This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.
Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

This is a workaround for 32 bit hardware limitation of TDM.
T1040 has 36 bit physical addressing, TDM DMAC register

which lies beyond 32 bit address range. This workaround
creats a LAW to enable access of TDM DMA to CCSR by
mapping CCSR to overlap with DDR.

workaround law is set only if "tdm" is defined in hwconfig.

A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to
increase and cause the PLL to unlock when the temperature delta from the
time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V
(or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC
VCO. Only the protocols using Ring VCOs are impacted.
Workaround:
For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need
to use alternate serdes protocols. The alternate option has the same
functionality as the original option; the only difference being LC VCO
rather than Ring VCO.

We only need u-boot to bother about a single core in the QEMU machine.
Everything that would require additional knowledge of more cores gets
handled by QEMU and passed straight into the payload we execute.
Because of this setup, it would be counterproductive to enable SMP support
in u-boot. We would have to rip CPUs out of already existing spin tables
and respin them from u-boot. It would be a pretty big mess.
So only assume we have a single core. This fixes errors about CONFIG_MP
