/*
 * ROM Vector information for calling drivers in ROMs
 *
 * According to information published on the Web by Apple, there have
 * been 9 different ROM families used in the Mac since the introduction
 * of the Lisa/XL through the latest PowerMacs (May 96).  Each family
 * has zero or more version variants and in some cases a version variant
 * may exist in one than one length format.  Generally any one specific
 * Mac will use a common set of routines within the ROM and a model-specific
 * set also in the ROM.  Luckily most of the routines used by NetBSD fall
 * into the common set and can therefore be defined in the ROM Family.
 * The offset addresses (address minus the ROM Base) of these common routines
 * is the same for all machines which use that ROM.  The offset addresses of
 * the machine-specific routines is generally different for each machine.
 * The machine-specific routines currently used by NetBSD/mac68k include:
 *       ADB_interrupt, PM_interrupt, ADBBase+130_interrupt,
 *       PMgrOp, jClkNoMem, Egret, InitEgret, and ADBReInit_JTBL
 *
 * It is possible that the routine at "jClkNoMem" is a common routine, but
 * some variation in addresses has been seen.  Also, execept for the very
 * earliest machines which used Egret, the machine-specific value of the
 * Egret routine may be unimportant as the machine-specific InitEgret code
 * seems to always set the OS Trap vector for Egret.
 *
 * Only three of the nine different ROMs are important to NetBSD/mac68k.
 * All other ROMs are used in early model Macs which are unable to run
 * NetBSD due to other hardware limitations such as 68000 CPU, no MMU
 * capability, or used only in PowerMacs.  The three that we are interested
 * in are:
 *
 * ROM Family $0178 - used in the II, IIx, IIcx, and SE/30
 *            All machines which use this ROM are now supported by NetBSD.
 *            There are no machine-dependent routines in these ROMs used by
 *            NetBSD/mac68k.  This ROM is always 256K in length.
 *
 * ROM Family $067c - used in Classic, Color Classic, Color Classic II,
 *                      IIci, IIsi, IIvi, IIvx, IIfx, LC, LC II, LC III,
 *                      LC III+, LC475, LC520, LC550, LC575, LC580, LC630,
 *                      MacTV, P200, P250, P275, P400/405/410/430, P450,
 *                      P460/466/467, P475/476, P520, P550/560, P575/577/578,
 *                      P580/588, P600, P630/631/635/636/637/638/640, Q605,
 *                      Q610, C610, Q630, C650, Q650, Q700, Q800, Q900, Q950,
 *                      PB140, PB145/145B, PB150, PB160, PB165, PB165c, PB170,
 *                      PB180, PB180c, Duo 210, Duo 230, Duo 250, Duo 270c,
 *                      Duo280, Duo 280c, PB 520/520c/540/540c/550
 *             This is the so-called "Universal" ROM used in almost all 68K
 *             machines. There are machine-dependent and machine-independent
 *             routines used by NetBSD/mac68k in this ROM, and except for the
 *             PowerBooks and the Duos, this ROM seems to be fairly well
 *             known by NetBSD/mac68k.  Desktop machines listed here that are
 *             not yet running NetBSD probably only lack the necessary
 *             addresses for the machine-dependent routines, or are waiting
 *             for IDE disk support.  This ROM is generally 1Meg in length,
 *             however when used in the IIci, IIfx, IIsi, LC, Classic II, and
 *             P400/405/410/430 it is 512K in length, and when used in the
 *             PB 520/520c/540/540c/550 it is 2Meg in length.
 *
 * ROM Family - $077d - used in C660AV/Q660AV, Q840AV
 *             The "Universal" ROM used on the PowerMacs and used in the
 *             68K line for the AV Macs only.  When used in the 68K AV
 *             machines the ROM is 2Meg in length; all uses in the PowerMac
 *             use a length of 4Meg.
