These collectively + are referred to as work area. If the BSP supports this, then it does + not have to include code to split the available memory between the + two areas. This reduces the amount of code in the BSP specific + bspstart.c file. Additionally, the shared framework can initialize + the C Library, call rtems_debug_enable(), and dirty the work area + memory. Until most/all BSPs support this new capability, if the BSP + supports this, it should call + RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac. When + the transition is complete, this autoconf macro can be removed. + 2008-05-15 Thomas Doerfler <Thomas.Doerfler@embedded-brains.de> * irq/irq.c: diff --git a/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c b/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c index 72a2ac8ad2..a0b9aaa84c 100644 --- a/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c +++ b/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c @@ -94,14 +94,10 @@ void bsp_pretasking_hook(void) * the kernel and the application can be linked and burned into ROM * independently of each other. */ - extern unsigned char _HeapStart; - extern unsigned char _HeapEnd; + extern unsigned char _HeapStart; + extern unsigned char _HeapEnd; - bsp_libc_init( &_HeapStart, &_HeapEnd - &_HeapStart, 0 ); - -#ifdef RTEMS_DEBUG - rtems_debug_enable( RTEMS_DEBUG_ALL_MASK ); -#endif + bsp_libc_init( &_HeapStart, &_HeapEnd - &_HeapStart, 0 ); } /* diff --git a/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c.nocache b/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c.nocache index 1776fa219f..a943e9e4d0 100644 --- a/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c.nocache +++ b/c/src/lib/libbsp/powerpc/mbx8xx/startup/bspstart.c.nocache @@ -71,14 +71,10 @@ void bsp_pretasking_hook(void) * the kernel and the application can be linked and burned into ROM * independently of each other. */ - extern unsigned char _HeapStart; - extern unsigned char _HeapEnd; + extern unsigned char _HeapStart; + extern unsigned char _HeapEnd; - bsp_libc_init( &_HeapStart, &_HeapEnd - &_HeapStart, 0 ); - -#ifdef RTEMS_DEBUG - rtems_debug_enable( RTEMS_DEBUG_ALL_MASK ); -#endif + bsp_libc_init( &_HeapStart, &_HeapEnd - &_HeapStart, 0 ); } |
