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 04:26:35 -04:00			`# Enable psram cache bug workaround in compiler if selected`

esp32: Rename esp32.common.ld to esp32.project.ld to avoid build errors when downgrading Linker script generator produces build/esp32/esp32.common.ld from components/esp32/ld/esp32.common.ld.in This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and doesn't track build/esp32/esp32.common.ld at all. At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the linker script generated .ld file, which causes mis-builds. As reported on forums: https://esp32.com/viewtopic.php?f=13&t=9684&p=40105 2019-03-13 18:59:31 -04:00			`ESP32_LINKER_SCRIPT_TEMPLATE := $(COMPONENT_PATH)/ld/esp32.project.ld.in`
ldgen: fix build issue on make when build dir is a symlink Fixes an issue where build fails if the build directory is a symlink. The issue is caused by the rule target and the final executable dependency not matching.
