Hi all,

For each NAND_OP_WAITRDY_INSTR operation, the NANDFSR register is
polled only once every 100 us to check for the EMA_WAIT pin. This
isn't frequent enough and causes delays in NAND accesses.

Set the polling interval to 0s. It increases the page read speed
reported by flash_speed by ~40% (~30% on page writes).

I just realized that this SOB should be above the '---'. Sorry about that, I'll send a V2 right away.

Best regards,
