[U-Boot] [PATCH 05/10] soc: ti: pruss: Add support for am57xx

[Greg Leonberg]

The KConfig file was updated to indicate support for am57xx SoCs.

Logic was added to the pruss driver to enable the clock for am57xx pruss
during the driver probe function. 

This patch depends on patches 0001 and 0004 of this patch series.
