Add API to save boot parameters passed from BL31
Use assembly implementation of save_boot_params instead of c function.
Because generally ATF does not set up SP_EL2 on exiting.
Thus, usage of a C function immediately after exiting with no stack
setup done by ATF explicitly, may cause SP_EL2 to be not sane,
which in turn causes a crash if this boot was not lucky to get
an SP_EL2 in valid range. Replace C implementation with assembly one
which does not use stack this early, and let u-boot to set up its stack
later.

arm: qemu: override flash accessors to use virtualizable instructions
Some instructions in the ARM ISA have multiple output registers, such
as ldrd/ldp (load pair), where two registers are loaded from memory,
but also ldr with indexing, where the memory base register is incremented
as well when the value is loaded to the destination register.
MMIO emulation under KVM is based on using the architecturally defined
syndrome information that is provided when an exception is taken to the
hypervisor. This syndrome information describes whether the instruction
that triggered the exception is a load or a store, what the faulting
address was, and which register was the destination register.
This syndrome information can only describe one destination register, and
when the trapping instruction is one with multiple outputs, KVM throws an
error like
kvm [615929]: Data abort outside memslots with no valid syndrome info
on the host and kills the QEMU process with the following error:
This means that, in order to run U-Boot in QEMU under KVM, we need to
avoid such instructions when accessing emulated devices. For the flash
in particular, which is a hybrid between a ROM (backed by a read-only
KVM memslot) when in array mode, and an emulated MMIO device (when in
write mode), we need to take care to only use instructions that KVM can
deal with when they trap.
So override the flash read accessors that are used when running on QEMU
under KVM. Note that the the 64-bit wide read and write accessors have
been omitted: they are never used when running under QEMU given that it
does not emulate CFI flash that supports it.

arm: qemu: disable the EFI workaround for older GRUB
The QEMU/mach-virt targeted port of u-boot currently only runs on
QEMU under TCG emulation, which does not model the caches at all,
and so no users can exist that are relying on the GRUB hack for
EFI boot.
We will shortly enable support for running under KVM, but the GRUB
hack (which disables all caches without doing cache cleaning by VA
during ExitBootServices()) is likely to cause more problems than it
solves, given that KVM hosts require correct maintenance if they
incorporate non-architected system caches.
So let's disable the GRUB hack by default on the QEMU/mach-virt

QEMU's mach-virt machine only supports selecting CPU models that
implement the virtualization extensions, and are therefore guaranteed
to support LPAE as well.
Initially, QEMU would not allow emulating these CPUs running in HYP
mode (or EL2, for AArch64), but today, it also contains a complete
implementation of the virtualization extensions themselves.
This means we could be running U-Boot in HYP mode, in which case the
LPAE long descriptor page table format is the only format that is
supported. If we are not running in HYP mode, we can use either.
So let's enable CONFIG_ARMV7_LPAE for qemu_arm_defconfig so that we
get the best support for running with the MMU and caches enabled at
any privilege level.

IPQ40xx series have 4x Cortex A7 ARM-v7A cores.
Supported are: IPQ4018, IPQ4019, IPQ4028 and IPQ4029.
IPQ40x8 and IPQ40x9 use the same cores, but differ in
addressable RAM size (1GB for IPQ40x9 and 256MB for IPQ40x8)
and supported peripherals (IPQ40x8 lacks RGMII, LCD controller
and EMMC/SDHCI controllers).
IQP4028/IPQ4029 models differ from IPQ4018/IPQ4019 only
by their rated temperatures rates with IPQ402X models being
rated for wider temperature ranges.
Initially this supports:
* Simple clock driver (Only for UART1 now, will be extended)
* Pinctrl driver (Supports UARTX and GPIO now, will be extended)
* GPIOs already supported by msm_gpio driver with updates
* UARTs already supported by serial_msm driver with updates
