[PATCH v8 0/3] mtd: spi-nor: Add support for Infineon s25hl-t/s25hs-t

[tkuw584924 at gmail.com]

From: Takahiro Kuwano <Takahiro.Kuwano at infineon.com>

The S25HL-T/S25HS-T family is the Infineon SEMPER Flash with Quad SPI.

The datasheets can be found in the following link.
https://www.infineon.com/dgdl/Infineon-S25HS256T_S25HS512T_S25HS01GT_S25HL256T_S25HL512T_S25HL01GT_256-Mb_(32-MB)_512-Mb_(64-MB)_1-Gb_(128-MB)_HS-T_(1.8-V)_HL-T_(3.0-V)_Semper_Flash_with_Quad_SPI-DataSheet-v02_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ee674b86ee3&da=t

The series depends on:
https://lore.kernel.org/all/20220210023334.408926-4-tudor.ambarus@microchip.com/T/

Tested on Xilinx Zynq-7000 FPGA board.
