Hi all, I have a Globalscale Dreamplug I wish to accomplish the following:
- Backup original uboot
- Verify original uboot
- Flash patched uboot to SPI
Any roadblocks? I couldn't confirm, either via this list or looking at commits whether Dreamplug support ever made it back into mainline uboot...
dreamplug patches have not been accepted into mainline because the proper way to do it (which globalscale didn't do in the binary they provided) is with a new machine id. This is already reserved [1]. U-boot shouldn't use the new mach-id until it is in mainline Linux. Linux won't accept new ARM boards unless they are moving towards device tree.
Is this something new?
Past six months or so...
You just need machine-id in mach-types.h to get in dreamplug patches mainlined into u-boot.
Yes, but mach-types.h is copied from Linux. Until it makes it into Linux, it won't trickle down to U-Boot.
I have added earlier machine id through http://www.arm.linux.org.uk/developer/machines/?action=new
Correct, this is how I added MACH_DREAMPLUG (3550).
Doesn't this work now?
it should, however, Linus' tree only has up to #3494 [1]. RMK's database shows it, though [2]. Maybe I just need to be more patient. ;-)
thx,
Jason.
