Enable configs for building multiple dtbs into a single fit image and load the
appropriate dtb for next stage. Add k3-am69-sk dtb along with the evm dtb. This
facilitates the use of common defconfig for both EVM and SK.

The board name is programmed in the EEPROM. Add support for board
detection and choose the right dtb based on the board name read
from EEPROM.
The J784S4/AM69 has two platforms naming J784S4-EVM and AM69-SK. The
J784S4 has EEPROM populated at 0x50. AM69 SK has EEPROM
populated at next address 0x51. So start looking for TI specific EEPROM
at 0x50, if not found look for EEPROM at 0x51.

The u-boot ums command models the EVM as a card reader and shows the SD
Card latched on the evm as a memory device in the host PC. The Type - C
dual role port should be used for this functionality. This helps in
automating the linux debugging process.

Add new R5 defconfig for USB MSC boot support based on usbdfu_defconfig
and add USB host and storage options A53 defconfig.
USB Host boot is supported only from USB0 port. By default USB0
is configured in peripheral mode to support DFU. Inorder to support
USB Host boot, "dr_mode" property needs to be changed from "peripheral"
to "host" in the device tree.

The default U-Boot environment variables and design are all set up for
both the MAIN R5FSS clusters to be in Split-mode.
The mode for both the R5 clusters is defaulted to cluster mode. This
throws the following failure messages when early-booting the cores using
default env variables.
Error log:
k3_r5f_rproc r5f@5d00000: Invalid op: Trying to start secondary core 7 in lockstep mode
Load Remote Processor 3 with data@addr=0x82000000 322476 bytes: Failed!
Fix this by updating both the clusters to Split-mode in the u-boot specific
dtsi, to avoid this sync overrides in the future.

After performing DFS on A72, the clk-k3 driver causes the reboot to fail
due to fault clock re-initialization
The clk-k3.c driver performs PLL setup based on the difference between
the requested clock rate and current clock rate. If the difference is
found to be more that 50%, in that case it recurses to the clock's parent
for changing its frequency and setting up the PLL. If the difference is
found to be less than that, it assumes that it is a rounding error in the
divider and tries to accommodate for that without touching the parent
clocks.
So, 5% to 50% difference, it assumes it to be a rounding error. From 50%
difference onward it treats it as a HSDIV+PLL configuration case and
sets everything correctly.
So when a fresh boot happens, the A72 clock frequency is found to be at
19.2MHz, which is way less than 2GHz and hence it crosses 50% barrier and
gets properly setup. But when we change the A72 frequency to 1.5 GHz
through DFS, the difference is only of 25% (<50%). So, when we do a
reboot, it doesn't configure the parent clocks and PLLs, it just tries to
make the value close to 2GHz, but that doesn't work.
So, reduce the threshold from 50% to 12.5%, to reconfigure the clocks
correctly at reboot, allowing to boot up after a DFS operation.
Also, check if the parent pll rate is indeed set to target rate, if not
fallback adjusting dividers to get within 5% of requested rate.
This is required to set correct rate for DDR PLLs on AM62A resulting in
lower DDR bandwidth when measured with lmbench (bw_mem)
