Refactor CDROM host support
- Completely separate GDROM hardware (in gdrom/gdrom.c) from generic CDROM
support (now in drivers/cdrom)
- Add concept of 'sector sources' that can be mixed and matched to create
cdrom discs (makes support of arbitrary disc types much simpler)

However, the cdrtools developers are no longer10.6 +involved in the development of this spinoff and therefore shall not10.7 +be made responsible for any problem caused by it. Do not try to get10.8 +support for this program by contacting the original authors.10.9 +10.10 +This is a small description for the Reed-Solomon library intended for10.11 +CD sector formatting.10.12 +10.13 +Basics:10.14 +It is assumed that you have a basic knowledge of cd sector formats.10.15 +10.16 +The library can handle three types of sector data:10.17 + data sectors,10.18 + audio sectors, and10.19 + sub channel r-w sectors10.20 +10.21 +Currently only encoding is implemented. Decoding and optionally10.22 +error correction is planned for later.10.23 +10.24 +Stages:10.25 +10.26 +The process of sector formatting has several stages. Beginning with10.27 +a data sector (2048, 2324, or 2336 bytes) a sector of 2352 bytes is10.28 +built. This format can be read raw by SCSI MMC-2 and ATAPI drives and10.29 +is accepted by cd burners. The additions are an optionally 32 bit CRC10.30 +checksum and two layers of Reed-Solomon codes (called Reed-Solomon10.31 +Product Code RSPC).10.32 +This sector is then scrambled (exor'ed with a bitstream).10.33 +The result is called F1 frames. Afterwards even and odd bytes are10.34 +swapped, this is called F2 frames. The result is equivalent to an10.35 +audio sector and is treated as such by the cd burner.10.36 +So, if we wrote a series of sectors (F2 frames) into a CDR file and10.37 +later burned them as 'audio', they would turn up as perfect data sectors.10.38 +10.39 +So, now we are at the level of audio sectors. Audio sectors get their10.40 +own error correction data (called CIRC). Sector size goes up to10.41 +3136 bytes (that is 4/3 times 2352 bytes). Furthermore different10.42 +words get delayed differently and swap positions. The result is ready10.43 +to be fed into the so-called EightFourteenModulator (when subchannels10.44 +have been added).10.45 +10.46 +Now, only sub channels are missing. While the p and q sub10.47 +channels have to be generated elsewhere, any supplied r-w subchannel10.48 +user data is protected by two levels of error correction10.49 +codes. This format is read by cd burners when burning cd+graphics.10.50 +The cdimage is a sequence of sectors, each containing audio data and10.51 +after that subchannel data.10.52 +Similar to audio sectors delaying and permutation of words10.53 +takes place. After that the cd burner would mix sub channel data with10.54 +the formatted audio sectors to feed the EFModulator.10.55 +10.56 +NOTE: Most of the described stages need not to be done in order to10.57 +prepare sectors for burning, since all cd burners do at least CIRC,10.58 +delaying and swaps. For data sectors they also do scrambling and f210.59 +frame generation.10.60 +10.61 +Encoding routines:10.62 +10.63 +For data sectors10.64 + int do_encode_L2(unsigned char *inout, int sectortype, unsigned address);10.65 +10.66 + encodes data sectors. The returned data is __unscrambled__ and not in10.67 + F2-frame format.10.68 +10.69 +Parameters are:10.70 + inout pointer to an array of at least 2352 bytes.10.71 + sectortype One of the MODE_* constants from ecc.h. This defines10.72 + how to format the sector.10.73 + address The logical address to be used in the header10.74 + (150 = 0:2.0 MSF).10.75 +10.76 +NOTE: the data portion has be to aligned properly for performance10.77 +reasons (see ecc.h for details). So, no moves are necessary here.10.78 +10.79 +Generating f2 frames to be used like audio sectors10.80 + int scramble_L2(unsigned char *inout)10.81 +10.82 + generates f2 frames in place from sectors generated by do_encode_L2().10.83 +10.84 +Parameters are:10.85 + inout pointer to an array of at least 2352 bytes.10.86 +10.87 +10.88 +10.89 +For sub channels10.90 + int do_encode_sub(unsigned char in[LSUB_RAW*PACKETS_PER_SUBCHANNELFRAME],10.91 + unsigned char out[(LSUB_RAW+LSUB_Q+LSUB_P)*10.92 + PACKETS_PER_SUBCHANNELFRAME],10.93 + int delay1, int permute);10.94 +10.95 + repack user data and add error correction data. P and q subchannels10.96 +should be added later, since all bytes are in place then.10.97 +10.98 +Parameters are:10.99 + in pointer to an array of at least 72 bytes. It contains10.100 + the user data for one frame.10.101 + out pointer to an array of at least 96 bytes. Here is10.102 + output frame is placed.10.103 + delay1 do low level delaying, when set to 1.10.104 + permute do low level permutations, when set to 1.10.105 +10.106 +NOTE: Probably both options need either to be set on (1) or off (0) together.10.107 +10.108 +There is more, but that is seldomly used.10.109 +10.110 +Tests:10.111 +The library is accompanied by small verify programs, that compare real10.112 +raw sectors with the formatted results. They are also intended as demo10.113 +applications (how to use the library). In order to be able to feed10.114 +real raw sectors into them, the package read2448 is recommended/needed.10.115 +You can only verify sector streams of one sector type, currently no mix.10.116 +10.117 +For more information have a look into ecc.h10.118 +10.119 +recommended Documents:10.120 +Yellow Book or ISO 1014910.121 +Appendix Red Book10.122 +Red Book or IEC 90810.123 +10.124 +Source: libedc/README from cdrtools package10.125 +Edited for cdrkit by Christian Fromme <kaner@strace.org>10.126 +
