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`

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

Build: Handle WiFi & BT enabled/disabled combos gracefully as possible If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack of WiFi. Otherwise linker errors on WiFi symbols should help give a clue as to what is broken. Piggy-backs on changes in !420, ref github #230 #237 2017-01-16 00:52:15 +00:00			`endif`

newlib: add "full" formatting support, add missing functions - add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM. - fix linker error for fmod, fmodf, atof, atoff - update tests 2016-11-07 10:43:29 +00:00			`ifeq ("$(CONFIG_NEWLIB_NANO_FORMAT)","y")`
