Angus Gratton c38c3ff3f0 spi_flash: Remove 16KB free internal heap limit for esp_flash_read() into PSRAM ... Allocation of the temporary internal buffer will now repeat until a small enough buffer can be allocated, and only fail if less than a 256 byte block of internal RAM is free. Adds unit test for the same, and generic test utility for creating memory pressure.		2020-03-09 09:59:43 +11:00
