- * Note: RAMTRON SPI FRAMs are ferroelectric, nonvolatile RAMs

- * busy polls required. They can sustain read or write at the
- * allowed SPI bus speed, which can be 40 MHz for some devices.
- *
- * Unfortunately some RAMTRON devices do not have a means of
- * identifying them. They will leave the SO line undriven when
- * the READ-ID command is issued. It is therefore mandatory
- * that the MISO line has a proper pull-up, so that READ-ID
- * will return a row of 0xff. This 0xff pseudo-id will cause
- * probes by all vendor specific functions that are designed
- * to handle it. If the MISO line is not pulled up, READ-ID
- * could return any random noise, even mimicking another
- * device.
- *
- * We use CONFIG_SPI_FRAM_RAMTRON_NON_JEDEC
- * to define which device will be assumed after a simple status
- * register verify. This method is prone to false positive
- * detection and should therefore be the last to be tried.
- * Enter it in the last position in the table in spi_flash.c!
- *
- * The define CONFIG_SPI_FRAM_RAMTRON_NON_JEDEC both activates
