This series contains improvements for the 'eeprom' command:
- refactors
- fixes
- improvements
- ability to use driver model EEPROMs (uclass UCLASS_I2C_EEPROM)
- more flexible EEPROM layout support
It should not cause any behavior change for any existing board.
This series is a dependency for some DDR issue fixes for Turris Omnia.
I will be sending that one separately.

- there is a failure for
test.py for sandbox sandbox_clang
but it seems unrelated to these changes
Extend the 'eeprom' command to allow accessing EEPROMs probed via
driver model, uclass UCLASS_I2C_EEPROM.
When the CONFIG_I2C_EEPROM config option is enabled (and so the
i2c-eeprom driver is built), the 'eeprom' command now accepts driver
model device name as EEPROM specifier for the 'eeprom' command, in
addition to the legacy [[bus] devaddr] specifier.
Moreover if no device specifier is given, then the first
UCLASS_I2C_EEPROM device is used, if found.

In preparation for allowing to access eeprom by driver-model device

Hello,
I noticed that the IGEPv2 board did not boot anymore with mainline U-Boot.
This was caused by a driver change to allocate its platform data before
relocation and U-Boot not having enough pre-relocation heap size for this.
This series fixes this issue and also makes the board support more modern,
by enabling DM for SPL and migrating the IGEP boards to use upstream DTBs.
Enable OF_UPSTREAM to use upstream DT and add a ti/omap/ prefix to the
DEFAULT_DEVICE_TREE config option.
That way, a DTS from the upstream dts/upstream/src/ directory is used
instead of the arch/$(ARCH)/dts/ directory. These in turn are removed.

The IGEPv2 board boot started to fail since the commit afd4f15a39 ("spi:
omap3_spi: Read platform data in ofdata_to_platdata()"). Because this made
the OMAP3 SPI controller driver to allocate its platform data before doing
a relocation, but the igep0x00 config sets this pool size to just 1 KiB.
Increase the pre-relocation malloc heap size to 16 KiB, as is set by other
OMAP3 boards. This not only restores booting but also makes it consistent.
Leave the SPL pool size to the previous 1 KiB size since 16 KiB may not be
a possible size in that constrained environment and is also the value that
is set by other OMAP3 boards.
