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: 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.

powerpc: Fix bootm to boot up again with a Ramdisk

2008-09-13T00:03:38+00:00

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

fdt: refactor initrd related code

2008-08-26T21:45:20+00:00

Created a new fdt_initrd() to deal with setting the initrd properties
in the device tree and fixing up the mem reserve.  We can use this
both in the choosen node handling and lets us remove some duplicated
code when we fixup the initrd info in bootm on PPC.

common fdt support code.

bootm: Set working fdt address as part of the bootm flow

2008-08-26T21:37:54+00:00

Set the fdt working address so "fdt FOO" commands can be used as part
of the bootm flow.  Also set an the environment variable "fdtaddr"
with the value.
