94c32c9fd0 Mostly Build Improvements
- ROMSIZE is now a configuration variable instead of a command line parameter.
- Added CP/M license information based on new email from Bryan Sparks.

44b17ccc3a Improve Centronics Compatibility
- Renamed Centronics driver from "CEN" to "LPT" based on input that LPT is the more recognized name for IBM compatible Centronics interfaces.
- Modified LPT hardware detection to be more generic (no longer depends on MBC-specific hardware implementation).
- Fix to CPU speed display for SBC v2 (004 and above) speed selection mechanism.

a62f5805ca Add BOOT_DELAY Configuration Variable
Some systems use terminal devices (Raspberry Pi, etc.) that take a few seconds to be ready to display console text.  The BOOT_DELAY setting can be used to introduce an arbitrary delay (in seconds) in the boot process just prior to text output.  This can be used to avoid missing some of the boot messages.

bf965c2604 Minor Z280 Fixes
- Fixed the ROM VERIFY functionality on Z280.  It was indicating errors incorrectly.
- Revised the way that ZZRCC is built to remove a bunch of complexity that was causing issues.  An implication of this is that ZZRCC now treats the data loaded from the CF Card as a ROM disk instead of a RAM disk.
- Updated the assemblers to handle some more Z280 instructions used in HBIOS.
- When building ZZRCC, checks have been added to ensure the ROM image is exactly 256K.  The build defaults to 512K and that causes the ZZRCC disk image to be corrupted.  This will stop the build if the user fails to specify a 256K ROM size.

d5962681f1 UART Driver Update
- Some newer/multi-port UART chips now use MCR:3 to activate the interrupt pin(s), otherwise tri-state.  This update sets MCR:3 in all cases.
- Added UARTDUAL config variable that enables detection of a dual UART chip at 0x80 for MBC platform.
- Fixed a typo in TastyBasic Build script.

14b005d64e UART Driver Interrupt Driven Receive
- The UART driver has been enhanced to allow use of interrupt driven receive buffer and RTS flow control.  It will only be used if enabled and the chip detected has no auto-flow control capability.
