AM654 HyperBus controller provides MMIO interface to read data from
flash. So add DMA memcpy support for reading data over MMIO interface.
This provides 5x improvement in throughput and reduces CPU usage as
well.

Since commit 7484c727b636 ("ARM: realview: delete the RealView board

The ARM SP804 supports a maximum of 32-bit counter, but Hisilicon extends
it to 64-bit. That means, the registers: TimerXload, TimerXValue and

From: Zhen Lei
A 100MHZ 32-bit timer will be wrapped up less than 43s. Although the
kernel maintains a software high 32-bit count in the tick IRQ. But it's
not applicable to the user mode APPs.
Note: The kernel still uses the lower 32 bits of the timer.

Add two local variables: timer1_base and timer2_base in sp804_of_init(),
to avoid repeatedly calculate the base address of timer2, and make it
easier to recognize timer1. Hope to make the next patch looks more clear.
No functional change.

pci_epc_get_first_free_bar() uses only "reserved_bar" member in
epc_features to get the first unreserved BAR. However if the
reserved BAR is also a 64-bit BAR, then the next BAR shouldn't be
returned (since 64-bit BAR uses two BARs).
