Hi,
This series reworks the barebox MMU support. We now use second
level page tables which allows us to remap the dma coherent area
dynamically. We don't have to map our sdram twice anymore which
helps us on newer systems with big memory.
As a bonus there is no board specific MMU code anymore. All a board
has to do to enable MMU support via Kconfig is to register its SDRAM banks
at mem_initcall
The following changes since commit b821d73607cc6387b1ee588af97a44e8eb2b4fe2:
Merge branch 'resource' of git://uboot.jcrosoft.org/barebox into next (2011-08-01 14:10:38 +0200)
are available in the git repository at:
git://uboot.jcrosoft.org/barebox.git mmu
Jean-Christophe PLAGNIOL-VILLARD (2):
arm: introduce arm_add_mem_device to register dram device
init: introduce mem, mmu and postmmu initcall
Sascha Hauer (7):
ARM cache l2x0: depend on MMU
ARM: move armlinux_add_dram to location which is always compiled
ARM l2x0: make init function static inline if l2 is not available
ARM: pass size to dma_free_coherent
ARM boards: move sdram setup before mmu setup
ARM: rework MMU support
ARM boards: remove now unnecessary mmu calls

We want to use the memory banks later in the MMU which is
independent of Linux, so move this to a location which is
always compiled.
Also, make the memory bank list global and add an iterator
for it.

on ARM we need to init all the memory before the mmu and before any drivers
use dma_alloc_coherent

The new MMU setup will need SDRAM base addresses and sizes.
For this reason convert the MMU enabled ARM boards:
- move mem setup to mem_initcall. This is early but
still makes sure that we already have the console available
- move MMU setup in this initcall temporary as after the mmu_init will generic

To: barebox
From: Sascha Hauer <s.hauer@pengutronix.de>
In barebox we used 1MiB sections to map our SDRAM cachable. This
has the drawback that we have to map our sdram twice: cached for
normal sdram and uncached for DMA operations. As address space gets
sparse on newer systems we are sometines unable to find a suitably
big enough area for the dma coherent space.
This patch changes the MMU code to use second level page tables.
With it we can implement dma_alloc_coherent as normal malloc, we
just have to remap the allocated area uncached afterwards and map
it cached again after free().
This makes arm_create_section(), setup_dma_coherent() and mmu_enable()
noops.

merged up to 7/9. The MMU rework needs some changes to v1 which I
haven't posted yet. It does not work correctly on armv7 as these
processors need slightly different second level page table entries.
Also, I added the appropriate KEEP directives to
include/asm-generic/barebox.lds.h to make this branch work. Would be
good if you could give your patches at least *some* testing.
