e2924e5904 ARM: k2g: Configure reset mux to device reset
BOOTCFG_RSTMUX8 register controls the reset mux associated with the ARM.
Timer5(dedicated to ARM) when used as WatchDog timer, the events it
generates are routed to the above mux.

Following are the 3 events that can controlled bt the reset mux:
- Device Reset
- An interrupt to the ARM_GIC
- An interrupt to the ARM_GIC followed by a device reset.

Right now to give a default watchdog behaviour "Device reset" is
being selected.

e42523f544 ARM: DRA7: Consolidate voltage macros across different SoCs
The voltage values for each voltage domain at an OPP is identical
across all the SoCs in the DRA7 family. The current code defines
one set of macros for DRA75x/DRA74x SoCs and another set for DRA72x
macros. Consolidate both these sets into a single set.

This is done so as to minimize the number of macros used when voltage
values will be added for other OPPs as well.

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.

uart3 as default serial console. In order to boot to prompt, concole in both

qspiboot_defconfig:

since they are available long after U-Boot has been overwritten by the OS.

8efc243741 ARM: keystone2: use detected ddr3a size
Because KS2 u-boot works in 32 bit address space the existing ram_size
global data field cannot be used. The maximum, which the get_ram_size()
can detect is 2GB only. The ft_board_setup() needs the actual ddr3 size
to fix up dtb.

This commit introduces the ddr3_get_size() which uses SPD data to
calculate the ddr3 size. This function replaces the "ddr3_size"
environment variable, which was used to get the SODIMM size.

For platforms, which don't have SODIMM with SPD and ddr3 is populated to
a board a simple ddr3_get_size function that returns ddr3 size has to be
implemented. See hardware-k2l.h

212f96f6bd board: ti: AM57xx: Add detection logic for AM57xx-evm
Current AM57xx evm supports both BeagleBoard-X15
(http://beagleboard.org/x15) and AM57xx EVM
(http://www.ti.com/tool/tmdxevm5728).

The AM572x EValuation Module(EVM) provides an affordable platform to
quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors
(AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI,
machine vision, networking, medical imaging and many other industrial
applications. This EVM is based on the same BeagleBoard-X15 Chassis
and adds mPCIe, mSATA, LCD, touchscreen, Camera, push button and TI's
wlink8 offering.

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
BeagleBoard-X15 and no additional configuration tweaking is needed.

This change also sets up the stage for future support of TI AM57xx EVMs
to the same base bootloader build.

0bea813d00 ARM: omap-common: Add standard access for board description EEPROM
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.

74cc8b097d board: ti: beagle_x15: Rename to indicate support for TI am57xx evms
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.

76cff2b108 ARM: DRA74-evm: Use SMA_1 spare register to workaround DP83865 phy on SR2.0
DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet
provided IODELAY values for standard RGMII phys do not work.

Silicon Revision(SR) 2.0 provides an alternative bit configuration
that allows us to do a "gross adjustment" to launch the data off a
different internal clock edge. Manual IO Delay overrides are still
necessary to fine tune the clock-to-data delays. This is a necessary
workaround for the quirky ethernet Phy we have on the platform.

NOTE: SMA registers are spare "kitchen sink" registers that does
contain bits for other workaround as necessary as well. Hence the
control for the same is introduced in a generic SoC specific, board
generic location.

16fc0f8ee3 ARM: beagle_x15: prevent DCAN1 _wait_target_disable failure in kernel
If board is booted with transitions happening on DCAN1 pins then
the following warning is seen in the kernel at boot when the
hwmod layer initializes.

"omap_hwmod: dcan1: _wait_target_disable failed"

This is because DCAN1 module's SWAKEUP mechanism is broken
and it fails to correctly turn OFF if it sees a transition on the
DCAN1 pins. Suggested workaround is to keep DCAN1 pins in safe mode
while enabling/disabling DCAN1 module.

The hwmod layer enables and disables all modules at boot
and we have no opportunity to put the DCAN1 pins in safe mode
at that point.

DCAN1 is not used by u-boot so it doesn't matter to it if these
pins are in safe mode. The kernel driver correctly configures
the right mode when DCAN1 is active.

58d423b88e dm: select CONFIG_DM* options
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.

The value in SDRAM_REF_CTRL controls the delay time between
the initial rising edge of DDR_RESETn to rising edge of DDR_CKE
(JEDEC specs this as 500us). In order to achieve this, SDRAM_REF_CTRL

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

89f44bb0ce keystone2: ecc: add ddr3 error detection and correction support
This patch adds the DDR3 ECC support to enable ECC in the DDR3
EMIF controller for Keystone II devices.

By default, ECC will only be enabled if RMW is supported in the
DDR EMIF controller. The entire DDR memory will be scrubbed to
zero using an EDMA channel after ECC is enabled and before
u-boot is re-located to DDR memory.

An ecc_test environment variable is added for ECC testing.
If ecc_test is set to 0, a detection of 2-bit error will reset
the device, if ecc_test is set to 1, 2-bit error detection
will not reset the device, user can still boot the kernel to
check the ECC error handling in kernel.

9352697aa0 board/ti/dra7xx: add support for parallel NOR
This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM.
The Flash device is connected to GPMC controller on chip-select[0] and accessed
as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and
is CFI compatible.

As multiple devices are share GPMC pins on this board, so following board
settings are required to detect NOR device:
     SW5.1 (NAND_BOOTn) = OFF (logic-1)
     SW5.2 (NOR_BOOTn)  = ON  (logic-0) /* Active-low */
     SW5.3 (eMMC_BOOTn) = OFF (logic-1)
     SW5.4 (QSPI_BOOTn) = OFF (logic-1)

And also set appropriate SYSBOOT configurations:
     SW3.1 (SYSBOOT[ 8])= ON  (logic-1) /* selects SYS_CLK1 speed */
     SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */
     SW3.3 (SYSBOOT[10])= ON  (logic-1) /* wait-pin monitoring = enabled */

e53ad4b445 board/ti/am43xx: add support for parallel NAND
This patch adds support for NAND device connected to GPMC chip-select on
following AM43xx EVM boards.

am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a
  time either eMMC or NAND can be enabled. Selection between eMMC and NAND is
  controlled by:
  (a) Statically using Jumper on connecter (J89) present on board.
  (a) If Jumper on J89 is NOT used, then selection can be dynamically controlled
      by driving SPI2_CS0[MUX_MODE=GPIO] pin via software:
      SPI2_CS0 == 0: NAND (default)
      SPI2_CS0 == 1: eMMC

am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI,
  Thus only one of the two can be used at a time. Selection is controlled by:
  (a) Dynamically driving following GPIO pin from software
      GPMC_A0(GPIO) == 0 NAND is selected (default)

NAND device (MT29F4G08AB) on these boards has:
 - data-width=8bits
 - blocksize=256KB
 - pagesize=4KB
 - oobsize=224 bytes
For above NAND device, ROM code expects the boot-loader to be flashed in BCH16
ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs.

85eb0de214 board/ti/am335x: add support for beaglebone NAND cape
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
Further information and datasheets can be found at [1] and [2]

* 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 --      )

[2] http://beagleboardtoys.info/index.php?title=BeagleBone_4Gb_16-Bit_NAND_Module

*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

dd84058d24 kconfig: add board Kconfig and defconfig files
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/.

7a5f71bc40 am43xx_evm: Add qspiboot target
The ePOS EVM and EVM SK have QSPI as an option to boot.  Add a qspiboot
target that utilizes QSPI for env and so forth as an example of best
practices.  As QSPI is booted from directly we need to chang
CONFIG_SYS_TEXT_BASE.

Note that on ePOS EVM the QSPI and NAND are mutually exclusive choices
we need to handle that elsewhere, once NAND support is also added.

values, but don't care which it is, so perform a fixup on the QSPI_4

QSPI as a boot device in deployment.  When we boot from QSPI, we can

8a0c6d6fa9 OMAP: common: consolidate fake USB ethernet MAC address creation
TI platforms such as OMAP5uevm, PandaBoard, use equivalent
logic to generate fake USB MAC address from device unique DIE ID.

Consolidate this to a generic location such that other TI platforms such
as BeagleBoard-XM can also use the same.

NOTE: at this point in time, I dont yet see a need for a generic dummy
ethernet MAC address creation function, but if there is a need in the
future, this can be further abstracted out.
