Potential Fatal Error in BSP efi68k efi332 mrm332 in 4.6.0-pre4

[Cedric Aubert]

Hi,

In all this BSP (68k) we use a function called
Spurious_Initialize to init the exception vector to
a spurious it handler. To do this we use
set_vector(...,..., 1), this use a generic RTMES
handler.
And set_vector(...,..., 1) use the _ISR_Vector_Table.
But in those BSP, Spurious_Initialize is call in the 
first start fucntion (start.c or .S) before the call
of
boot_card fucntion. But boot_card call
rtems_initialize_executive_early that's call 
_ISR_Handler_Initialization witch allocate the
_ISR_Vector_table in the Workspace. So the function
Spurious_Initialize was call and modified the
_ISR_Vector_table before the _ISR_Vector_Table
initialization. The correct thing to do is to
call Spurious_initialize fucntion in the 
predriver_hook like in the sim68000 BSP.
I have seen this problem during porting my
custom 68k board, and test it that's correctly work.

Hope that help.

Cedric
