[6.6] HYGON: Add new pci device id and modify psp_do_cmd() interface

[chench246]

1. add new psp/ccp device id and modify psp_do_cmd() interface to not rely on sev device.

Reference: https://gitee.com/openeuler/kernel/pulls/16281

2. bugfix: Fix for potential memory Out-of-Bounds access due to insufficient array size in TDM driver.

Summary by Sourcery

Add new Hygon PCI device IDs, decouple PSP command execution from SEV, and correct TDM driver buffer sizing to avoid memory overflows.

New Features:

• Add support for two new Hygon PCI device IDs (0x14d8 and 0x14c6)

Bug Fixes:

• Fix potential out-of-bounds access in the TDM driver by using KSYM_NAME_LEN for the symbol buffer size

Enhancements:

• Refactor PSP command interface to remove dependency on the SEV device by introducing an internal wait queue and psp_wait_cmd_ioc function

Reviewer's Guide

This PR decouples PSP command execution from the SEV device by introducing a dedicated wait queue and command-wait helper, updates the IRQ handler and header accordingly, adds two new Hygon PCI device IDs, and fixes an out-of-bounds buffer in the TDM driver.

File-Level Changes

Change	Details	Files
Refactor PSP command interface off SEV and implement dedicated wait mechanism	Define static psp_int_rcvd flag and psp_int_queue wait queue Add psp_wait_cmd_ioc() to wait on psp_int_queue instead of sev_wait_cmd_ioc Update __psp_do_cmd_locked to use psp->io_regs, psp_int_rcvd, psp_cmd_timeout, and invoke psp_wait_cmd_ioc Initialize psp_int_queue in psp_dev_init when vendor is Hygon Declare extern psp_int_queue in hygon/psp-dev.h	drivers/crypto/ccp/hygon/psp-dev.c drivers/crypto/ccp/psp-dev.c drivers/crypto/ccp/hygon/psp-dev.h
Extend IRQ handler to signal new PSP wait queue	Modify psp_irq_handler_hygon to set psp_int_rcvd and wake psp_int_queue Retain backward compatibility by waking sev->int_queue when sev is non-NULL	drivers/crypto/ccp/hygon/psp-dev.c
Add new Hygon PCI device IDs	Introduce PCI_VDEVICE entries for IDs 0x14d8 and 0x14c6	drivers/crypto/ccp/sp-pci.c
Fix potential out-of-bounds in TDM driver	Replace fixed 128-byte symbol_buf with KSYM_NAME_LEN to ensure sufficient buffer size	drivers/crypto/ccp/hygon/tdm-dev.c

Hi @chench246. Thanks for your PR.

I'm waiting for a deepin-community member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
