If this happens before Low memory is mapped (which is done now by map_lowmem()) the system will hang, because the Memblock core will try to operate with virtual addresses which aren't mapped yet. In ARM code, the memblock resizing is allowed (memblock_allow_resize()) from arm_memblock_init() which is called before map_lowmem(), so this may lead to an error as described above. Hence, allow Memblock resizing later during init, from bootmem_init() when all appropriate mappings are ready.

Also some compatibility definitions are added to make the transition from legacy API to DMA engine easier. The biggest hack here is passing const char * pointers through DMA resource, casted to unsigned long, but this is how Samsung DMA wrappers (used to support both s3c-dma and DMA engine in drivers) are designed.

Note that we still need to initialize various platform data quirks to keep things working until n8x0 drivers support device tree. Here's a rough todo list for the people using n8x0: 1. Update menelaus for device tree and set up regulators at least for the MMC driver 2. Remove the MMC regulator platform data callback by using the Menlaus regulators directly in the driver passed from the .dts file 3. Update GPMC connected devices for onenand and tusb6010 for device tree We're planning to remove all legacy platform data for mach-omap2 over next few merge cycles, so if people are still using n8x0, please fix the issues above.

For twl4030-keypad we're still missing the binding, but support for that should be trivial to add once the driver has been updated. MUSB I'm pretty sure I got got to enumerate once, but I suspect the battery charging somehow disrupts it and it's not enumerating in general for some reason.

I have one, but I'm not using it because of it's large size, and I doubt anybody else is using it either. We do have minimal omap2420-h4.dts in place, so if anybody wants more support on H4, patches are welcome. So let's just remove it as that helps us making mach-omap2 to be device tree only.
