Summary
=======
This README is about U-Boot support for SAMSUNG's ARM Cortex-A8 based S5PC1xx
family of SoCs (S5PC100 [1] and S5PC110).
Currently the following board is supported:
* SMDKC100 [2]
Toolchain
=========
While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
with -march=armv5 to allow more compilers to work. For U-Boot code this has
no performance impact.
Build
=====
* SMDKC100
make smdkc100_config

Interfaces
==========

To check SoC:
if (cpu_is_s5pc100())
printf("cpu is s5pc100\n");
or
if (cpu_is_s5pc110())
printf("cpu is s5pc110\n");
