The AM62x uses the DA8XX (DaVinci) GPIO controller. Enable
CONFIG_DA8XX_GPIO to support GPIO access from the Cortex-A53.
Also enable the 'gpio' command to allow users to interact
with GPIOs from the U-Boot shell.

This enables the 'rproc' command, allowing users to

images.
Useful for systems with auxiliary cores, such as the M4 core
in the AM62x soc.

Wadim Egorov <w.egorov@phytec.de> says:
Our SoMs are available in multiple configurations, managed via device
tree overlays. To determine the specific variant in use, we read the
EEPROM and apply the appropriate overlays during boot to the device tree
used by the OS.
Apply overlays for phyCORE-AM62x and phyCORE-AM64x SoMs.
Future K3 SoMs will be able to reuse this logic and overlays.

This patch stack extends the phyCORE-AM62x/AM64x U-Boot by following boot
sources:
- Load U-Boot with USB DFU
- Load a Linux and initramfs from OSPI/QSPI NOR flash
- Load a Linux and rootfs from Network
Moreover, it adds required changes to the environment to boot an A/B
system with RAUC and includes some minor fixes.
Commit 371b379edb ("configs: Make USB_GADGET_MANUFACTURER
consistent over all PHYTEC boards") made the USB_GADGET_MANUFACTURER
value consistent over all PHYTEC boards.

as well.

Merge the am62x_a53_usbdfu.config into the phyCORE-AM62x A53 defconfig to

This config was made with the following command:

However, CONFIG_USB_GADGET_MANUFACTURER was not merged to keep Phytec

Make the raw-mode options depend on SPL_SYS_MMCSD_RAW_MODE in a more
direct way. This makes it easier to understand the options with
'make menuconfig'.
There are three different ways of specifying the offset:
- sector offset
- partition number
- partition type
So make these a choice, so it is more obvious what is going on.
Update existing boards to enable SPL_SYS_MMCSD_RAW_MODE where needed.

The help for CONFIG_MTD explains that it needs to be enabled for various
things like NAND, etc to be available. It however then doesn't enforce
this dependency and so if you have none of these systems present you
still need to disable a number of options. Fix this by making places
that select/imply one type of flash, but did not do the same, also do
this for "MTD". Make boards which hadn't been enabling MTD already but
need it now, do so. In a few places, disable CONFIG_CMD_MTDPARTS as it
wasn't previously enabled but was now being implied.
