Update MPU frequencies and voltages as per the latest
DM[1] dated: OCT 2011 Revised APRIL 2016, Section 5.4.
Below is the consolidated data:
MPU values for PG 2.0 and later(Package ZCZ and ZCE):
-------------------------------------------------------
| | ZCZ | ZCE |
|-------------------------------------------------------|
| | VDD[V] | ARM [MHz] | VDD[V] | ARM [MHz] |
|-------|----------|------------|----------|------------|
| NITRO | 1.325 | 1000 | NA | NA |
|-------|----------|------------|----------|------------|
| TURBO | 1.26 | 800 | NA | NA |
|-------|----------|------------|----------|------------|
|OPP120 | 1.20 | 720 | NA | NA |
|-------|----------|------------|----------|------------|
|OPP100 | 1.10 | 600 | 1.10 | 600 |
|-------|----------|------------|----------|------------|
| OPP50 | 0.95 | 300 | 0.95 | 300 |
-------------------------------------------------------
There is no eFuse blown on PG1.0 Silicons due to which there is
no way to detect the maximum frequencies supported. So default
to OPP100 for which both frequency and voltages are common on both
the packages.

Up till this commit passing NULL as input parameter was allowed, but not
handled properly.
When one passed NULL to one of this function parameters, the code was
executed causing data abort.
However, what is more interesting, the abort was not caught because of code
execution in HYP mode with masked CPSR A bit ("Imprecise Data Abort mask bit).
The TI's AM57xx SoC switch to HYP mode with A bit masked in lowlevel_init.S
due to SMC call. Such operation (by default) is performed in SoC ROM code.
The problem would pop up when one:
- Switch back to SVC mode after disabling LPAE support
- Somebody enables A bit (by executing cpsie a asm instruction)
and then the previously described exception would be caught.

When TI_SECURE_DEV_PKG is not defined we warn that the file '*_HS' was
not generated but generate an unsigned one anyway, first fix this
warning to say that it was generated but not secured.
When the user then exports TI_SECURE_DEV_PKG after getting this warning,
and tries to re-build, 'make' will detect the build artifacts as
unchanged and so assume they do not need to be re-generated. This causes
it to fail to sign the files and it will pack unsigned files into the
final image, even though TI_SECURE_DEV_PKG is now correctly defined and
working.
Fix this by using FORCE on the targets causes them to be re-run even if
the dependent files have not changed.
This then causes another issue. We currently rename the signed dtb files
to overwrite the non-signed ones. We do this so the 'mkimage' tool gives
the packaged dtb sections the correct name. If we do not rename the files
then SPL will not find them during boot.
Fix this by renaming the dtb files by appending _HS to the end of the
filename, after the ".dtb", this causes them to still be named correctly
in the FIT blob.

This patch adds support to update the device-tree blob to adjust the
DSP and IVA DPLL clocks pertinent to the selected OPP choice, with
the default being OPP_NOM. The voltage settings are done in u-boot,
but the actual clock configuration itself is done in kernel because
of the following reasons:
1. SoC definition constraints us to NOT to do dynamic voltage
scaling ever after the initial avs0 setting in bootloader
- so the voltage must be set in bootloader.
2. The voltage level must be set even if the IP blocks like
GPU/DSP are unused.
3. The IVA, GPU and DSP DPLLs are not essential for u-boot functionality,
and similar DPLL clock configuration code has been cleaned up in
v2014.10 u-boot release. See commit, 02c41535b6 ("ARM: OMAP4/5:
Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL").
The non-essential DPLLs are configured within the kernel during
the clock init step when parsing the device tree and creating
the clock devices. This approach meets both the u-boot and kernel
needs.

Redefine the macros used to define the voltage values and the

This is done using Kconfig macros that can be set in a defconfig

to be configured/set to a corresponding voltage value depending
on the OPP selection choice.
The Kconfig choices have been added for MPU, DSPEVE, IVA and GPU
voltage domains, with the MPU domain restricted to OPP_NOM. The
OPP_OD and OPP_HIGH options will be added when the support for
configuring the MPU clock frequency is added. The clock
configuration for other voltage domains is out of scope in
u-boot code.
The CORE voltage domain does not have separate voltage values
and efuse register offset at different OPPs, while the MPU
voltage domain only has different efuse register offsets for
different OPPs, but uses the same voltage value. Any different
choices of OPPs for voltage domains on common ganged-rails
is automatically taken care to select the corresponding

This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories. All refernces to the former locations are updated to
the current locations. For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.
