[U-Boot] [PATCH 0/4] Add support for Cadence QSPI on K2G

[Vignesh R]

This series adds support for Cadence QSPI controller present on K2G SoC.

The first patch extends AHB address to 32 bit as K2G has 32 bit AHB
address. Second patch enable QUAD mode based on DT data instead of
relying on config option. And last to patches add DT node and add
configs to enable the driver.

Depends on [1] to enable SPI driver model support on K2G and [2] to
support different bus frequencies for two different SPI controllers
present on K2G EVM.
