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
|
||||
=====
|
||||
|
||||

||||

||||

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