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. ********************************************************************* / #define SIBYTE_HDR_FMASK_1250_ALL 0x000000ff #define SIBYTE_HDR_FMASK_1250_PASS1 0x00000001 #define SIBYTE_HDR_FMASK_1250_PASS2 0x00000002 #define SIBYTE_HDR_FMASK_1250_PASS3 0x00000004 #define SIBYTE_HDR_FMASK_112x_ALL 0x00000f00 #define SIBYTE_HDR_FMASK_112x_PASS1 0x00000100 #define SIBYTE_HDR_FMASK_1480_ALL 0x0000f000 #define SIBYTE_HDR_FMASK_1480_PASS1 0x00001000 #define SIBYTE_HDR_FMASK_1480_PASS2 0x00002000 / Bit mask for chip/revision.

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. ********************************************************************* / / * Cast to 64-bit number.
