ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs size

2010-09-23T06:49:49+00:00

This patch changes the behaviour of the fdt_fixup_nor_flash_node()
function. Now it doesn't patch the size of the "reg" property with the
chip-select size, but with the size returned from the new function
flash_get_bank_size(). This function will return per weak default the
flash size of the bank (bank = chip-select numer) detected by the flash
driver. If this does not fit your needs, this function may be overridden
by a board specific one.

For this the parameters needed to be changed. So I intentionally squashed
the PPC4xx stuff using this routine into this patch. Otherwise it would
not be git-bisectable anymore.

The board specific function for the AMCC/APM Ebony eval board is now
included in this patch version.

fdt: Add function to alloc phandle values

2010-07-26T18:07:56+00:00

If we are creating reference (handles) to nodes in a device tree we need
to first create a new phandle in node and this needs a new phandle
value.  So we search through the whole dtb to find the max phandle value
and return the next greater value for a new phandle allocation.

fdt: Add fdt_node_offset_by_compat_reg helper

2010-07-20T09:40:06+00:00

Given a compatible string and physical address try and find a node that
matches.  This is useful when we want to find a specific device node to
update (for example if we have multiple PCI nodes we can use the
physical address to distinguish them when trying to update the device
tree).

fdt: Add fdt_translate_address to convert reg node to cpu phys addr

2010-07-20T09:40:00+00:00

This code is extracted out of the Linux Kernel code from
arch/powerpc/kernel/prom_parse.c.

We maintain some of the same structure to support multiple bus types even
though we only have one in the current code.  In the future we might want
to translate across a PCI bus and thus it will be easier to add that
functionality back in.

powerpc/8xxx: Distinguish between incompatible SEC h/w types

2010-07-16T15:55:07+00:00

CONFIG_SYS_FSL_SEC_COMPAT is set to 2 for the SEC 2.x and SEC 3.x.
Parts with newer SEC h/w versions will increment the number to
accomodate incompatible code changes.

fdt: Add fdt_del_node_and_alias helper

2010-04-07T05:08:18+00:00

Add a helper function that given an alias will delete both the node
the alias points to and the alias itself

fdt_support: add partitions fixup in mtd node

2010-03-21T21:44:59+00:00

Allow overwriting defined partitions in the device tree blob
using partition info defined in the 'mtdparts' environment
variable.

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.

83xx: Replace CONFIG_MPC83XX with CONFIG_MPC83xx

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

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.
