build system: Refactor component.mk to not need component_common.mk New makefile component_wrapper.mk allows some variables to be set before component.mk is evaluated. This properly fixes problems with sdkconfig being hard to access in all phases of the build. Including component_common.mk is no longer necessary and will print a deprecation warning for components which use it. 2016-11-10 13:20:55 +11:00			`# Main bootloader Makefile.`

Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet. 2017-07-20 16:26:35 +08:00			`$(IDF_PATH)/components/esp32/ld/esp32.rom.spiram_incompatible_fns.ld \`

spi_flash: Fixed bug in SPI flash ROM driver to work with embedded flash chip 1) fixed SPI_read_status: added check for flash busy flag in matrix mode 2) fixed SPI_page_program: enable write before writing data to SPI FIFO 3) SPI flash ROM funcs replacement is controlled via menuconfig option 2017-03-09 10:29:00 +03:00			`ifndef CONFIG_SPI_FLASH_ROM_DRIVER_PATCH`

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. This required cleaning up the way the bootloader project works, it's now mostly independent from the parent. 2017-06-23 14:08:01 +10:00			`COMPONENT_ADD_LDFLAGS += -L $(COMPONENT_PATH) $(addprefix -T ,$(LINKER_SCRIPTS))`
