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.

Clock Driver
This driver is ast2500-specific and is not compatible with earlier
versions of this chip. The differences are not that big, but they are
in somewhat random places, so making it compatible with ast2400 is not
worth the effort at the moment.
SDRAM MC driver
The driver is very ast2500-specific and is completely incompatible
with previous versions of the chip.
The memory controller is very poorly documented by Aspeed in the
datasheet, with any mention of the whole range of registers missing. The
initialization procedure has been basically taken from Aspeed SDK, where
it is implemented in assembly. Here it is rewritten in C, with very limited
understanding of what exactly it is doing.

The LS1046AQDS processor has three integrated USB 3.0 controllers
(USB1, USB2, and USB3) that allow direct connection to the USB
ports with appropriate protection circuitry and power supplies.
USB1 and USB2 ports are powered by a NX5P2190UK device, which
supplies 5v power at up to 1.2 A. The power enable and
power-fault-detect pins are connected to the LS1046A processor
via CPLD for individual port management.

The sdhci controller assumes that the base clock frequency is fully supported by

We may want to run different firmware before running U-Boot. For
example, ARM Trusted Firmware runs before U-Boot, making U-Boot
a non-secure world boot loader. In this case, the SoC might be
initialized there, which enables us to skip SPL entirely.
This commit removes "select SPL" to make it configurable. This
also enables the Multi SoC support for the UniPhier ARMv8 SoCs.
(CONFIG_ARCH_UNIPHIER_V8_MULTI) Thanks to the driver model and
Device Tree, the U-Boot proper part is now written in a generic way.
The board/SoC parameters reside in DT. The Multi SoC support
increases the memory footprint a bit, but the U-Boot proper does
not have strict memory constraint. This will mitigate the per-SoC
(sometimes per-board) defconfig burden.

When falcon mode support was added, it was right around when SPL_OS_BOOT
was migrated to Kconfig. So first we must move the enablement to the

that the board compiles after 5d28b930f237.

In 35fc84f, bootm was refactored so plain 'bootm' and
'bootm <subcommand>' shared a common implementation.
The 'bootm ramdisk' command implementation is now part of the common
implementation but not invoke by plain 'bootm' since the original
implementation never did ramdisk relocation. Instead, ramdisk
relocation happened in image_setup_linux() which is typically called
during the OS portion of 'bootm'.
On ARM, parameters to the Linux kernel can either be passed by FDT or
ATAGS. When using FDT, image_setup_linux() is called which also triggers
ramdisk relocation. When using ATAGS, image_setup_linux() is _not_
called because it mostly does FDT setup.
Instead of calling image_setup_linux() in both FDT and ATAGS cases,
include BOOTM_STATE_RAMDISK in the requested states during a plain
'bootm' if CONFIG_SYS_BOOT_RAMDISK_HIGH is set and remove the ramdisk
relocation from image_setup_linux(). This causes ramdisk relocation to
happen on any system where CONFIG_SYS_BOOT_RAMDISK_HIGH regardless of
the OS being booted. Also remove IMAGE_ENABLE_RAMDISK_HIGH as it was
only used by the now-removed code from image_setup_linux().

commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor"

sending to the board.
Since the above patch, you have to setup the fcr register.
For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...
This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.
Detected this issue with automated tbot tests on am335x

The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)
