firmware is not able to set the frequency exactly to the target, the
current implementation fails if the available frequency is even 1Hz off
the target. With the change, the firmware still tries its best to set
the frequency as close as possible to the target.

ea70da142c arm: K3: Disable ROM configured firewalls
ROM configures certain firewalls based on its usage, which includes
the one in front of boot peripherals. In specific case of boot
peripherals, ROM does not open up the full address space corresponding
to the peripherals. Like in OSPI, ROM only configures the firewall region
for 32 bit address space and mark 64bit address space flash regions
as in-accessible.

When security-cfg is initialized by sysfw, all the non-configured
firewalls are kept in bypass state using a global setting. Since ROM
configured firewalls for certain peripherals, these will not be touched.
So when bootloader touches any of the address space that ROM marked as
in-accessible, system raises a firewall exception causing boot hang.

It would have been ideal if sysfw cleans up the ROM configured boot
peripheral firewalls. Given the memory overhead to store this
information provided by ROM and the boot time increase in re configuring
the firewalls, it is concluded to clean this up in bootloaders.

So disable all the firewalls that ROM doesn't open up the full address
space.

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.

95b256ec3f arm: mach-k3: security: Clean image out of cache before authentication
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.

643eb6ea07 board: ti: j721e: Use EEPROM-based board detection
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
("J7X-INFOTAN-EXP") as well as for the gateway/Ethernet switch/industrial
expansion board ("J7X-GESI-EXP").

499681e15e ti: common: board_detect: Handle EEPROM probe more gracefully
Use dm_i2c_probe() rather than i2c_get_chip() when trying to access
board-detection EEPROM devices. This has the advantage of more gracefully
handling the case when the EEPROM is not present by allowing to exit the
function early rather than failing and outputting an error message on the
I2C transactions that follow.

BeagleBoard.org BeagleBone AI is an open source hardware single board
computer based on the Texas Instruments AM5729 SoC featuring dual-core
1.5GHz Arm Cortex-A15 processor, dual-core C66 digital signal
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:
https://beaglebone.ai

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.

These are necessities for beaglebone ai boot. There is the addition of
CONFIG_SUPPORT_EMMC_CONFIG to the Kconfig file. This is present upstream
but not in 19.01 yet.
