* 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
|
||
|
|

|
|
* 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.
