[U-Boot] [PATCH 4/8] Tegra124: Add CPU (armv7) files
Tom Warren
twarren.nvidia at gmail.com
Tue Oct 8 00:42:54 CEST 2013
These files are for code that runs on the CPU (A15)
on T124 boards. At this time, there is no A15-specific
code here. The warmboot/LP0 files aren't included as
that code hasn't been ported yet.
