Was wondering how "reboot" works from linux kernel for t1040qds.


When checked, @arch/powerpc/sysdev/fsl_soc.c 

__setup_rstcr, an ioremap is done for the offset 0xb0 and writes 0x2
to that to reboot the machine. and it works properly.


when checked the reference manual for T1040QDS, it was given that
RST_CTL is at offset 0x40 and the RST is the 7th bit of same. 

RSTCR is an SoC register (see DCFG_CCSR_RSTCR in T1040RM), not something
implemented by the board.  Are you perhaps looking at some QIXIS
register?
