#     mtd: spi-nor: aspeed: introduce optimized settings for fast reads
#     
#     Better settings for fast reads are looked for by implementing a SPI
#     Timing calibration sequence described in the Aspeed SoC specification
#     document. The code is based on the OpenPOWER pflash tool and a similar
#     sequence using DMAs can be found in the SDK U-Boot.
#     
#     The SPI calibration performs a loop on different SPI clock rates
#     (dividers of the AHB clock rates) and on different input delay cycles
#     for each SPI clock rates. The successive read results are compared to
#     a golden buffer, read at low speed, to select the fastest read
#     settings for the chip.
#     
#     The "spi-max-frequency" property is used to cap the optimize read
#     algorithm on some devices or controllers for which we want a safe
#     setting, on the FMC controller chips for instance.
#     
#     It can also be deactivated at boot time with a kernel parameter
#     'optimize_read', but that was never used on the field.
