Stefan ? ;-)
Its the IP core from Cadence supporting SPI NOR flash and is present on the Altera SoCFPGA. Enabling access to such SPI NOR flash devices. QSPI stands for Quad-SPI and refers to the optional use of up to 4 data lines for flash access.
So perhaps something like this:
+config CADENCE_QSPI
- bool "Cadence QSPI driver"
- depends on DM_SPI
- help
Enable the Cadence QSPI driver. This driver can be used to +access the SPI NOR flash on platforms embedding this
Cadence IP core (like the Altera SoCFPGA). QSPI stands forQuad-SPI and refers to the optional use of up to 4 data linesfor flash access.
Please don't mention platforms in the help for what I think of as IP-block-vendor drivers. The Cadence QSPI block will be reused by others and I can see someone "needing" to patch the help text. How about: Enable the Cadence Quad-SPI (QSPI) driver. This driver can be used to access the SPI NOR flash on platforms embedding this Cadence IP core.
