support. Changes are rather simplifications of the SCRIPTS
interface (prior to complexifying it again;) ), dead code
removes and comment fixes.
Code removed:
- Handling of kernel variables referenced from SCRIPTS.
- Handling of selection without ATN.
Slightly rewritten:
- Handling of illegal phase (4/5) and data overrun conditions.
Simplifications:
- Extended error flag and bits now only set from the C code.
- Move the extended error status (xerr_status) and nego
status (nego_status) outside the data structure accessed
by SCRIPTS (struct dsb).
- Get rid of the script status field (scr_st).
- Only patch SCR_NO_OP SCRIPTS instructions to adapt SCRIPTS
to actual chip capabilities.
Cosmetic changes:
- Miscellaneous comments in SCRIPTS.
- FreeBSD_4_Bus define replaced by FreeBSD_Bus_Io_Abstraction.
