2025-09-15cdx: Export Symbols for MCDI RPC and InitializationShubhrajyoti Datta1-0/+7
The cdx_mcdi_init(), cdx_mcdi_process_cmd(), and cdx_mcdi_rpc() functions are needed by the VersalNET EDAC module that interact with the MCDI (Management Controller Direct Interface) framework. These functions facilitate communication between different hardware components by enabling command execution and status management.

2025-09-15cdx: Split mcdi.h and reorganize headersShubhrajyoti Datta1-0/+192
Move bitfield.h from the CDX controller directory to include/linux/cdx to make them accessible to other drivers. As part of this refactoring, split mcdi.h into two headers: - mcdi.h: retains interface-level declarations - mcdid.h: contains internal definitions and macros This is in preparation for VersalNET EDAC driver that relies on it.
