Michael (XIAO Xufeng)	fa555e3109	esp_flash: fix a compatibility issue working with the ROM ... The esp_flash API has a side effects: it modifies the clock control registers, and this makes the clock inconsistent with the ROM variable `g_rom_spiflash_dummy_len_plus`. This commit helps the ROM to get the correct dummy cycles required by the latest clock settings. Every device on the SPI1 bus will update the ROM variable when it modifies the clock registers.	2019-07-29 03:00:09 +00:00
