2024-07-09	misc: keba: Fix missing AUXILIARY_BUS dependency	Gerhard Engleder
	The cp500 driver creates auxiliary devices. Kernel configs without CONFIG_AUXILIARY_BUS lead to warnings like this: cp500.c: undefined reference to `auxiliary_device_init' cp500.c: undefined reference to `__auxiliary_device_add' Add missing dependency to AUXILIARY_BUS to KEBA_CP500 Kconfig.

2024-07-04	misc: keba: Add basic KEBA CP500 system FPGA support	Gerhard Engleder
	The KEBA CP500 system FPGA is a PCIe device, which consists of multiple IP cores. Every IP core has its own auxiliary driver. The cp500 driver registers an auxiliary device for each device and the corresponding drivers are loaded by the Linux driver infrastructure. Currently 3 variants of this device exists. Every variant has its own PCI device ID, which is used to determine the list of available IP cores. In this first version only the auxiliary device for the I2C controller is registered. Besides the auxiliary device registration some other basic functions of the FPGA are implemented; e.g, FPGA version sysfs file, keep FPGA configuration on reset sysfs file, error message for errors on the internal AXI bus of the FPGA.
