| 342 since it fires in normal situations | |

| 369 * src/hal_misc.c: | |
| 370 Disabled use of stand-alone ^C detection interrupt. This is now | |
| 371 done in the serial driver. Added cyg_hal_is_break() and | |
| 372 cyg_hal_user_break() to detect and provoke ^C processing. These | |
| 373 are used by the serial driver and will one day interact with the | |
| 374 BSP/Cygmon/GDB stubs to do the right thing. | |

| 403 1999-02-25 Nick Garnett <nickg@cygnus.co.uk> | |
| 404 | |
| 405 * src/vectors.S: | |
| 406 Changed label used to access scheduler lock to one that is not | |
| 407 mangled by C++. This is intended to make support for interrupt | |
| 408 handling in non-kernel configurations easier. | |
| 409 Added some code to initialize DRAM in ROM-only configurations. | |
| 410 | |
| 411 1999-02-23 Nick Garnett <nickg@cygnus.co.uk> | |
| 412 | |
| 413 * src/hal_misc.c: | |
| 414 Added support for SIGINT-causing magic breakpoint. This involves | |
| 415 passing a third, hidden argument to hal_ctrlc_isr() which is a | |
| 416 pointer to the saved CPU state. | |
| 417 | |
| 418 * src/vectors.S: | |
| 419 Added support for 66MHz part (untested). | |
| 420 Added support for SIGINT-causing magic breakpoint to allow | |
| 421 continuation after ^C. This also relies on CYGMON changes. | |
| 422 | |

| 489 RAM startup (CYG_HAL_STARTUP_RAM) so that minimal sim testing | |
| 490 works. Note: this is an instance where two definitions (of | |
