Implement an early console functionality in SPL that can be used before
the main console is being brought up. This helps in situations where the
main console is dependent on System Firmware (SYSFW) being up and running,
which is usually not the case during the very early stages of boot. Using
this early console functionality will allow for an alternate serial port
to be used to support things like UART-based boot and early diagnostic
messages until the main console is ready to get activated.

The memory allocated to store the FIT image containing SYSFW and board
configuration data is statically defined to the largest size expected.
This was 269000 bytes but now needs to be grown to 276000 to make room
for the signatures attached to the board configuration data on High
Security devices.

The J721E SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable lower system costs
of automotive applications such as infotainment, cluster, premium
Audio, Gateway, industrial and a range of broad market applications.
This SoC is designed around reducing the system cost by eliminating
the need of an external system MCU and is targeted towards ASIL-B/C
certification/requirements in addition to allowing complex software
and system use-cases.
Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, three clusters of lockstep
capable dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA),
C7x floating point Vector DSP, Two C66x floating point DSPs.
* 3D GPU PowerVR Rogue 8XE GE8430
* Vision Processing Accelerator (VPAC) with image signal processor and Depth
and Motion Processing Accelerator (DMPAC)
* Two Gigabit Industrial Communication Subsystems (ICSSG), each with dual
PRUs and dual RTUs
* Two CSI2.0 4L RX plus one CSI2.0 4L TX, one eDP/DP, One DSI Tx, and
up to two DPI interfaces.
* Integrated Ethernet switch supporting up to a total of 8 external ports in
addition to legacy Ethernet switch of up to 2 ports.
* System MMU (SMMU) Version 3.0 and advanced virtualisation
capabilities.
* Upto 4 PCIe-GEN3 controllers, 2 USB3.0 Dual-role device subsystems,
16 MCANs, 12 McASP, eMMC and SD, UFS, OSPI/HyperBus memory controller, QSPI,
I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Two hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
management.
* Configurable L3 Cache and IO-coherent architecture with high data throughput
capable distributed DMA architecture under NAVSS
* Centralized System Controller for Security, Power, and Resource
Management (DMSC)

Introduce a framework that allows loading the System Firmware (SYSFW)
binary as well as the associated configuration data from an image tree
blob named "sysfw.itb" from an FS-based MMC boot media or from an MMC
RAW mode partition or sector.
To simplify the handling of and loading from the different boot media
we tap into the existing U-Boot SPL framework usually used for loading
U-Boot by building on an earlier commit that exposes some of that
functionality.
Note that this initial implementation only supports FS and RAW-based
eMMC/SD card boot.

Considering the boot time requirements, Cortex-A core
should be able to start immediately after SPL on R5.
Add support for the same.

AM654 allows for booting from primary or backup boot media.
Both media can be chosen individually based on switch settings.
ROM looks for a valid image in primary boot media, if not found
then looks in backup boot media. In order to pass this boot media
information to boot loader, ROM stores a value at a particular
address. Add support for reading this information and determining
the boot media correctly.
