The previous mask (0xffffffe0)\nimplicitly truncated addresses to 32 bits.\n\nThis patch does not change the on-wire descriptor layout yet.\nIt only removes the internal 32-bit address limit and prepares\nfor later patches that will add full 64-bit QH/qTD/iTD/siTD support.\n\nUpdate the EHCI trace-events prototypes for QH, qTD, iTD, and siTD to\nuse uint64_t for the address argument and print it with PRIx64. This\nensures full 64-bit addresses are shown in trace output and improves\ndebugging of queue heads and transfer descriptors.\n\nMigration compatibility:\n\nTo preserve backward migration compatibility, keep the legacy 32-bit\nfetch address fields (a_fetch_addr_32, p_fetch_addr_32) alongside the\nnew 64-bit fields.\n\nMigration format is selected using a machine compat property\n\"x-migrate-fetch-addr-64bit\":\n\n- Old machine types migrate 32-bit fetch addresses\n- New machine types migrate full 64-bit fetch addresses\n\nThis is implemented using VMSTATE_UINT32_TEST() and\nVMSTATE_UINT64_TEST() so that only the appropriate format is migrated.\n\nIn pre_save, the 32-bit shadow fields are populated when migrating\nto old machine types. In post_load, the 32-bit values are restored\ninto the 64-bit fields when loading old migration streams.\n\nNo functional change.\n\nSigned-off-by: Jamin Lin <jamin_lin@aspeedtech.com>\n---\n
