Hello Again Everyone!
The am625-lp-sk is a variant of the am625-sk showcasing the low-power
features of the am625 SoC Family. Because it's essentially a board and
package spin of the am625-sk I've inherited the am625 configuration and
overridden what was needed.
This is a new spin of Nitin's original work which has been updated
significantly since October 2023
https://lore.kernel.org/u-boot/20231030110138.1347603-1-n-yadav@ti.com/
For those of us interested here is proof of life using buildroot:
https://paste.sr.ht/~bryanb/40f7787f7760bee383aa8fbc342a29e8544dbdab
This also works around a buildman issue not following #include
directives. To get around this I've redefined the variables it's looking
for inside the lp-sk defconfig to keep it happy for now. I made a pull
request on github and everything seems like it's happy

The am62x-lp-sk is a package and reference board spin of the am62x-sk to
showcase the low-power features of the am62x SoC family. Because it so
closely resembles the am62x-sk board, use the preprocessor to inherit
its configuration making the needed changes for this board where
necessary.

This series was plucked out from the larger series [1] that did some
templating reformatting and also enabled OF_UPSTREAM for J721E. The
former has been kept aside till all the platforms affected have moved to
using OF_UPSTREAM to have less conflicts while merging.
Patches split J721E EVM and J721E SK to using separate builds, as well
as enable OF_UPSTREAM for both the platforms.

The series introduces device tree and config changes and AM65x
to enable ICSSG driver. The series also enables SPL_LOAD_FIT_APPLY_OVERLAY
for AM65x in order to load overlay over spl.
The ICSSG2 node is added in device tree overlay so that it remains in
sync with linux kernel.
This series has been tested on AM65x SR2.0, and the ICSSG interface is
able to ping / dhcp and boot kernel using tftp in uboot.
The users need to set env variables fw_storage_interface, fw_dev_part,
fw_ubi_mtdpart, fw_ubi_volume to indicate which storage medium and
partition they want to use to load firmware files from. By default the env
fw_storage_interface=mmc and fw_dev_part=1:2 but users can modify these
envs as per their requirements.
When ICSSG driver is enabled (CONFIG_TI_ICSSG_PRUETH=y) set
storage_interface and fw_dev_part env variables.
These variables need be set appropriately in order to load differnet
ICSSG firmwares needed for ICSSG driver. By default the storage
interface is mmc and the partition is 1:2. User can modify this based on
their needs.

EEPROM detection logic in ti_i2c_eeprom_get() involves reading
the total size and the 1-byte size with an offset 1. The commit
9f393a2d7af8 ("board: ti: common: board_detect: Fix EEPROM read
quirk for 2-byte") that attempts to fix this uses a wrong pointer to
compare.
The value with one offset is read into offset_test, but the pointer
used to match was still ep, resulting in an invalid comparison of the
values. The intent is to identify bad 2-byte addressing eeproms that
get stuck on the successive reads.
