Alexey Lapshin 824c8e0593 feat(esp_system): allow .bss to spill over into L2MEM above 0x4ff40000 ... This commit introduce SOC_MEM_NON_CONTIGUOUS_SRAM flag (that enebled for esp32p4). If SOC_MEM_NON_CONTIGUOUS_SRAM is enabled: - LDFLAGS+=--enable-non-contiguous-regions - ldgen.py replaces "arrays[*]" from sections.ld.in with objects under SURROUND keyword. (e.g. from linker.lf: data -> dram0_data SURROUND(foo)) - "mapping[*]" - refers to all other data If SOC_MEM_NON_CONTIGUOUS_SRAM, sections.ld.in file should contain at least one block of code like this (otherwise it does not make sense): .dram0.bss (NOLOAD) : { arrays[dram0_bss] mapping[dram0_bss] } > sram_low .dram1.bss (NOLOAD) : { /* do not place here arrays[dram0_bss] because it may be splited * between segments */ mapping[dram0_bss] } > sram_high		2024-02-28 19:41:25 +04:00
