Use const in PROGRAMMER function arguments where appropriate In order to get meaningful const properties for the PROGRAMMER, AVRPART and AVRMEM arguments, some code needed to be moved around, otherwise a network of "tainted" assignments risked rendering nothing const: - Change void (*enable)(PROGRAMMER *pgm) to void (*enable)(PROGRAMMER *pgm, const AVRPART *p); this allows changes in the PROGRAMMER structure after the part is known. For example, use TPI, UPDI, PDI functions in that programmer appropriate to the part. This used to be done later in the process, eg, in the initialize() function, which "taints" all other programmer functions wrt const and sometimes requires other finessing with flags etc. Much clearer with the modified enable() interface. - Move TPI initpgm-type code from initialize() to enable() --- note that initpgm() does not have the info at the time when it is called whether or not TPI is required - buspirate.c: move pgm->flag to PDATA(pgm)->flag (so legitimate modification of the flag does not change PROGRAMMER structure) - Move AVRPART_INIT_SMC and AVRPART_WRITE bits from the flags field in AVRPART to jtagmkII.c's private data flags32 fiels as FLAGS32_INIT_SMC and FLAGS32_WRITE bits - Move the xbeeResetPin component to private data in stk500.c as this is needed by xbee when it saddles on the stk500 code (previously, the flags component of the part was re-dedicated to this) - Change the way the "chained" private data are used in jtag3.c whilst keeping the PROGRAMMER structure read-only otherwise - In stk500v2.c move the STK600 pgm update from stk500v2_initialize() to stk500v2_enable() so the former keeps the PROGRAMMER structure read-only (for const assertion). - In usbasp change the code from changing PROGRAMMER functions late to dispatching to TPI or regular SPI protocol functions at runtime; reason being the decision whether to use TPI protocol is done at run-time depending on the capability of the attached programmer Also fixes Issue #1071, the treatment of default eecr value.

Use const in PROGRAMMER function arguments where appropriate In order to get meaningful const properties for the PROGRAMMER, AVRPART and AVRMEM arguments, some code needed to be moved around, otherwise a network of "tainted" assignments risked rendering nothing const: - Change void (*enable)(PROGRAMMER *pgm) to void (*enable)(PROGRAMMER *pgm, const AVRPART *p); this allows changes in the PROGRAMMER structure after the part is known. For example, use TPI, UPDI, PDI functions in that programmer appropriate to the part. This used to be done later in the process, eg, in the initialize() function, which "taints" all other programmer functions wrt const and sometimes requires other finessing with flags etc. Much clearer with the modified enable() interface. - Move TPI initpgm-type code from initialize() to enable() --- note that initpgm() does not have the info at the time when it is called whether or not TPI is required - buspirate.c: move pgm->flag to PDATA(pgm)->flag (so legitimate modification of the flag does not change PROGRAMMER structure) - Move AVRPART_INIT_SMC and AVRPART_WRITE bits from the flags field in AVRPART to jtagmkII.c's private data flags32 fiels as FLAGS32_INIT_SMC and FLAGS32_WRITE bits - Move the xbeeResetPin component to private data in stk500.c as this is needed by xbee when it saddles on the stk500 code (previously, the flags component of the part was re-dedicated to this) - Change the way the "chained" private data are used in jtag3.c whilst keeping the PROGRAMMER structure read-only otherwise - In stk500v2.c move the STK600 pgm update from stk500v2_initialize() to stk500v2_enable() so the former keeps the PROGRAMMER structure read-only (for const assertion). - In usbasp change the code from changing PROGRAMMER functions late to dispatching to TPI or regular SPI protocol functions at runtime; reason being the decision whether to use TPI protocol is done at run-time depending on the capability of the attached programmer Also fixes Issue #1071, the treatment of default eecr value.
