Both 'loadfit' and 'mmcloados' start with a call to 'args_mmc' so this
can be factored out to before eithers only call site. This also allows us
to remove that call from 'loadfit', which should not have been calling it
anyway as that command should not be MMC specific. Without the call to
'args_mmc' the command 'loadfit' becomes just a call to 'run_fit' so
remove the indirection and call 'run_fit' directly, this removes the need
for 'loadfit' command (which was misnamed anyway). Drop it.

On K3 systems U-Boot runs on both an R5 and a large ARM cores (usually
A53 or A72). The large ARMs are coherent with the DMA controllers and
the SYSFW that perform authentication. And previously the R5 core did
not enable caches. Now that R5 does enable caching we need to be sure
to clean out any of the image that may still only be in cache before we
read it using external DMA for authentication.
Although not expected to happen, it may be possible that the data was
read back into cache after the flush but before the external operation,
in this case we must invalidate our stale local cached version.

The TI J721E EVM system on module (SOM), the common processor board, and
the associated daughtercards have on-board I2C-based EEPROMs containing
board config data. Use the board detection infrastructure to do the
following:
1) Parse the J721E SOM EEPROM and populate items like board name, board
HW and SW revision as well as board serial number into the TI common
EEPROM data structure residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing associated I2C
addresses used for on-board EEPROMs containing daughter card-specific
data. If such a card is found, parse the EEPROM data such as for
additional Ethernet MAC addresses and populate those into U-Boot
accordingly
3) Dynamically apply daughter card DTB overlays to the U-Boot (proper)
DTB during SPL execution
4) Dynamically create an U-Boot ENV variable called name_overlays
during U-Boot execution containing a list of daugherboard-specific
DTB overlays based on daughercards found to be used during Kernel
boot.
This patch adds support for the J721E system on module boards containing
the actual SoC ("J721EX-PM2-SOM", accessed via CONFIG_EEPROM_CHIP_ADDRESS),
the common processor board ("J7X-BASE-CPB"), the Quad-Port Ethernet
Expansion Board ("J7X-VSC8514-ETH"), the infotainment board

processor (DSP), quad-core embedded vision engine (EVE), Arm Cortex-M4
processors, dual programmable realtime unit industrial control
subsystems and more. The board features 1GB DDR3L, USB3.0 Type-C, USB
HS Type-A, microHDMI, 16GB eMMC flash, 1G Ethernet, 802.11ac 2/5GHz,
Bluetooth, and BeagleBone expansion headers.
For more information, refer to:

The corresponding patch against the mainline linux kernel can be found
at: https://patchwork.kernel.org/patch/11254903/
This patch introduces the BeagleBone AI device tree.
Note that the device use the "ti,tpd12s016" component which is software
compatible with "ti,tpd12s015". Thus we only use the latter driver.

BeagleBoard.org BeagleBone AI rev A1 does not include a board
identifier I2C EEPROM due to a design oversight. These boards have
been put into production and are generally available now.
The board identifier information, however, has been included in the
second eMMC linear boot partition (/dev/mmcblk1boot1).
This patch works by:
* First, looking for a board identifier I2C EEPROM and if not found,
* Then seeing if the boot mode matches BeagleBone AI with eMMC in the
boot chain to make sure we don't enable eMMC pinmuxes on boards
that don't support it, and
* Finally, initializes the eMMC pins and reading the header.

Add Support for writing to PHY registers for J721e. There are number of
differences between the J721e 8 bit PHY, J721e 4 bit PHY and AM654 PHY.
Create a driver_data structure with an ops and flags field and use the
flags field to indicate these differences. The differences are as
follows:
1. The J721e 4 bit instance PHY does not have a DLL. Introduce a
DLL_PRESENT flag to make sure that DLL related registers are accessed
only where they are present. Also add a separate set_ios_post()
callback.
2. The J721e 8 bit instance is not muxed with anything else inside the
SoC and hence the IOMUX_ENABLE filed does not exist. Add a flag which is
used to indicate the presence of this field.
3. The register field used to select DLL frequency is 3 bit wide in
J721e as compared to 2 bits in AM65x. Add another flag that
distinguishes these fields.
4. The strobe select field is 8 bit wide as compared to 4 bit wide for
AM65x. Add yet another flag to indicate this difference. Strobe select
is used only for HS400 speed mode, support for which has not been added
in AM65x.
