It is really annoying because most of targets (excepts x86, sunxi, rockchip) do not use dtoc or binman. "checkbinman" and "checkdtoc" are wrong. It is odd that the final build stage checks if we have built necessary tools. If your platform depends on dtoc/binman, you must be able to build pylibfdt. If swig is not installed, it should fail immediately. I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be property select:ed by platforms that need them. Kbuild will descend into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.
