bc74163a46 board: ti: am65x: Add UART boot procedure in README
am65x ROM support booting over UART. And U-Boot built for am65x EVM
supports UART boot as well. Add the UART boot procedure into the README
also providing a corresponding example command sequence for execution
on a host PC.

03facc7271 board: ti: am654: Use EEPROM-based board detection
The TI AM654x EVM base board and the associated daughtercards have on-
board I2C-based EEPROMs containing board configuration data. Use the
board detection infrastructure introduced earlier to do the following:

1) Parse the AM654x EVM base board EEPROM and populate items like board
   name and MAC addresses into the TI common EEPROM data structure
   residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
   presence signals via an I2C-based GPIO expander. Then, if such a
   card is found, parse the data such as additional Ethernet MAC
   addresses from its on-board EEPROM and populate into U-Boot
   accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
   containing a list of daugherboard-specific DTB overlays based on
   daughercards found.

This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
as well as for the IDK ("AM6-IDKAPPEVM"), OLDI LCD ("OLDI-LCD1EVM")
PCIe/USB3.0 ("SER-PCIEUSBEVM"), 2 Lane PCIe/USB2.0 ("SER-PCIE2LEVM"),
and general purpuse ("AM6-GPAPPEVM") daughtercards.

b5d2e2980b am65x: README: Add eMMC layout and flash instructions
Add instructions for flashing boot images to the eMMC with a
layout of the address where each image needs to be flashed.

Also add instructions to flash filesystem partition in user
partition and boot kernel from the rootfs.

c222e3d927 armV7R: K3: am654: Load SYSFW binary and config from boot media
Use the System Firmware (SYSFW) loader framework to load and start
the SYSFW as part of the AM654 early initialization sequence. While
at it also initialize the WKUP_UART0 pinmux as it is used by SYSFW
to print diagnostic messages.
