Is there a limit to the number of times write protection can be disabled/enabled on a board, given that the hardware has been sufficiently prepped?
I don't think there is a practical limit. The flash memory itself usually has maximum durability of 10's or 100's of thousands of erase/write cycles. I am not entirely sure about the status register where write protect info is stored, though.
If I use flashrom to disable write protection on a board, then do nothing, then enable write protection again, there shouldn't be any reason I can't just disable write protection again later, correct?
Correct, assuming you do not make changes to the hardware. If /WP is asserted when the write-protect enable bit is set in the status register, then write-protection will be re-enabled. Then you will need to de-assert /WP before clearing the enable bit.
