What's ESP's memory map. where's its reset vectors. where does rom , sram , flash mapped to?

what's its total virtual memory size?

In program what does
void ICACHE_FLASH_ATTR mean? what about rom and sram ATTR?

Why memory mapped to 70000000h? that's 224MB of memory!
No, Esp8266 only has 36KB of internal RAM.
