The datasheet for the CY14B101LA device states that the nWE pin should be held high during power up until the MPU comes out of reset. Is it acceptable to hold the nCS pin high during power up until the MPU comes out of reset instead? This would also prevent any unwanted SRAM read or write cycles.
Yes, you are correct. You can pull nCS pin HIGH at power-up which will also prevent any unwanted SRAM read or write cycles. Basically the chip is disabled when nCS is pulled HIGH so this will prevent any read/write to the part.
