5 This README is about U-Boot support for SAMSUNG's ARM Cortex-A8 based S5PC1xx
6 family of SoCs (S5PC100 [1] and S5PC110).

15 While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
16 with -march=armv5 to allow more compilers to work. For U-Boot code this has
17 no performance impact.
