* Support for armv7-m_dcache control via parameter
The FORCE_F7_DCACHE parameter can be set to
0 - (default) if Eratta exits turn dcache off else leave it on
1 - Force it off
2 - Force it on
At boot the system will disable the d-cache if the silicon
has the 1259864 Data corruption in a sequence of Write-Through
stores and loads eratta.
Post nsh script execution the FORCE_F7_DCACHE paramater
will be used to set the d-cache to the state indicated
above.
