The S25HL-T/S25HS-T family is the Cypress Semper Flash with Quad SPI.
The datasheets can be found in the following links.

https://www.cypress.com/file/424146/download (256Mb/512Mb/1Gb, single die)
https://www.cypress.com/file/499246/download (2Gb/4Gb, dual/quad die)

Tested 512Mb/1Gb/2Gb parts on Xilinx Zynq-7000 FPGA board.
Why not test the 256 Mb and 4 Gb parts as well? They might work 
perfectly well but adding support for untested hardware sounds wrong to 
me.

The datasheets you have linked do not specify a mapping between device 
ID and part number. So I can't verify that you are using the correct IDs 
here. But I'll trust you to get them right :-)

With the above comment addressed and 256 Mb and 4 Gb parts tested, 
please add
