HI Jagan
sorry for the delay response.
And I have checked the maser. There is still a problem with this feature。
reproduce steps: 1. enable the flash protect function 2. using sf cmd to erase the flash. I can get the erase "OK",not the "error".
I think the root cause is that the detection mechanism is missing and to judge the permissions of the action
So pull this PR to improve the erase flow
another question: how can I visit the u-boot-spi/next? do there any link?

When operating the write-protection flash,spi_flash_std_write() and spi_flash_std_erase() would return wrong result.The flash is protected, but write or erase the flash would show "OK".
Check the flash write protection state if the write-protection has enbale before operating the flash.

Does it broken on master? if yes can you check in u-boot-spi/next?
