Angus Gratton	85e76a7cfc	spiflash ROM functions: Remove Quad I/O mode enable/disable code from flash ROM functions Confusion here is that original ROM has two functions: * SPIReadModeCnfig() - sets mode, calls enable_qio_mode/disable_qio_mode * SPIMasterReadModeCnfig() - As above, but doesn't set QIO mode in status register However we never want to use the ROM method to set/clear QIO mode flag, as not all flash chips work this way. Instead we do it in flash_qio_mode.c in bootloader. So in both cases (ROM or "patched ROM") we now call SPIMasterReadModeCnfig(), which is now named esp_rom_spiflash_config_readmode().	2017-04-13 17:54:42 +10:00
