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.

fdt: Add fdt_getprop_u32_default helpers

2008-10-24T22:34:52+00:00

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

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.

fdt: refactor fdt resize code

2008-08-26T21:43:36+00:00

Move the fdt resizing code out of ppc specific boot code and into
common fdt support code.

fdt: rework fdt_fixup_ethernet() to use env instead of bd_t

2008-08-21T00:07:43+00:00

Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet
interfaces.

fdt_support: fdt_fixup_dr_usb: add support for phy_type fixups

2008-07-16T19:16:44+00:00

Currently U-Boot can only fixup the usb dr_mode, but some boards (namely
MPC8315E-RDB) can use two PHY types: ULPI (stand-alone OTG port) or UTMI
(connected to the four-ports hub, usb host only).

This patch implements support for passing Dual-Role USB controller's
device tree property phy_type through the usb_phy_type environment
variable.
