Well, SPI is a hardware shift register with no chance for the slave to
signal whether it's got the data ready or not.  It's well suited to be
implemented in a hardware shift register (like in an FPGA or CPLD) but
not so well suited to be implemented in a controller that takes its
time to prepare the data after asserting the chip select signal.

You could try I²C instead since it allows for the slave to extend the
timing when being overwhelmed by the master.
