fdt_support: Add multi-serial support for stdout fixup

2009-10-27T02:35:50+00:00

Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.

fdt: Fix fdt padding issue for initrd mem_rsv

2009-10-24T20:39:51+00:00

Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.

Fix this be adding a second mem_rsv into the size calculation.  We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.

fdt: Add fdt_fixup_nor_flash_size() to fixup NOR FLASH size in dtb

2009-10-23T13:55:23+00:00

This function can be used to update the size in the "reg" property
of the NOR FLASH device nodes. This is necessary for boards with
non-fixed NOR FLASH sizes.

fdt: Fix fdt_pci_dma_ranges handling of 64-bit ranges

2009-08-09T21:13:56+00:00

If the size of a region equal to 4G it can't be represnted in a 32-bit
BAR so we should have marked that case as MEM64.

Additionally bump the number of inbound windows up to 4 to handle the
fact that Freescale PPCs that have an implicit window for CCSRBAR.

83xx: Replace CONFIG_MPC83XX with CONFIG_MPC83xx

2009-06-12T18:47:17+00:00

Use the standard lowercase "xx" capitalization that other Freescale
architectures use for CPU defines to prevent confusion and errors

pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarity

2009-02-07T22:50:04+00:00

The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.

Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

fdt_resize(): fix actualsize calculations with unaligned blobs

2009-01-17T18:03:29+00:00

The code in fdt_resize() to extend the fdt size to end on a page boundary
is wrong for fdt's not located at an address aligned on a page boundary.
What's even worse, the code would make actualsize shrink rather than grow
if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(),
causing fdt_add_mem_rsv to fail.

Fix it by aligning end address (blob + size) to a page boundary instead.
For aligned fdt's this is equivalent to what we had before.

fdt_resize(): ensure minimum padding

2008-10-31T00:37:57+00:00

fdt_add_mem_rsv() requires space for a struct fdt_reserve_entry
(16 bytes), so make sure that fdt_resize at least adds that much
padding, no matter what the location or size of the fdt is.

fdt: Added helper to set PCI dma-ranges property

2008-10-24T22:34:57+00:00

Added fdt_pci_dma_ranges() that parses the pci_region info from the
struct pci_controller and populates the dma-ranges based on it.

The max # of windws/dma-ranges we support is 3 since on embedded
PowerPC based systems this is the max number of windows.

Add helper functions to return find a node and return it's property
or a default value.
