Michael (XIAO Xufeng)	dc26065a72	esp_flash: fix the regression of non-quad mode by default chip driver The issue is introduced in `571864e8ae`. The esp_flash API tries to clear the QE bit when the flash is not working in quad modes. However this introduces a regression, compared to earlier versions and the legacy API. When the chip is not detected, the generic chip driver is used, which cannot 100% handle the QE bit properly for all flash vendors. There may be some flash chips (e.g. MXIC) that can be used in dual modes by legacy API, but output wrong data when the esp_flash API clears the QE bit in a wrong way. This commit reverts the QE force clearing behavior, so that it's safer for the generic chip driver to work under dual modes.	2020-04-17 18:15:31 +08:00
Michael (XIAO Xufeng)	3b429766bc	esp_flash: support MXIC flash chips The default chip driver (chip_generic) use command 01H + 2 bytes to clear the QE bit. However this will accidently change the configuration register value of the MXIC chip. MXIC chip driver is added to fix that.	2020-04-01 20:54:23 +08:00
