Best regards, Krzysztof
From: Nick Hawkins <nick.hawkins@hpe.com> Changes since v3: *Fixed indentations in hpe,gxp-spifi.yaml Changes since v2: *Changed the CONFIG_SPI_GXP from y to m in defconfig *Removed extra space around < > for reg in hpe,gxp-spifi.yaml *Changed interrupt-parrent to interrupt-parent in hpe,gxp-spifi.yaml *Removed repeated include file in spi-gxp.c *Removed unnecessary initialization of ret variable in spi-gxp.c *Removed conditional variable checks where failure is not possible in spi-gxp.c *Removed unecessary variable cs in spi-gxp.c *Removed blank gxp-spifi-remove function in spi-gxp.c *Fixed error messages so they are not repetitive The GXP supports 3 separate SPI interfaces to accommodate the system flash, core flash, and other functions. The SPI engine supports variable clock frequency, selectable 3-byte or 4-byte addressing and a configurable x1, x2, and x4 command/address/data modes. The memory buffer for reading and writing ranges between 256 bytes and 8KB. This driver supports access to the core flash and bios part.
