Ivan Grokhotkov	1da3204a7c	spiram: expose function to initialize SPI RAM cache ... Some frameworks based on ESP-IDF need to be able to decide whether to initialize SPI RAM after the application has started. This change splits out part of esp_spiram_init which manipulate cache MMU into a separate function. Applications can disable cache, call esp_spiram_init_cache, re-enable cache, and then call esp_spiram_init. Disabling and re-enabling the cache can be achieved using functions provided in esp_spi_flash.h.	2017-10-16 09:15:11 +08:00

Jeroen Domburg	34372a091c	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.	2017-09-04 12:05:49 +08:00
