I am working in a project where we are considering using U-Boot as a

The chip is currently not supported by U-Boot.
The processor will not be running linux.

I'm porting u-boot to my board. But i do not know how to start. My board

So I am having another issue probably more related to computer science
fundamentals.

I define boot_device in arch/arm/include/asm/arch-mx5/sys_proto.h like this…
Now, boot_dev returns the correct value in checkboard(), but r
Update: my board_late_init() function wasn’t working because I defined

Thank you for the responses guys, much appreciated. We will look into using
the latest release.
Another question...
Can we still use setenv() in the board file?

but it doesn't seem to work in new u-boot

Hi,
I'm attempting to port u-boot for NS7520 (arm7tdmi). My idea was to first
revive the port of NS9750 (removed in
commit4cfc611b4a4ce009cfad46804bec2a1caad8e329) and then rename and
configure it for NS7520 which is quite similar. But I've kind of hit a wall,
that I don't understand.

Hi,
I am trying to port u-boot for MPC8280 by taking reference MPC8260ADS,
but its not booting,
u-boot Version u-boot-1.3.1
ARCH = PPC 82xx
Processor = MPC8280
Bootflash = AM29LV040B (512kb) mirror bit
sdram = 512MB
I modified MPC8260ADS with CPU clock frequency 100MHz,
I am trying to port u-boot to multiple soc/boards from an arm vendor.
I would appreciate any input on the following approach
1)The controller instance on various SOC are the same with minor
differences in the fifo size, gpios, clocks.
2)In order to help the porting effort, my idea is to add soc
