0a9e34056f gpio: omap: Drop 'method' parameter
The "method" parameter was part of the original port of the driver from
the kernel.  At some point this may have been added to allow for future
differentiation (as omap1 and omap2 have different GPIO IP blocks, so
this wasn't an unreasonable thing to do).  At this point however it's
just extra overhead, so drop.

0257930ba0 LG Optimus Black (P970) codename sniper support
The LG Optimus Black (P970) codename sniper is a smartphone that was designed
and manufactured by LG Electronics (LGE) and released back in 2011.

It is using an OMAP3630 SoC GP version, which allows running U-Boot and the
U-Boot SPL from the ground up. This port is aimed at running an Android version
such as Replicant, the fully free Android distribution. However, support for
upstream Linux with device-tree and common GNU/Linux distros boot commands
could be added in the future.

For more information about the journey to freeing this device, please read the

a08af85f46 omap3: Reboot mode support
Reboot mode is written in scratchpad memory before reboot in the form of a
single char, that is the first letter of the reboot mode string as passed to the
reboot function.

This mechanism is supported on OMAP3 both my the upstream kernel and by various
TI kernels.

It is up to each board to make use of this mechanism or not.

60c7c30aa0 omap-common: Common boot code OMAP3 support and cleanup
This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.

First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.

The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.

The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.

All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.

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.

326a682358 malloc_f: enable SYS_MALLOC_F by default if DM is on
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.

b050898efa omap: gpmc: 'nandecc sw' can use HAM1 or BCH8
The 'nandecc sw' command selects a software-based error correction
algorithm.  By default, this is OMAP_ECC_HAM1_CODE_SW but some
platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their
software-based correction algorithm.  Allow a user to be specific e.g.
 # nandecc sw <hamming|bch8>
where 'hamming' is still the default.

Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set
      to a hardware-based ECC scheme---a little strange when the user
      has requested 'sw' ECC.

7ae8350f67 ti: armv7: Move SPL SDRAM init to the right place, drop unused CONFIG_SPL_STACK
Currently in some cases SDRAM init requires global_data to be available
and soon this will not be available prior to board_init_f().  Adjust the
code paths in these cases to be correct.  In some cases we had the SPL
stack be in DDR as we might have large stacks (due to Falcon Mode +
Environment).  In these cases switch to CONFIG_SPL_STACK_R.  In other
cases we had simply been setting CONFIG_SPL_STACK into SRAM.  In these
cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also
in SRAM) so drop those lines.

a6b541b090 TI ARMv7: Don't use GD before crt0.S has set it
Prior to this change we set the gd pointer early so that we can store
data in it.  This becomes problematic for DM changes as well as being
odd in general.  Re-work the code paths so that we don't need to set the

In order to do this we do need to move certain calls from s_init into
spl_board_init(), mainly preloader_console_init and
save_omap_boot_params.

a0a37183bd ARM: omap: merge GPMC initialization code for all platform
GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
 - parallel NOR flash
 - parallel NAND flash
 - OneNand flash
 - SDR RAM
 - Ethernet Devices like LAN9220

Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.

Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c

However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
 AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
 OMAP3:  arch/arm/include/asm/arch-omap3/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap4/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap5/mem.h

Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization
 CONFIG_NAND:    initialize GPMC for NAND device
 CONFIG_NOR:     initialize GPMC for NOR device
 CONFIG_ONENAND: initialize GPMC for ONENAND device

a88e55c4c6 ARM: OMAP: replace custom sr32() by standard I/O accessors
Replace the custom bit manipulation function sr32() by standard I/O
accessors.  A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:

	6.5.7 Bitwise shift operators
	...
        If the value of the right operand is negative or is greater
        than or equal to the width of the promoted left operand, the
        behavior is undefined.

4e4685027c ARM: OMAP: hide custom bit manipulation function sr32()
The only remaining user of the custom bit manipulation function sr32()
is arch/arm/cpu/armv7/omap3/clock.c, so  make it a static function in
that file to prepare complete removal.
