 *
 * Revision 1.216  2006/11/08 08:49:39  marcucci
 * HAVE_UPDATE form CD and USB
 *
 * Revision 1.215  2006/11/06 16:41:13  chlapik

 *
 * Revision 1.214  2006/11/02 12:10:33  chlapik
 * - checked all global variables used by DMA CH0 interrupt and DEC or CTR task - disable/enable scheduling/interrupts used for protection
 * - functions AudioBufferResetPosition() and ResetAudioBuffer() check if DMA xfer is not active, only then do the modification of AB variables
 * - CDDA - repeat of last xfer:
 * 		- mark AB element used for repeat xfer as not empty in order that DEC doesn't reconfigure SRC, DMA, OIF
 * 		- after repeated xfer is finished, if new data available, start DMA xfer again, but set source address correctly, not one from previous xfer
 *
 * Revision 1.213  2006/10/31 14:14:18  chlapik
 * support for Layer I & II:

 *
 * Revision 1.212  2006/10/31 11:12:25  marcucci
 * Modified to make HAVE_UPDATE Working
 *
 * Revision 1.211  2006/10/27 13:16:11  chlapik
 * - fixed bug in com. with CAP - before sending new cmd, always clear responses - ready and PRE EOS
 * - when CTR is going to send ready to PLY and new cmd is already pending for CTR, don't send ready but only in special cases - logic modified
 * - multiply ready - if CTR forwards CAP error, then clear high 16 bits, where device and cmd is encoded
 * - waiting for read ready before sending new cmd to CAP - logic can be switched off with define
 * - preparation for read ready sent from CAP to CTR in subcode channel and not in read channel
 *
 * Revision 1.210  2006/10/23 14:02:03  chlapik
 * fixed bug - if dummy read (always one sector), then don't check if whole read xfer finished (only for normal reads)
 *
 * Revision 1.209  2006/10/23 09:02:31  marcucci

 * Minor change to remove compiler warning
 *
 * Revision 1.207  2006/10/20 08:47:32  chlapik
 * - fixed issues with pause and pause release cmds coming while play/search/pause_at cmds active - exception - don't cancel prebuffering cmd (play/search/pause_at)
 * - cmd INIT sent to CAP not from controller_cmd() (called by PLY) but from process_preevents() - otherwise it can happen that CAP executes INIT earlier than CTR activates FSM for checking READY from CAP
 * - fixed bugs in device handling macros - missing brackets for whole macro
 *
 * Revision 1.206  2006/10/18 09:52:09  chlapik
 * read toc and mount cmds contain also force_execution functionality
 *
 * Revision 1.205  2006/10/18 08:55:02  chlapik
 * fixed bug - prebuffering not working with error TWO_BUF_IN_PAR_ERROR
 *
 * Revision 1.204  2006/10/17 14:19:36  chlapik
 * - multiple ready
 * - modified devices handling: type of last cmd from PLY to CTR stored for each device separately
 * - CTR checks if there is not wrong unforced cmd for prebuffering while old one is still not finished
 * - new CTR - CAP interface:
 * 	- CTR is able to process info about amount of really provided data from CAP, re-ask for rest of data again
 * 	- number of xfered data calculates CTR itself (temporarily)
 * 	- sector lba in read requests for CDDA added
 * 	- CTR doesn't use ctr_read_cmd()
 * 	- CTR has posibility to work without ESP_HISTORY
 *
 * Revision 1.203  2006/10/17 09:45:32  trubac
 * toc reading and mounting improvement by BB
 *
 * Revision 1.202  2006/10/05 11:33:29  trubac
 * XAR_ReallocateTOC must be before CD_UpdateTracksInfo
 *
 * Revision 1.201  2006/09/26 10:19:19  belardi
 * Removed unused variable
 *
 * Revision 1.200  2006/09/19 11:03:57  chlapik
 * solved misunderstanding of Play_Mode and buffering_mode bits in cmd to CAP - buffering_mode is again present in cmd structure
 *
 * Revision 1.199  2006/09/18 13:22:27  chlapik
 * fixed bug - if FF cmd cancelled by FB
 * - wrong determination of search mode in process_preevents (not only data params but also play params must be checked)
 * - again checking errors for read requests from CAP
 *
 * Revision 1.198  2006/09/15 19:31:13  belardi
 * Merged the m8_cav2_cm80506_cs3563.
 * - name change printf-> dprintf
 * - name change X_LAST_ITEM
 * - changed xfer_prameters fields
 * - removed XAR_RelocateTOC
