eaf6ea6a1d Migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h
- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
  pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
  set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
  GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
  board config header files.

4c97c8cd42 powerpc: Switch to using CONFIG_SYS_INIT_SP_OFFSET from CONFIG_SYS_GBL_DATA_OFFSET
In the places where PowerPC references CONFIG_SYS_GBL_DATA_OFFSET it
does so as (CONFIG_SYS_INIT_RAM_ADDR + CONFIG_SYS_GBL_DATA_OFFSET).  And
it defines CONFIG_SYS_GBL_DATA_OFFSET in the same manner that other
architectures define CONFIG_SYS_INIT_SP_OFFSET. Other architectures
define CONFIG_SYS_INIT_SP_ADDR as (CONFIG_SYS_INIT_RAM_ADDR +
CONFIG_SYS_INIT_SP_OFFSET) typically.  Rename things within PowerPC for
consistency with other architectures.

5d6a64f71d Remove CONFIG_HAS_ETH0 et al symbols
This converts removes the following symbols:
   CONFIG_HAS_ETH0
   CONFIG_HAS_ETH1
   CONFIG_HAS_ETH2
   CONFIG_HAS_ETH3

This is because at this point, only the ids8313 platform was using the
code which was controlled by these symbols.  In turn, this code already
performs error checking on being able to perform the device tree fixup.
Rather than convert these to Kconfig for a single platform, update the
code to not need these checks and remove them from all the platforms
they were unused on.

3847ba94f0 Finish converting CONFIG_WATCHDOG, HW_WATCHDOG and WDT to Kconfig
Because of how these symbols work, and the remaining board config.h file
uses, we need to do these at the same time.  In some cases we just get
to move rather directly to the defconfigs.  A few cases require manual
intervention.

For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the
target, given how it's implemented.

For the cases of m53menlo, dh_imx6, display5, and display5_factory we
disable SPL watchdog support as the particular combination of options
they want would require either more symbols or enabling SPL_DM.

Also we want to have a CONFIG_I2C for U-Boot proper just like we have
CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules.

Rename this symbol so it is clear it is going away.

- On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR
  for the pre-main-U-Boot environment location.
- On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
  rather it being non-zero, as it will now be zero by default.
- Rework the env_offset absolute in env/embedded.o to not use

  ENV_IS_IN_FLASH.
- Migrate all platforms.

We have CONFIG_ENV_SIZE_IS_REDUND but don't really use it.  We have one
board where we can simply multiple CONFIG_ENV_SIZE by two for the same

this is for where env_internal.h checks for if we should set
ENV_IS_EMBEDDED.  This seems like the most likely use, historically, of
the variable, but it was not used.  Add logic to check for this now.

0f06f57c28 mpc83xx: Replace CONFIG_83XX_CLKIN in calculations
CONFIG_SYS_CLK_FREQ is the standard way to set the system clock
frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose.
Hence, the obvious way is to replace CONFIG_83XX_CLKIN with
CONFIG_SYS_CLK_FREQ.

A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing
CONFIG_SYS_NS16550_CLK. This makes it harder to replace
CONFIG_83XX_CLKIN.

But the value of the multiplicator can be read from the SPMR register.

Hence, replace the static calculations with a call to a new get_bus_freq
function, as other architectures do.
