using obj-y for targetprogs only works until only a single program
is compiled. Adding the second one will end up in the linker trying
to link both together.
Add targetprogs-y to fix this.

When globalvar_add_simple was called on previously existing variables
then the value was overwritten, even when value was passed as NULL.
Do not overwrite the value in this case which allows us to do a 'global'
on the same variable multiple times without loosing the values.

Some of the irq can still be on after a reset or power on as the IP are
powered by the backup power. This could lead to an interrupt dead lock
when the kernel boot. So disable them before booting.

since the switch to common clock, ethernet driver doesn't works and
and access to the network leads to :
eth0: Read MDIO failed...
unable to handle NULL pointer dereference at address 0x000000c7
The problem is that bit 31 (SLEEP) of register HW_CLKCTRL_ENET is kept
to its default value (1) which means : "put Ethernet block in sleep mode.
CLK_H_MAC0(1), CLK_H_MAC0(1)_S, and CLK_ENET0(1)_TX are gated off.
Ethernet can be wakeup remotely in sleep mode"
In that case the FEC don't get its clock.
This patch fix the problem by toggling this bit when FEC's clock is
enabled.
Tested on i.MX28EVK.

since the switch to common clock, SPI driver reports :
MXS: Timeout resetting block via register 0x80014000
mxs_spi mxs_spi2: MXS SPI: Timeout waiting for start
The reason is that the clock is not enabled anywhere in
the driver.

For the MPC85xx family of SOCs Linux expects any boot firmware
information to be passed in the first 64MiB of memory. This adds support
to ensure that the device tree is relocated to a valid location if it is
outside that address range.
For the other SOC family currently present in the ppc architecture, the
default is not to relocate as at Linux startup the virtual address
equals the physical address.

This adds support for populating derived properties of the mpc85xx SOC
which are not typically included in the dtb directly.
This update is based on U-Boot code from common/fdt_support.c
and arch/powerpc/cpu/mpc85xx/fdt.c - version git-2b26201.

Convert to static inline functions and use lower case letters for function
names. Also, include mach/debug_ll.h when an architecture provides support
for debug_ll, not only when it's actually enabled. This allows architecures
to put some UART initialization code into mach/debug_ll.h which is compiled
out when debug_ll is disabled.
