > Embedded Linux and Kernel engineering > http://free-electrons.com _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
