commit fd3ecda38fe0cb713d167b5477d25f6b350f0514 upstream.
The OCRAM ECC is always enabled either by the BootROM or by the Secure Device
Manager (SDM) during a power-on reset on SoCFPGA.
However, during a warm reset, the OCRAM content is retained to preserve data,
while the control and status registers are reset to their default values. As
a result, ECC must be explicitly re-enabled after a warm reset.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
