Subject: rework MMU support
Date: Mon, 1 Aug 2011 15:26:43 +0200 [thread overview]
Message-ID: <20110801132643.GH6255@game.jcrosoft.org> (raw)
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
