fa2f81b06f TI: Rework SRAM definitions and maximums
On all TI platforms the ROM defines a "downloaded image" area at or near
the start of SRAM which is followed by a reserved area.  As it is at
best bad form and at worst possibly harmful in corner cases to write in
this reserved area, we stop doing that by adding in the define
NON_SECURE_SRAM_IMG_END to say where the end of the downloaded image
area is and make SRAM_SCRATCH_SPACE_ADDR be one kilobyte before this.
At current we define the end of scratch space at 0x228 bytes past the
start of scratch space this this gives us a lot of room to grow.  As
these scratch uses are non-optional today, all targets are modified to
respect this boundary.

Tested on OMAP4 Pandaboard, OMAP3 Beagle xM

36080228ed ARM: DRA7: Update/Correct MPU and CORE OPP_NOM voltage values
The current OPP_NOM voltage values defined for the MPU and CORE
voltage domains are based on the initial DRA75x_74x_SR1.1_DM data
manual. As per this DM, the PMIC boot voltage can be set to either
1.10V or 1.15V for VD_MPU, and either 1.06V or 1.15V for VD_CORE.
While the current values are correct, the latter set of values
are the values that are common across all DRA75x, DRA72x SoCs and
for all current Silicon revisions. So, update both the MPU and CORE
OPP_NOM voltages to 1.15V.

The macros are also slightly reorganized so that both the MPU and
CORE voltage domain values are defined together.

93e6253d11 ARM: OMAP4/5: Centralize early clock initialization
Early clock initialization is currently done in two stages for OMAP4/5
SoCs. The first stage is the initialization of console clocks and
then we initialize basic clocks for functionality necessary for SoC
initialization and basic board functionality.

By splitting up prcm_init and centralizing this clock initialization,
we setup the code for follow on patches that can do board specific
initialization such as board detection which will depend on these
basic clocks.

As part of this change, since the early clock initialization
is centralized, we no longer need to expose the console clock
initialization.

NOTE: we change the sequence slightly by initializing console clocks
timer after the io settings are complete, but this is not expected
to have any functioanlity impact since we setup the basic IO drive
strength initialization as part of do_io_settings.

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.

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.

This patch implements correct operation of the core voltages

more than one domain shall be written only once, and with the
highest voltage of those fused in the SoC (or of those defined
in the corresponding header if fuse read is disabled or fails)
for the power rails belonging to the group.

Those regulators don't have any coupling with
what they supply, so remove the suffixes in order
to not confuse anybody.

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 */
     SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */
     SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */
     SW3.6 (SYSBOOT[13])= ON  (logic-1) /* device bus-width: 1(x16) */
     SW3.7 (SYSBOOT[14])= OFF (logic-0) /* reserved */
     SW3.8 (SYSBOOT[15])= ON  (logic-1) /* reserved */

Also, following changes are required to enable NOR Flash support in
dra7xx_evm board profile:

939911a64b armv7:TI: Add <asm/ti-common/sys_proto.h> and migrate omap_hw_init_context
The omap_hw_init_context function (and assorted helpers) is the same for
all OMAP-derived parts as when CHSETTINGS are used, that's the same and
our DDR base is also always the same.  In order to make this common we
simply need to update the names of the define for DDR address space
which is also common.

cd324a6dd2 ARM: omap5: add platform specific info for GPMC and ELM controllers
This patch moves platform specific information for GPMC and ELM controller
into separate header files, so that any derivative devices do not mess other
header files.

Platform specific information added into arch-xx/../hardware.h
 - CPU related platform specific details like base-address of GPMC and ELM

Platform specific information added into arch-xx/../mem.h
 - Generic configs for GPMC and ELM initialization.
 - Hardware parameters or constrains specific to GPMC and ELM IP like;
   number of max number of chip-selects available

omap_gpmc.h is a generic header used by OMAP NAND driver for all TI platfoms.
Hence this file should be present in generic folder instead of architecture
specific include folder.

51d192c40d mtd: nand: omap: merge duplicate GPMC data from different arch-xx headers into common omap_gpmc.h
Each SoC platform (AM33xx, OMAP3, OMAP4, OMAP5) has its own copy of GPMC related
defines and declarations scattered in SoC platform specific header files
like include/asm/arch-xx/cpu.h
However, GPMC hardware remains same across all platforms thus this patch merges
GPMC data scattered across different arch-xx specific header files into single
header file include/asm/arch/omap_gpmc.h
