[PATCH v2 0/5] Allow falcon boot from A-core SPL on K3 devices

[Anshul Dalal]

Hi all,

With the addition of secure falcon mode from my last few series[1], this series
now adds support for the same to TI's K3 devices and documents the feature
taking AM62x EVM as an example.

The patch [5/5] (doc: develop: falcon: document unsetting CMD_BOOTx) of the
series is a workaround for now since we first need to refactor out the usage of
CMD_BOOTI/CMD_BOOTZ options from the SPL boot flow[2].

I will be working on a respin of my older series[3] addressing the same but for
now the workaround of disabling respective CMD_BOOTx option works well enough.
With that in place we should be able to revert the patch [5/5].

Regards,
Anshul
