[U-Boot] [PATCH v4 13/13] tegra20: Remove armv4t build flags

Allen Martin amartin at nvidia.com
Fri Jun 22 02:00:47 CEST 2012


These flags were necessary when building tegra20 as a single binary
that supported ARM7TDMI and Cortex A9.  Now that the ARM7TDMI support
is split into a separate SPL, this is no longer necessary.
