CFG_WITH_SOFTWARE_PRNG=y was added as an OPTEE argument to workaround
some bugs related to TRNG which have been fixed now[1]. Therefore this
patch drops the redundant argument from the documentation.

This series adds PCIe endpoint boot support for the TI J784S4 SoC.
Series is based on commit f9ffeec4bdc ("board: toradex: Make A53 get RAM
size from DT in K3 boards") of the master branch of U-Boot.

Typically we do not enable these configs by default but would still like to
have the option to start building them in our default build flow for
testing. Also there is the added advantage of users being able to see what
is needed in case they choose to enable these features.
