Devan Lai	b85011c15f	esp32: Add support for noinit variables in SPIRAM ... Add Kconfig option SPIRAM_ALLOW_NOINIT_EXTERNAL_MEMORY When enabled, a new linker script rule (from esp32.extram.noinit.ld) places any variables in the .ext_ram.noinit section in SPIRAM. This section is exempted from the startup SPIRAM memory test and is not zero-initialized or added to the malloc pool, making it usable for noinit variables that persist across reset. The EXT_RAM_NOINIT_ATTR macro places variables in this section.	2021-07-29 10:28:38 +08:00
