I expected that
CFLAGS_OPTIMIZE_V += -ffunction-sections -fdata-sections
in BSP and linker -Wl,--gc-section could/sould resolve that.
So should I divide bspsmp.c into two files?
For example, bspsmp-startcpu.c, bspsmp-init.c.
What about
uint32_t _CPU_SMP_Initialize(void)
{
uint32_t cpu_count = (uint32_t)bsp_processor_count;
if ( cpu_count > 4 )
cpu_count = 4;
return cpu_count;
}
void _CPU_SMP_Finalize_initialization( uint32_t cpu_count )
{
/* Do nothing */
}
void _CPU_SMP_Prepare_start_multitasking( void )
{
/* Do nothing */
}
void _CPU_SMP_Send_interrupt( uint32_t target_cpu_index )
{
/* Generates IPI */
BCM2835_REG(BCM2836_MAILBOX_3_WRITE_SET_BASE +
0x10 * target_cpu_index) = 0x1;
}
should they go to the same compilation unit as _CPU_SMP_Start_processor
or bspsmp-init.c separate one.
Or I should not care about smpfatal08 or add required symbol to it.
It would be nice to get the smpfatal08 to work with this BSP. There is
already a special case for the the qoriq BSPs in this test, so maybe we
need something similar for the RPI.
