Texas Instruments has begun enabling security settings on the SoCs it
produces to instruct ROM and TIFS to begin protecting the Security
Management Subsystem (SMS) from other binaries we load into the chip by
default.
One way ROM and TIFS do this is by enabling firewalls to protect the
OCSRAM and HSM RAM regions they're using during bootup.
The HSM RAM the wakeup SPL is in is firewalled by TIFS to protect
itself from the main domain applications. This means the 'bootindex'
value in HSM RAM, left by ROM to indicate if we're using the primary
or secondary boot-method, must be moved to OCSRAM (that TIFS has open
for us) before we make the jump to the main domain so the main domain's
bootloaders can keep access to this information.

The first AM6x device was the AM654x, but being the first we named it
just AM6, since more devices have come out with this same prefix we
should switch it to the normal convention of using the full name of the
first compatibility device the series. This makes what device we are
talking about more clear and matches all the K3 devices added since.

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.

To simplify the handling of and loading from the different boot media
