The following files have been ported: * esp_rom_crc.h * esp_rom_sys.h * esp_rom_efuse.h (mostly no-ops) * esp_rom_md5.h Integrated Linux-based rom implementation into log and NVS component. Added brief host tests for ROM to ensure basic consistency on Linux. Added ROM printf host unit tests. Temporarily added reset reason for Linux in ROM.
