For linux to boot you need fdt (i.e. device tree) hence use of FDT_SRC is to prove device tree. BOOTARGS are used to pass booting arguments (like which console to use what is root device ? etc..). Boot wrapper adds/fills these BOOTARGS inside "chosen" node of fdt selected. > > > Thanks > > Xiaoke Wu > Thanks, Pranav > > _______________________________________________ > linaro-dev mailing list > linaro-dev@lists.linaro.org > http://lists.linaro.org/mailman/listinfo/linaro-dev _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
