If I apply this on top of your v4 patch on top of 2011.06, I only need two tweaks to build: MACH_TYPE_DREAMPLUG which will obviously sort itself out, and s/MPP7_GP0/MPP7_GPO/ in board/Marvell/dreamplug/dreamplug.c .
Yes, what an embarrassing typo, that shouldn't even build. :-( Well, it was RFC...
It has not yet been tested on a plug. Do you have a working OpenOCD config for flash/ram?
Sort of. The openocd config for the sheevaplug/guruplug is what I use, and is distributed on the dreamplug download page [1]. It does _not_ have support for the SPI flash. You can also use the sheevaplug.cfg shipped with openocd. So, I use openocd or tftp to transfer to RAM, then use u-boot to write to flash.
To test images, or to reflash, I load the known-good u-boot into RAM via openocd, then I'll either reflash it or load a new testing one from there.
To write a u-boot.kwb test image to flash, here is what I do:
openocd$ sheevaplug_init openocd$ load_image u-boot # known good from Marvell openocd$ load_image u-boot.kwb 0x00800000 # monster I created openocd$ resume 0x00600000 # run the known good
then, in u-boot
u-boot$ sf probe 0 u-boot$ sf erase 0x0 0x100000 u-boot$ sf write 0x00800000 0x0 0x100000
If time allows, I'd like to add SPI flash support to OpenOCD. Unfortunately, time is short and the above process works.
