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
Martin Vychodil	ce28af2dd4	System/memprot: ESP32C3 IRAM section alignment fix (LD) ... IRAM section didn't contain sufficient padding for possible CPU instruction prefetch, ie instruction fetch could happen in DRAM section which is prohibited by the Memprot module. This is fixed by adding 16B to the end of IRAM section in LD script (C3 CPU prefetch buffer depth is 4 words) Closes IDF-3554 * fix	2021-07-23 17:11:12 +02:00
