T1040QDS warm reboot

[Vineeth]

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.

then how's has-rstcr/reboot works ?
