[PATCH v1 0/2] spi: cadence: Add xSPI controller driver support

[Boon Khai Ng]

This patch series introduces initial support for the Cadence xSPI
controller in U-Boot.

Patch 1 ports the Cadence xSPI driver from the Linux kernel. The controller
supports three operating modes (ACMD, STIG, and Direct), with only the STIG
mode currently enabled in this driver. The driver has been functionally
verified on the Intel Simics platform and is intended for evaluation and
experimental use at this stage.

Patch 2 adds the corresponding Kconfig and Makefile entries to enable
building the driver.
