ide: doc: remove compilation options section from ide-cd documentation 



This section pointed out to compilation options which no longer exist.

VERBOSE_IDE_CD_ERRORS has been replace by config option
CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS.

STANDARD_ATAPI is no longer needed, since the non-standard drivers, which
required bcd2bin are now detected, and there's a flag for them.

NO_DOOR_LOCKING is now a sysctl parameter for cdrom drivers.

CDROM_NBLOCKS_BUFFER is not used anymore. The READAUDIO is now in cdrom.c and it
allocates as much as user space has requested to read, backing off if it fails.

TEST is not there anymore or in cdrom either. ide allows to send ATA commands
through ioctl, although it may be helpful to send MMC packets through the cdrom
layer directly.

4. Compilation options

----------------------



There are a few additional options which can be set when compiling the

driver.  Most people should not need to mess with any of these; they

are listed here simply for completeness.  A compilation option can be

enabled by adding a line of the form `#define <option> 1' to the top

of ide-cd.c.  All these options are disabled by default.



VERBOSE_IDE_CD_ERRORS

  If this is set, ATAPI error codes will be translated into textual

  descriptions.  In addition, a dump is made of the command which

  provoked the error.  This is off by default to save the memory used

  by the (somewhat long) table of error descriptions.  



STANDARD_ATAPI

  If this is set, the code needed to deal with certain drives which do

  not properly implement the ATAPI spec will be disabled.  If you know

  your drive implements ATAPI properly, you can turn this on to get a

  slightly smaller kernel.



NO_DOOR_LOCKING

  If this is set, the driver will never attempt to lock the door of

  the drive.



CDROM_NBLOCKS_BUFFER

  This sets the size of the buffer to be used for a CDROMREADAUDIO

  ioctl.  The default is 8.



TEST

  This currently enables an additional ioctl which enables a user-mode

  program to execute an arbitrary packet command.  See the source for

  details.  This should be left off unless you know what you're doing.
