Early MMU improves performance especially on emulators. However, the
early MMU is left enabled after the first stage of SPL boot. Instead
of flushing D-cache and dealing with re-enabling MMU for the second
stage U-Boot, disabling it for SPL build simplifies the process. The
performance penalty is unnoticeable on the real hardware. As of now,
SPL boot is not supported by existing emulators. So this should have
no impact on emulators.

For ARMv8 Layerscape SoCs, secure memory and MC memorey are reserved
at the end of DDR. DDR is spit into two or three banks. This patch
reverts commit aabd7ddb and simplifies the calculation of reserved
memory, and moves the code into common SoC file. Secure memory is
carved out first. DDR bank size is reduced. Reserved memory is then
allocated on the top of available memory. U-Boot still has access
to reserved memory as data transferring is needed. Device tree is
fixed with reduced memory size to hide the reserved memory from OS.
The same region is reserved for efi_loader.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
U-Boot needs to set up available memory area(s) in dram_init() and
dram_init_banksize(). It is platform-dependent how to detect the
memory banks. Currently, UniPhier adopts the memory banks _alleged_
by DT. This is based on the assumption that users bind a correct DT
in their build process.
Come to think of it, the DRAM controller has already been set up
before U-Boot is entered (because U-Boot runs on DRAM). So, the
DRAM controller setup register seems a more reliable source of any
information about DRAM stuff. The DRAM banks are initialized by
preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever),
so this means the source of the reliability is shifted from Device
Tree to such early-stage firmware. However, if the DRAM controller
is wrongly configured, the system will crash. If your system is
running, the DRAM setup register is very likely to provide the
correct DRAM mapping.
Decode the SG_MEMCONF register to get the available DRAM banks.
The dram_init() and dram_init_banksize() need similar decoding.
It would be nice if dram_init_banksize() could reuse the outcome
of dram_init(), but global variables are unavailable at this stage
because the .bss section is available only after the relocation.
As a result, SG_MEMCONF must be checked twice, but a new helper
uniphier_memconf_decode() will help to avoid code duplication.

Cleanup stm32f7 files:
- use BIT macro
- use GENMASK macro
- use rcc struct instead of macro additions
Add missing stm32f7 register in rcc struct

This patch adds the DTS source files needed for stm32f746-disco board
The files are based on the stm32f429/469 files from current linux
kernel.
Source for "arch/arm/dts/armv7-m.dtsi": Linux: "arch/arm/boot/dts/armv7-m.dtsi"

The check for OMAP3630/3730 only checks for 800MHz 3630/3730, but
anything else is lumped into 36XX/37XX with an assumed 1GHz speed.
Based on the DM3730 TRM bit 9 shows the MPU Frequency (800MHz/1GHZ).
This also adds the ability to distinguish between the DM3730, DM3725,
AM3715, and AM3703 and correctly display their maximum speed.

This feature seems to be sometimes misunderstood. The intention is:
[1] Bring the slaves into the U-Boot proper image, not SPL (unless
you have a special reason to do otherwise).
[2] The operation must be done in a board (SoC) specific manner
since how to wake the slaves from the Boot ROM is SoC specific.
[3] The slaves must enter U-Boot proper after U-Boot relocates
itself because the "cpu-release-addr" property points to the
relocated memory area.
[2] is already explained in the help. We can make [1] even clearer
by mentioning "U-Boot proper" instead of "U-Boot". [3] is missing,
so I am adding it to the list. Instead, "before the master CPU
jumps to the kernel" is a matter of course, so removed.
