Hi All,
I have a Freescale MPC8313 customized board and want to confiugre
TSEC1 to SGMII. Would you please help me for this question,
1). Is it possible for MPC8313 TSEC1 connect to Ethernet Switch by
SGMII (without phy), like below diagram.
[MPC8313 TSEC1] SGMII [Ethernet Switch]
2).

Hi ALL,
I have build an embedded Linux system and rootfs is a ramdisk. Ramdisk
rootfs resides in memory so modify files is non-effective after a
reboot. Some directories in rootfs, like /etc, /usr, ... are contain
many application configuration files and I want to mount it to jffs2

It's seems a RAM initialize problem. Try to use ICE or your bootloader
to test initialized RAM wirh write/read operation.
Ex, use mtest in uboot to check memory. For ICE, it should be an
detailed memory test function like hardware diagnostic.

The kerne source I used now is 2.6.23 with MPC8313-erdb pached. I
think I should port 2.6.28 gpio function back to 2.6.23. Is it a
common way to implement it in the kernel I used or I should port
MPC8313-erdb pached to 2.6.28 opposite?

Thanks, got it. BTW, how to trigger GPIO level in user space
application? I also found arch/powerpc/platforms/52xx/mpc52xx_gpio.c
is a good example. Any reply is appreciate.

Hi All:
Is there a alreday written GPIO dirver or example for
MPC8313/similar ppc platform. It looks like many people need GPIO
dirver to control LED, etc... I think is it possible to write a
general gpio driver for all ppc platform and only need to modify gpio
iomap information of dtb file.

Hi all,
I am working in customized Freescale MPC8313 board. There are two
PCI devices (Broadcom Switch) in PCI bus.
Each PCI device has its configuration space. It contains
vendor/product ID (RO)..., and important information, likes BARs
(Base Address), INT line and IRQ(RW). These resources
