please add readme files with build instructions like for the ad4630 https://github.com/analogdevicesinc/hdl/blob/ad7616_split_si_pi_v2/projects/ad4630_fmc/zed/README.md

Please update zed/readme file with new parameter, valid values and example(s)

instead of using 0 and 1 to choose the device, could we try using the name? https://github.com/analogdevicesinc/hdl/blob/dev_adaq4224_main/projects/ad4630_fmc/common/ad4x3x_bd.tcl#L95-L102 something like this: ``` switch $S_FPGA_CARRIER { ZCU102 { ... } K26I {...

Please fix conflicts

running "make clean" inside "/hdl/library/spi_engine/interfaces" does not remove .sv files
