From c8d91839ff0af2f6cf8bbeeecc6e8f7bbf1315c9 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Fri, 2 Jul 1999 18:57:11 +0000 Subject: Patch from Ralf Corsepius that splits boot_card() and main() into separate files to ease configuration of other packages. This was a big step in the way to build TCL, ncurses, and zlib for RTEMS. --- c/src/lib/libbsp/shared/bootcard.c | 96 ++++++++++++++++++++++++++++++++++++++ c/src/lib/libbsp/shared/main.c | 85 --------------------------------- 2 files changed, 96 insertions(+), 85 deletions(-) create mode 100644 c/src/lib/libbsp/shared/bootcard.c (limited to 'c/src/lib/libbsp/shared') diff --git a/c/src/lib/libbsp/shared/bootcard.c b/c/src/lib/libbsp/shared/bootcard.c new file mode 100644 index 0000000000..9f7a3893ce --- /dev/null +++ b/c/src/lib/libbsp/shared/bootcard.c @@ -0,0 +1,96 @@ +/* + * A simple main which can be used on any embedded target. + * + * This style of initialization insures that the C++ global + * constructors are executed after RTEMS is initialized. + * + * Thanks to Chris Johns for this idea. + * + * COPYRIGHT (c) 1989-1998. + * On-Line Applications Research Corporation (OAR). + * Copyright assigned to U.S. Government, 1994. + * + * The license and distribution terms for this file may be + * found in the file LICENSE in this distribution or at + * http://www.OARcorp.com/rtems/license.html. + * + * $Id$ + */ + +#include + +extern void bsp_start( void ); +extern void bsp_cleanup( void ); + +extern rtems_configuration_table Configuration; +extern rtems_configuration_table BSP_Configuration; +extern rtems_cpu_table Cpu_table; + +rtems_interrupt_level bsp_isr_level; + +/* + * Since there is a forward reference + */ + +int main(int argc, char **argv); + +int boot_card(int argc, char **argv) +{ + int status; + + /* + * Set default values for the CPU Table fields all ports must have. + * These values can be overridden in bsp_start() but they are + * right most of the time. + */ + + Cpu_table.pretasking_hook = NULL; + Cpu_table.predriver_hook = NULL; + Cpu_table.postdriver_hook = NULL; + Cpu_table.idle_task = NULL; + Cpu_table.do_zero_of_workspace = TRUE; + Cpu_table.interrupt_stack_size = RTEMS_MINIMUM_STACK_SIZE; + Cpu_table.extra_mpci_receive_server_stack = 0; + Cpu_table.stack_allocate_hook = NULL; + Cpu_table.stack_free_hook = NULL; + + + /* + * Copy the configuration table so we and the BSP wants to change it. + */ + + BSP_Configuration = Configuration; + + /* + * The atexit hook will be before the static destructor list's entry + * point. + */ + + bsp_start(); + + /* + * Initialize RTEMS but do NOT start multitasking. + */ + + bsp_isr_level = + rtems_initialize_executive_early( &BSP_Configuration, &Cpu_table ); + + /* + * Call main() and get the global constructors invoked if there + * are any. + */ + + status = main(argc, argv); + + /* + * Perform any BSP specific shutdown actions. + */ + + bsp_cleanup(); + + /* + * Now return to the start code. + */ + + return status; +} diff --git a/c/src/lib/libbsp/shared/main.c b/c/src/lib/libbsp/shared/main.c index d516ff9b08..2ac7a0a4af 100644 --- a/c/src/lib/libbsp/shared/main.c +++ b/c/src/lib/libbsp/shared/main.c @@ -21,95 +21,10 @@ char *rtems_progname; -extern void bsp_start( void ); -extern void bsp_cleanup( void ); - -extern rtems_configuration_table Configuration; -extern rtems_configuration_table BSP_Configuration; -extern rtems_cpu_table Cpu_table; - -#if defined(USE_INIT_FINI) -extern void _fini( void ); -extern void _init( void ); -#endif - rtems_interrupt_level bsp_isr_level; -/* - * Since there is a forward reference - */ - -int main(int argc, char **argv); - -int boot_card(int argc, char **argv) -{ - int status; - - /* - * Set default values for the CPU Table fields all ports must have. - * These values can be overridden in bsp_start() but they are - * right most of the time. - */ - - Cpu_table.pretasking_hook = NULL; - Cpu_table.predriver_hook = NULL; - Cpu_table.postdriver_hook = NULL; - Cpu_table.idle_task = NULL; - Cpu_table.do_zero_of_workspace = TRUE; - Cpu_table.interrupt_stack_size = RTEMS_MINIMUM_STACK_SIZE; - Cpu_table.extra_mpci_receive_server_stack = 0; - Cpu_table.stack_allocate_hook = NULL; - Cpu_table.stack_free_hook = NULL; - - - /* - * Copy the configuration table so we and the BSP wants to change it. - */ - - BSP_Configuration = Configuration; - - /* - * The atexit hook will be before the static destructor list's entry - * point. - */ - - bsp_start(); - - /* - * Initialize RTEMS but do NOT start multitasking. - */ - - bsp_isr_level = - rtems_initialize_executive_early( &BSP_Configuration, &Cpu_table ); - - /* - * Call main() and get the global constructors invoked if there - * are any. - */ - -#if defined(USE_INIT_FINI) - atexit( _fini ); - _init(); -#endif - - status = main(argc, argv); - - /* - * Perform any BSP specific shutdown actions. - */ - - bsp_cleanup(); - - /* - * Now return to the start code. - */ - - return status; -} - int main(int argc, char **argv) { - if ((argc > 0) && argv && argv[0]) rtems_progname = argv[0]; else -- cgit v1.2.3
