In order to enable cpsw on AM335x ICEv2 board, the following needs to be done:
1)There are few on board jumper settings which gives a choice between
cpsw and PRUSS, that needs to be properly selected[1]. Even after selecting
this, there are few GPIOs which control these muxes that needs to be held high.
2) The clock to PHY is provided by a PLL-based clock synthesizer[2] connected
via I2C. This needs to properly programmed and locked for PHY operation.
And PHY needs to be reset before before being used, which is also held by
a GPIO.
3) RMII mode needs to be selected.

After booting has finished, EFI allows firmware to still interact with the OS
using the "runtime services". These callbacks live in a separate address space,
since they are available long after U-Boot has been overwritten by the OS.
This patch adds enough framework for arbitrary code inside of U-Boot to become
a runtime service with the right section attributes set. For now, we don't make
use of it yet though.
We could maybe in the future map U-boot environment variables to EFI variables
here.

As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax. (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason. Actually,
for CONFIG_DM*, we have no good reason to do so.
Generally, CONFIG_DM is not a user-configurable option. Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it. Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.
Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.
This commit prefers "select" and cleans up the following issues.
[1] Never use "CONFIG_DM=n" in defconfig files
It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set". But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird. Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.
[2] Delete redundant CONFIGs
Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

This option has a bool type, not hex.
Fix it and enable it if CONFIG_DM is on because Driver Model always
requires malloc memory. Devices are scanned twice, before/after
relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc
memory before relocation. As it is board-independent, handle it
globally.

This patch adds support of NOR cape[1] for both Beaglebone (white) and
Beaglebone(Black) boards. NOR Flash on this cape is connected to GPMC
chip-select[0] and accesses as external memory-mapped device.
This cape has 128Mbits(16MBytes), x16, CFI compatible NOR Flash device.
As GPMC chip-select[0] can be shared by multiple capes so NOR profile is
not enabled by default in boards.cfg. Following changes are required to
enable NOR cape detection when building am335x_boneblack board profile.

Beaglebone Board can be connected to expansion boards to add devices to them.
These expansion boards are called 'capes'. This patch adds support for
following versions of Beaglebone(AM335x) NAND capes
(a) NAND Device with bus-width=16, block-size=128k, page-size=2k, oob-size=64
(b) NAND Device with bus-width=16, block-size=256k, page-size=4k, oob-size=224

* How to boot from NAND using Memory Expander + NAND Cape ? *
- Important: As BOOTSEL values are sampled only at POR, so after changing any
setting on SW2 (DIP switch), disconnect and reconnect all board power supply
(including mini-USB console port) to POR the beaglebone.
- Selection of ECC scheme
for NAND cape(a), ROM code expects BCH8_HW ecc-scheme
for NAND cape(b), ROM code expects BCH16_HW ecc-scheme
- Selction of boot modes can be controlled via DIP switch(SW2) present on
Memory Expander cape.
SW2[SWITCH_BOOT] == OFF follow default boot order MMC-> SPI -> UART -> USB
SW2[SWITCH_BOOT] == ON boot mode selected via DIP switch(SW2)
So to flash NAND, first boot via MMC or other sources and then switch to
SW2[SWITCH_BOOT]=ON to boot from NAND Cape.
- For NAND boot following switch settings need to be followed
SW2[ 1] = OFF (SYSBOOT[ 0]==1: NAND boot mode selected )
SW2[ 2] = OFF (SYSBOOT[ 1]==1: -- do -- )
SW2[ 3] = ON (SYSBOOT[ 2]==0: -- do -- )
SW2[ 4] = ON (SYSBOOT[ 3]==0: -- do -- )
SW2[ 5] = OFF (SYSBOOT[ 4]==1: -- do -- )
SW2[ 6] = OFF (SYSBOOT[ 8]==1: 0:x8 device, 1:x16 device )
SW2[ 7] = ON (SYSBOOT[ 9]==0: ECC done by ROM )
SW2[ 8] = ON (SYSBOOT[10]==0: Non Muxed device )
SW2[ 9] = ON (SYSBOOT[11]==0: -- do -- )

*IMPORTANT NOTE*
As Beaglebone board shares the same config as AM335x EVM, so following
changes are required in addition to this patch for Beaglebone NAND cape.
(1) Enable NAND in am335x_beaglebone board profile
(2) Add CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config because:
- AM335x EVM has NAND device with datawidth=8, whereas
- Beaglebone NAND cape has NAND device with data-width=16
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.
The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.
After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.
TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

This commit adds:

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/.

As noted by clang, we have been shifting certain values out of 32bit
range when setting some DDR registers. Upon further inspection these

from historical bring-up code and can be discarded. Similarly, we had
been declaring some fields as 0 when they will be initialized that way.
