The new MPC8360EMDS board changes the oscillator to 33.33MHz
in order to support QE 500MHz since 2008.

4. Compilation
MPC8360EMDS shipped with 33.33MHz or 66MHz oscillator(check U41 chip).
Assuming you're using BASH shell:
export CROSS_COMPILE=your-cross-compile-prefix
cd u-boot
make distclean
make MPC8360EMDS_config
make MPC8360EMDS_XX_config
make
MPC8360 support PCI in host and slave mode.
MPC8360EMDS support ATM, PCI in host and slave mode.
To make u-boot support ATM :
1) Make MPC8360EMDS_XX_ATM_config
To make u-boot support PCI host 66M :
1) DIP SW support PCI mode as described in Section 1.1.
2) Make MPC8360EMDS_HOST_66_config
2) Make MPC8360EMDS_XX_HOST_66_config
To make u-boot support PCI host 33M :
1) DIP SW setting is similar as Section 1.1, except for SW3[4] is 1
2) Make MPC8360EMDS_HOST_33_config
2) Make MPC8360EMDS_XX_HOST_33_config
To make u-boot support PCI slave 66M :
1) DIP SW setting is similar as Section 1.1, except for SW9[3] is 1
2) Make MPC8360EMDS_SLAVE_config
2) Make MPC8360EMDS_XX_SLAVE_config
(where XX is:
33 - 33.33MHz oscillator
66 - 66MHz oscillator)
