This generic $bootcmd, and associated support macros, automatically
searches a defined set of storage devices (or network protocols) for an
extlinux configuration file or U-Boot boot script in various standardized
locations. Distros that install such a boot config file/script in those
standard locations will get easy-to-set-up booting on HW that enables
this generic $bootcmd.
Boards can define the set of devices from which boot is attempted, and
the order in which they are attempted. Users may later customize this
set/order by edting $boot_targets.
Users may interrupt the boot process and boot from a specific device
simply by executing e.g.:
$ run bootcmd_mmc1
or:
$ run bootcmd_pxe
This patch was originally written by Dennis Gilmore based on Tegra and
rpi_b boot scripts. I have made the following modifications since then:
* Boards must define the BOOT_TARGET_DEVICES macro in order to specify
the set of devices (and order) from which to attempt boot. If needed,
we can define a default directly in config_distro_bootcmd.h.
* Removed $env_import and related variables; nothing used them, and I
think it's better for boards to pre-load an environment customization
file using CONFIG_PREBOOT if they need.
* Renamed a bunch of variables to suit my whims:-)

This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done
for sun7i only since I don't have access to any other sunxi platforms
with sata included.
The PHY setup is derived from the Alwinner releases and Linux, but is mostly
undocumented.
The Allwinner AHCI controller also requires some magic (and, again,
undocumented) DMA initialisation when starting a port. This is added under a
suitable ifdef.
This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on
contents of Linux DTS files, including SATA power pin config taken from the
DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

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.

We are about to switch to Kconfig in the next commit.
But there are something to get done beforehand.
In Kconfig, include/generated/autoconf.h defines boolean
CONFIG macros as 1.
CONFIG_SPL and CONFIG_TPL, if defined, must be set to 1.
Otherwise, when switching to Kconfig, the build log
would be sprinkled with warning messages like this:
warning: "CONFIG_SPL" redefined [enabled by default]

This patch moves some board specific NAND configs:
- FROM: generic config file 'ti_armv7_common.h'
- TO: individual board config files using these configs.
So that each board can independently set the value as per its design.
Following configs are affected in this patch:
CONFIG_SYS_NAND_U_BOOT_OFFS: <refer doc/README.nand>
CONFIG_CMD_SPL_NAND_OFS: <refer doc/README.falcon>
CONFIG_SYS_NAND_SPL_KERNEL_OFFS: <refer doc/README.falcon>
CONFIG_CMD_SPL_WRITE_SIZE: <refer doc/README.falcon>
This patch also updates documentation for few of above NAND configs.

Fixes commit a0a37183bd75e74608bc78c8d0e2a34454f95a91
ARM: omap: merge GPMC initialization code for all platform
1) NAND device are not directly memory-mapped to CPU address-space, they are
indirectly accessed via following GPMC registers:
- GPMC_NAND_COMMAND_x
- GPMC_NAND_ADDRESS_x
- GPMC_NAND_DATA_x
Therefore from CPU's point of view, NAND address-map can be limited to just
above register addresses. But GPMC chip-select address-map can be configured
in granularity of 16MB only.
So this patch uses GPMC_SIZE_16M for all NAND devices.
2) NOR device are directly memory-mapped to CPU address-space, so its
address-map size depends on actual addressable region in NOR FLASH device.
So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map
size configuration.

Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and
add KS2_ prefix where it's needed. It requires to change names also
in places where they're used. Align lines and remove redundant
definitions in kardware-k2hk.h at the same time.
Using common KS2_ prefix helps resolve redundant redefinitions and
adds opportunity to use KS2_ definition across a project not thinking about
what SoC should be used. It's more convenient and we don't need to worry
about the SoC type in common files, hardware.h will think about that.
The hardware.h decides definitions of what SoC to use.

The Keystone SoCs use the same NAND driver as Davinci.
This patch adds opportunity to write Keystone U-boot image to NAND
device using appropriate RBL ECC layout. This is needed only if RBL
boots U-boot from NAND device and that's supposed that raw u-boot
partition is used only for writing image.
The main problem is that default Davinci ECC layout is different from
Keystone RBL layout. To read U-boot image the RBL needs that image was
written using RBL ECC layout.
The BBT table is written using default Davinci layout and has to
be updated using one. The BBT can be updated only while erasing
chip or by forced bad block assigning, so erase function has to
use native ecc layout in order to be able to write BBT correctly.
So if we're writing to NAND U-boot address we use RBL layout for
others we use default ECC layout.
Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no
reasons to use ECC layout commands. It was added by mistake.
