Selecting this option produces: AS arch/arm/boot/compressed/debug.o arch/arm/boot/compressed/debug.S:4:33: fatal error: mach/debug-macro.S: No such file or directory compilation terminated. make[3]: *** [arch/arm/boot/compressed/debug.o] Error 1 The semihosting support cannot be modelled into a senduart macro as it requires memory space for argument passing. So the CONFIG_DEBUG_LL_INCLUDE may not have any sensible value and the include directive should be omitted. While at it, let's add proper semihosting output support to the decompressor.
