Current AM57xx evm supports both BeagleBoard-X15

The AM572x EValuation Module(EVM) provides an affordable platform to

(AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI,
machine vision, networking, medical imaging and many other industrial

Since the EEPROM contents are compatible between the BeagleBoard-X15 and
the AM57xx-evm, we add support for the detection logic to enable
support for various user programmable scripting capability.
NOTE: U-boot configuration is currently a superset of AM57xx evm and

Several TI EVMs have EEPROM that can contain board description information
such as revision, DDR definition, serial number, etc. In just about all
cases, these EEPROM are on the I2C bus and provides us the opportunity
to centralize the generic operations involved.
The on-board EEPROM on the BeagleBone Black, BeagleBone, AM335x EVM,
AM43x GP EVM, AM57xx-evm, BeagleBoard-X15 share the same format.
However, DRA-7* EVMs, OMAP4SDP use a modified format.
We hence introduce logic which is generic between these platforms
without enforcing any specific format. This allows the boards to use the
relevant format for operations that they might choose.
This module will compile for all TI SoC based boards when
CONFIG_TI_I2C_BOARD_DETECT is enabled to have optimal build times for
platforms that require this support.
It is important to note that this logic is fundamental to the board
configuration process such as DDR configuration which is needed in
SPL, hence cannot be part of the standard u-boot driver model (which
is available later in the process). Hence, to aid efficiency, the
eeprom contents are copied over to SRAM scratchpad memory area at the
first invocation to retrieve data.
To prevent churn with cases such as DRA7, where eeprom format maybe
incompatible, we introduce a generic common format in eeprom which
is made available over accessor functions for usage.
Special handling for BBG1 EEPROM had to be introduced thanks to the
weird eeprom rev contents used.
The follow on patches introduce the use of this library for AM335x,
AM437x, and AM57xx.

BeagleBoard X15 (http://beagleboard.org/x15) support in u-boot does
actually support two different platform configuration offered by
TI. In addition to BeagleBoard X15, it also supports the TMDXEVM5728
(or more commonly known as AM5728-evm).
Information about the TI AM57xx EVM can be found here
http://www.ti.com/tool/tmdxevm5728
The EVM configuration is 1-1 compatible with BeagleBoard X15 with the
additional support for mPCIe, mSATA, LCD, touchscreen, Camera, push
button and TI's wlink8 offering.
Hence, we rename the beagle_x15 directory to am57xx to support TI
EVMs that use the AM57xx processor. By doing this we have common code
reuse. This sets the stage to have a common u-boot image solution for
multiple TI EVMs such as that already done for am335x and am437x. This
sets the stage for upcoming multiple TI EVMs that share the same code
base.
NOTE: Commit eae7ae1853 ("am437x: Add am57xx_evm_defconfig using
CONFIG_DM") introduced DT support for beagle_x15 under am57xx_evm
platform name. However, this ignored the potential confusion arising for
users as a result. To prevent this, existing beagle_x15_defconfig is
renamed as am57xx_evm_nodt_defconfig to denote that this is the "non
device tree" configuration for the same platform. We still retain
am57xx-beagle-x15.dts at this point, since we just require the common
minimum dts.
As a result of this change, users should expect changes in build
procedures('make am57xx_evm_nodt_defconfig' instead of 'make
beagle_x15_defconfig'). Hopefully, this would be a one-time change.

The recent changes for hw leveling on am33xx were not intended for
DDR2 boards, only DDR3. Update emif_sdram_type to take a sdram_config
value to check against. This lets us pass in the value we would use to
configure, when we have not yet configured the board yet. In other cases
update the call to be as functional as before and check an already
programmed value in.

This patch populates serial number environment variable from
die_id_0 and die_id_1 register values for DRA7xx boards.
The function is added in omap common code so that this can be re-used.
Serial# environment variable will be useful to show correct
information in "fastboot devices" commands.

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.

Commit d3cfcb3 (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY)
changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl
to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl
to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between
the two dwc3 controllers present in dra7xx/am43xx and enabled these
clocks in enable_basic_clocks() in hw_data.c. However these clocks
continued to be enabled in board files/driver files for dwc3 host
mode functionality causing compilation break with few configs.
Fixed it here by making all the clocks enabled in enable_basic_clocks()
and removing it from board files/driver files here.

Since we support multiple dwc3 controllers to be existent at the same
time, in order to handle the interrupts of a particular dwc3 controller
usb_gadget_handle_interrutps should take controller index as an
argument.
Hence the API of usb_gadget_handle_interrupts is modified to take
controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.

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.
