Previously, the address of a requested capability is define like that
"#define PCI_DCR 0x78"
But, the addresses of capabilities is different with regard to PCIe revs.
So this method is not flexible.
Now a function to get the address of a requested capability is added and used.
It can get the address dynamically by capability ID.
The step of this function:
1. Read Status register in PCIe configuration space to confirm that
Capabilities List is valid.
2. Find the address of Capabilities Pointer Register.
3. Find the address of requested capability from the first capability.

Clock requirement for qspi clk is 192 Mhz.
According to the below formulae,
f dpll = f ref * 2 * m /(n + 1)
clockoutx2_Hmn = f dpll / (hmn+ 1)
fref = 20 Mhz, m = 96, n = 4 gives f dpll = 768 Mhz
For clockoutx2_Hmn to be 768, hmn + 1 should be 4.

For the KVM and XEN hypervisors to be usable, we need to enter the
kernel in HYP mode. Now that we already are in non-secure state,
HYP mode switching is within short reach.
While doing the non-secure switch, we have to enable the HVC
instruction and setup the HYP mode HVBAR (while still secure).
The actual switch is done by dropping back from a HYP mode handler
without actually leaving HYP mode, so we introduce a new handler
routine in our new secure exception vector table.
In the assembly switching routine we save and restore the banked LR
and SP registers around the hypercall to do the actual HYP mode
switch.
The C routine first checks whether we are in HYP mode already and
also whether the virtualization extensions are available. It also
checks whether the HYP mode switch was finally successful.
The bootm command part only calls the new function after the
non-secure switch.

Currently the non-secure switch is only done for the boot processor.
To enable full SMP support, we have to switch all secondary cores
into non-secure state also.
So we add an entry point for secondary CPUs coming out of low-power
state and make sure we put them into WFI again after having switched
to non-secure state.
For this we acknowledge and EOI the wake-up IPI, then go into WFI.
Once being kicked out of it later, we sanity check that the start
address has actually been changed (since another attempt to switch
to non-secure would block the core) and jump to the new address.
The actual CPU kick is done by sending an inter-processor interrupt
via the GIC to all CPU interfaces except the requesting processor.
The secondary cores will then setup their respective GIC CPU
interface.
While this approach is pretty universal across several ARMv7 boards,
we make this function weak in case someone needs to tweak this for
a specific board.
The way of setting the secondary's start address is board specific,
but mostly different only in the actual SMP pen address, so we also
provide a weak default implementation and just depend on the proper
address to be set in the config file.

The core specific part of the work is done in the assembly routine
in nonsec_virt.S, introduced with the previous patch, but for the full
glory we need to setup the GIC distributor interface once for the
whole system, which is done in C here.
The routine is placed in arch/arm/cpu/armv7 to allow easy access from
other ARMv7 boards.
We check the availability of the security extensions first.
Since we need a safe way to access the GIC, we use the PERIPHBASE
registers on Cortex-A15 and A7 CPUs and do some sanity checks.
Boards not implementing the CBAR can override this value via a
configuration file variable.
Then we actually do the GIC enablement:
a) enable the GIC distributor, both for non-secure and secure state
(GICD_CTLR[1:0] = 11b)
b) allow all interrupts to be handled from non-secure state
(GICD_IGROUPRn = 0xFFFFFFFF)
The core specific GIC setup is then done in the assembly routine.
