[Qemu-devel] [PATCH v3 03/27] ide: Reject ATA commands specific to drive kinds

[Markus Armbruster]

ACS-2 Table B.2 explicitly prohibits ATAPI devices from implementing
WIN_RECAL, WIN_READ_EXT, WIN_READDMA_EXT, WIN_READ_NATIVE_MAX,
WIN_MULTREAD_EXT, WIN_WRITE, WIN_WRITE_ONCE, WIN_WRITE_EXT,
WIN_WRITEDMA_EXT, WIN_MULTWRITE_EXT, WIN_WRITE_VERIFY, WIN_VERIFY,
WIN_VERIFY_ONCE, WIN_VERIFY_EXT, WIN_SPECIFY, WIN_MULTREAD,
WIN_MULTWRITE, WIN_SETMULT, WIN_READDMA, WIN_READDMA_ONCE,
WIN_WRITEDMA, WIN_WRITEDMA_ONCE, WIN_FLUSH_CACHE_EXT.  Restrict them
to IDE_HD and IDE_CFATA.

Same for CFA_WRITE_SECT_WO_ERASE, CFA_WRITE_MULTI_WO_ERASE.  Restrict
them to IDE_CFATA, like the other CFA_ commands.
