Enable RAM Scrambling on sama5d3 - OCMS

Wed Jul 01, 2020 6:53 pm

Hi,

Based on [the datasheet][/http://ww1.microchip.com/downloads/en/D ... 41.1365058] one can enable/disable the on-board RAM scrambling.

I am thinking about adding support for this via the at91bootstrap e.g. with dedicated configuration items.
E.g.

Code: Select all

CONFIG_OCMS
CONFIG_OCMS_KEY1
CONFIG_OCMS_KEY2

Would this be something interesting for the community?

If yes I will prepare a PR on GitHub.
