Fwd: [PATCH] spi: zynq_spi: add chip select decoder support

[Nikita Vasilev]

Since zynq_spi device is compatible with Linux Cadence SPI driver, which
supports chip select (CS) decoder, this patch adds the same logic for
u-boot Zynq SPI driver. As a reference, I have used Xilinx Linux kernel
93dc4dbd16d (xilinx-v2020.2).

The SPI decoder feature has been tested on ZynqMP ARM processor and
result has been compared with Linux Cadence SPI driver.
