1. SoC definition constraints us to NOT to do dynamic voltage
   scaling ever after the initial avs0 setting in bootloader

2. The voltage level must be set even if the IP blocks like

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

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

Redefine the macros used to define the voltage values and the
efuse register offsets based on OPP for all the voltage domains.
This is done using Kconfig macros that can be set in a defconfig
or selected during a config step. This allows a voltage domain
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

Yann E. MORIN [Sun, 13 Nov 2016 20:59:52 +0000 (21:59 +0100)]
cmd: move CMD_PXE to Kconfig

Currently, CMD_PXE is forcibly enabled in config_distro_defaults.h, so
that general purpose distributions can rely on it being defined. This
header is included, under conditions or not, by various archs or
famillies of archs / SoCs.

However, it is very possible that boards based on those SoCs will not
have a physical ethernet connector at all, even if the have a MAC; for
example, the Nanopi Neo AIR (sunxi H3) does not. It is also possible
that network booting is absolutely not necessary for a device.

However, it is not possible to disable the PXE command, as it is
forcibly enabled and is non-configurable.

But it turns out we already have a config option to build a distro-ready
image, in the name of DISTRO_DEFAULTS.

Move CMD_PXE out of the hard-coded config_distro_defaults.h into a
Kconfig option, that gets selected by DISTRO_DEFAULTS when it is set.
