Make sure to call unmap_sysmem() for address allocated by map_sysmem()
before leaving the function; however this patch gives no impact on
the behavior because map_sysmem()/unmap_sysmem() does nothing except
on Sandbox. Sandbox never runs this code because "booti" is a command
for booting ARM64 kernel image.

internal memory (0x0c000000). Secure devices uses this memory and
CONFIG_SYS_TEXT_BASE has to be different for those devices.

The Raspberry Pi 3 contains a BCM2837 SoC. The BCM2837 is a BCM2836 with
the CPU complex swapped out for a quad-core ARMv8. This can operate in 32-
or 64-bit mode. 32-bit mode is the current default selected by the
VideoCore firmware on the Raspberry Pi 3. This patch adds a 32-bit port of
U-Boot for the Raspberry Pi 3.
>From U-Boot's perspective, the only delta between the RPi 2 and RPi 3 is a
change in usage of the SoC UARTs. On all previous Pis, the PL011 was the
only UART in use. The Raspberry Pi 3 adds a Bluetooth module which uses a
UART to connect to the SoC. By default, the PL011 is used for this purpose
since it has larger FIFOs than the other "mini" UART. However, this can
be configured via the VideoCore firmware's config.txt file. This patch
hard-codes use of the mini UART in the RPi 3 port. If your system uses the
PL011 UART for the console even on the RPi 3, please use the RPi 2 U-Boot
port instead. A future change might determine which UART to use at
run-time, thus allowing the RPi 2 and RPi 3 (32-bit) ports to be squashed
together.
The mini UART has some limitations. One externally visible issue in the
BCM2837 integration is that the UART divides the SoC's "core clock" to
generate the baud rate. The core clock is typically variable, and under
control of the VideoCore firmware for thermal management reasons. If the
VC FW does modify the core clock rate, UART communication will be
corrupted since the baud rate will vary from the expected value. This was
not an issue for the PL011 UART, since it is fed by a fixed 3MHz clock. To
work around this, the VideoCore firmware can be told not to modify the SoC
core clock. However, the only way this can happen and be thermally safe is
to limit the core clock to a low/minimum frequency. This leaves
performance on the table for use-cases that don't care about a UART
console. Consequently, use of the mini UART console must be explicitly
requested by entering the following line into config.txt:
enable_uart=1
A recent version of the VC firmware is required to ensure that the mini
UART is fully and correctly initialized by the VC FW; at least
firmware.git 046effa13ebc "firmware: arm_loader: emmc clock depends on
core clock See: https://github.com/raspberrypi/firmware/issues/572".

This allows U-Boot to known the name of the board.
The existing rpi_2_defconfig can operate correctly on the Raspberry Pi 3
in 32-bit mode /if/ you have configured the firmware to use the PL011 UART
as the console UART (the default is the mini UART). This requires two
things:
a) config.txt should contain dtoverlay=pi3-miniuart-bt
b) You should run the following to tell the VC FW to process DT when
booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD card
as the kernel image:
path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img
This works as of firmware.git commit 046effa13ebc "firmware: arm_loader:
emmc clock depends on core clock See:

To simplify support for new SoCs, just use a constant filename
for the unknown case. In practice this case shouldn't be hit anyway, so
the filename isn't relevant, and certainly doesn't need to differentiate
between SoCs. If a user has an as-yet-unknown board, they can override
this value in the environment anyway.

NOTE: Few of these might have default configurations, however,
since most are software configurable, it is better to explicitly
configure the system to have a known default state.
Without programming these, we end up seeing lack of coherency on certain
peripherals resulting in inexplicable failures (such as USB peripheral's
DMA data not appearing on ARM etc and weird workarounds being done by
drivers including cache flushes which tend to have system wide
performance impact).
By marking these segments as shared, we also ensure SoC wide coherency
is enabled.

MSMC segment Privilege ID is not consistent accross the keystone2 SoCs.
As the first step to ensure complete SoC wide coherency setup, lets
refactor the macros to remove the #if-deffery around the code which
obfuscates which IDs are actually enabled for which SoC.
As a result of this change the PCIe configuration is moved after the
msmc configuration is complete, but that should ideally have no
functional impact.
