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.

There are no SPI peripherals in neither the IGEPv2 board nor the IGEP COM

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.

Use upstream device tree files and bindings. To do so:
- imply (enable) OF_UPSTREAM option for E850-96 target
- point DEFAULT_DEVICE_TREE in E850-96 config to upstream dts
- remove now not needed local dts files, binding docs and headers
- update MAINTAINERS and board/samsung/e850-96/MAINTAINERS
correspondingly
Upstream device tree files for Exynos850 SoC and E850-96 board are
pretty much the same as local (removed) ones, so the conversion is
rather straightforward and painless in this case. The appended dts file
(arch/arm/dts/exynos850-e850-96-u-boot.dtsi) stays unchanged.
The only remaining local dt-bindings doc for E850-96 board is
exynos-pmu.yaml. It wasn't removed as it's quite different from Linux
kernel version. Particularly U-Boot local version of exynos-pmu.yaml
describes "samsung,uart-debug-1" property, which is not present in Linux
kernel binding. Later it might be upstreamed to Linux kernel, and once
it's done the U-Boot exynos-pmu.yaml binding can be removed.
No functional change.

Instead of displaying what looks like an error message if a
gpio-reset dt prop is missing for a TPM display a warning that
having a gpio reset on a TPM should not be used for a secure production
device.
TCG TIS spec [1] says:
"The TPM_Init (LRESET#/SPI_RST#) signal MUST be connected to the
platform CPU Reset signal such that it complies with the requirements
specified in section 1.2.7 HOST Platform Reset in the PC Client
Implementation Specification for Conventional BIOS."
The reasoning is that you should not be able to toggle a GPIO and reset
the TPM without resetting the CPU as well because if an attacker can
break into your OS via an OS level security flaw they can then reset the
TPM via GPIO and replay the measurements required to unseal keys
that you have otherwise protected.
Additionally restructure the code for improved readability allowing for
removal of the init label.

- board with no reset gpio
u-boot=> tpm init && tpm info
