* arm: reimplement startup code in CSascha Hauer2010-05-033-253/+109
| | | | | | | Lets translate the startup code to a language we all understand better. Tested on pcm038 (arm v5) and pcm043 (arm v6). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* arm: move __mmu_cache_flush to bare_init sectionSascha Hauer2010-05-034-0/+9
| | | | | | | | Instead of having seperate cache flush functions in the startup code we want to call the generic functions. To accomplish this they have to be in the bare_init section. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Shutdown U-Boot before starting an OSSascha Hauer2009-03-191-0/+2
| | | | | | | | Some devices, especially the ones doing DMA should be disabled before giving control to an OS. We take the simple approach here: Just shutdown the devices in the reverse order they were activated. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | Memory layout can now be specified via kconfig options. Two possibilities exist: default layout means the layout is stack / malloc heap / U-Boot. The user can also specify fixed addresses for each TEXT_BASE / stack / malloc heap.
