mbedtls: Use hardware accelerated AES, SHA, bignum 2016-09-08 09:41:43 +00:00			`COMPONENT_SRCDIRS := . hwcrypto`

Add wps API 2016-11-07 06:59:35 +00:00			`LIBS := core net80211 phy rtc pp wpa smartconfig coexist wps`
Use IDF_PATH instead of SDK_PATH for the environment variable pointing to esp-idf This will require a matching change in all projects using ESP-IDF. 2016-08-19 06:32:35 +00:00
esp32: Pass memory layout linker script through C preprocessor C preprocessor is a bit icky, but with ULP we will have 3 possible variables influencing the memory layout and 9 linker scripts is too many! 2016-09-21 01:04:16 +00:00			`LINKER_SCRIPTS += -T esp32_out.ld -T esp32.common.ld -T esp32.rom.ld -T esp32.peripherals.ld`

build system: Replace get_variable target w/ component_project_vars.mk generated makefiles Reduces number of make invocations, allows variables exported in project to be seen in all component make processes, not just the main ones.

build system: Refactor SubmoduleCheck to work project-wide Required at project level because some components use header files in other components' submodules, and one component with a submodule (esptool.py) doesn't have or need a component.mk. 2016-11-16 00:12:48 +00:00			`COMPONENT_SUBMODULES += lib`
