- * Macros for feature tests, used to enable include file features
- * for chip features only present in certain chip revisions.
- *
- * SIBYTE_HDR_FEATURES may be defined to be the mask value chip/revision
- * which is to be exposed by the headers. If undefined, it defaults to
- * "all features."
- *
- * Use like:
- *
- * #define SIBYTE_HDR_FEATURES SIBYTE_HDR_FMASK_112x_PASS1
- *
- * Generate defines only for that revision of chip.
- *
- * #if SIBYTE_HDR_FEATURE(chip,pass)
- *
- * True if header features for that revision or later of
- * that particular chip type are enabled in SIBYTE_HDR_FEATURES.
- * (Use this to bracket #defines for features present in a given
- * revision and later.)
- *
- * Note that there is no implied ordering between chip types.
- *
- * Note also that 'chip' and 'pass' must textually exactly
- * match the defines below. So, for example,
- * SIBYTE_HDR_FEATURE(112x, PASS1) is OK, but
- * SIBYTE_HDR_FEATURE(1120, pass1) is not (for two reasons).
- *
- * #if SIBYTE_HDR_FEATURE_UP_TO(chip,pass)
- *
- * Same as SIBYTE_HDR_FEATURE, but true for the named revision
- * and earlier revisions of the named chip type.
- *
- * #if SIBYTE_HDR_FEATURE_EXACT(chip,pass)
- *
- * Same as SIBYTE_HDR_FEATURE, but only true for the named
- * revision of the named chip type. (Note that this CANNOT
- * be used to verify that you're compiling only for that
- * particular chip/revision. It will be true any time this
- * chip/revision is included in SIBYTE_HDR_FEATURES.)
- *
- * #if SIBYTE_HDR_FEATURE_CHIP(chip)
- *
- * True if header features for (any revision of) that chip type
- * are enabled in SIBYTE_HDR_FEATURES. (Use this to bracket
- * #defines for features specific to a given chip type.)
- *
- * Mask values currently include room for additional revisions of each
- * chip type, but can be renumbered at will. Note that they MUST fit
- * into 31 bits and may not include C type constructs, for safe use in
- * CPP conditionals. Bit positions within chip types DO indicate
- * ordering, so be careful when adding support for new minor revs.

- * Naming schemes for constants in these files:
- *
- * M_xxx MASK constant (identifies bits in a register).
- * For multi-bit fields, all bits in the field will
- * be set.
- *
- * K_xxx "Code" constant (value for data in a multi-bit
- * field). The value is right justified.
- *
- * V_xxx "Value" constant. This is the same as the
- * corresponding "K_xxx" constant, except it is
- * shifted to the correct position in the register.
- *
- * S_xxx SHIFT constant. This is the number of bits that
- * a field value (code) needs to be shifted
- * (towards the left) to put the value in the right
- * position for the register.
- *
- * A_xxx ADDRESS constant. This will be a physical
- * address. Use the PHYS_TO_K1 macro to generate
- * a K1SEG address.
- *
- * R_xxx RELATIVE offset constant. This is an offset from
- * an A_xxx constant (usually the first register in
- * a group).
- *
- * G_xxx(X) GET value. This macro obtains a multi-bit field
- * from a register, masks it, and shifts it to
- * the bottom of the register (retrieving a K_xxx
- * value, for example).
- *
- * V_xxx(X) VALUE. This macro computes the value of a
- * K_xxx constant shifted to the correct position
- * in the register.
