Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.
In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.

UART_IBRD, UART_FBRD, and UART_LCR_H form a single 30-bit wide register which
is updated on a single write strobe generated by a UART_LCR_H write. So, to
internally update the content of UART_IBRD or UART_FBRD, a write to UART_LCR_H
must always be performed at the end.

Enable ENV_IS_IN_FAT so that the environment can be stored persistently.
It's stored in the FAT partition that the RPi firmware requires. On most
RPis, this is on the SD card (which must be present in order for the
system to boot). On the CM this is on the built-in eMMC device.
Since we now have a persistent environment, there's no need to load
uEnv.txt at boot; we only did that to work around the lack of persistent
environment.

Detect the board revision early during boot, and print the decoded
model name.
Eventually, this information can be used for tasks such as:
- Allowing/preventing USB device mode; some models have a USB device on-
board so only host mode makes sense. Others connect the SoC directly
to the USB connector, so device-mode might make sense.
- The on-board USB hub/Ethernet requires different GPIOs to enable it,
although luckily the default appears to be fine so far.
- The compute module contains an on-board eMMC device, so we could store
the environment there. Other models use an SD card and so don't support
saving the environment (unless we store it in a file on the FAT boot
partition...)
Set $fdtfile based on this information. At present, the mainline Linux
kernel doesn't contain a separate DTB for most models, but I hope that
will change soon.

Currenly when CONFIG_BOOTP_SERVERIP is defined, the SERVERIP is not changed

As we will load the BOOTFILE from SERVERIP, if the BOOTFILE is modified
by bootp packet but SERVERIP is not, that is not make sense.
This patch make SERVERIP and BOOTFILE be consistent. If we define the

Commit 709ea54 made a subtle change to the way the U-Boot API jump table
is set up. So at present putc(), getc(), tstc() and puts() do not work
correctly from functions that use the U-Boot API.
Previously these were set to the stdio functions, but these now take a
parameter specifying which stdio device to use. Instead, we should change
them to use the global functions which do not have a parameter.
This is a slight change in behaviour. The functions will now output to
all selected stdio devices - for example putc() will output a character to
all devices selected by stdout. However in most cases there is only one,
and it isn't necessarily incorrect behaviour anyway.
The API version is not changed since it is compatible with what was there
before.

Due to an uninitialised variable, when muxes were deselected, any value
could be written to the mux control register. On the PCA9548, this could
result in multiple channels being selected, thus enabling multiple
pull-up resistors, and much bus capacitance.

This patch adds the driver for the Designware master SPI controller. This
IP core is integrated on the Altera SoCFPGA. This implementation is a
driver model (DM) implementation. So multiple SPI drivers can be used.
Thats necessary, since SoCFPGA also integrates the Cadence QSPI controller
used to connect the SPI NOR flashes. Without DM, using multiple SPI
drivers is not possible.
This driver is very loosely based on the Linux driver. Most of the Linux
driver is removed. Only the polling loop for the transfer is really used
from this driver, as we don't support interrupts and DMA right now.
This is tested on the SoCrates SoCFPGA board using the SPI pins on the
P14 header.

With this driver enabled for SoCFPGA, access to SPI NOR flash is

The configuration (page size, timing info) will be taken from the
DT. See socrates as an example.
This QSPI supports depends on DT. So QSPI is only enabled if
CONFIG_OF_CONTROL is defined (see socfpga_socrates_defconfig).

This driver is cloned from the Altera Rockerboard.org U-Boot
repository. I used this git tag: ACDS14.0.1_REL_GSRD_RC2. With Some
modification to support the U-Boot driver model (DM).
As mentioned above, in this new version I ported this driver to the
new driver model (DM). One big advantage of this move is that now
multiple SPI drivers can be enabled on one platform. And since the
SoCFPGA also has the Designware SPI master controller integrated,
this feature is really needed to support both controllers.
Because of this, this series needs the DT support for SoCFPGA
to be applied. For DT based probing in the SPI DM.
