component/esp32 : fix dualcore bug 1. When dual core cpu run access DPORT register, must do protection. 2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro. 2017-05-08 12:03:04 +00:00			`#ifdef IS_BOOTLOADER_BUILD`

build system: Use component.mk for all components, refactor bootloader build For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1" Also refactored some of the generation of linker paths, library list.
