[POWERPC] Don't complain if size-cells == 0 in prom_parse()

2007-05-12T01:32:48+00:00

An mdio bus scan was added with ucc_geth phylib
migration patches, now machines complain on boot, saying:

prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@00
prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@01

since size-cells can indeed be 0, this patch fixes the check.

[POWERPC] Uninline of_iomap function

2007-05-02T10:04:29+00:00

There is no big reason to have that function inlined.

[POWERPC] Move of_irq_to_resource from prom.h to prom_parse.c

2007-05-02T06:40:55+00:00

In the powerpc architecture, of_irq_to_resource, currently sitting in
prom.h, needs irq_of_parse_and_map and NO_IRQ from asm-powerpc/irq.h.
The solution suggested by Benjamin Herrenschmidt is to move it to
arch/powerpc/kernel/prom_parse.c.

[POWERPC] Rename prom_n_size_cells to of_n_size_cells

2007-04-12T17:55:18+00:00

This is more consistent and gets us closer to the Sparc code.

[POWERPC] Fix warning in prom_parse.c of_irq_map_oldworld()

2007-03-07T17:09:33+00:00

This function spews a warning due to possible use of an uninitialized
variable. This can happen on broken device-trees or when called with
a NULL argument. Makes ure we properly fail instead.

[POWERPC] add of_get_mac_address and update fsl_soc.c to use it

2007-02-16T23:21:25+00:00

Add function of_get_mac_address(), which obtains the best MAC address to use
from the device tree by checking various properties in order.  The order is:
'mac-address', then 'local-mac-address', then 'address'.  It skips properties
that contain invalid MAC addresses, which were probably not initialized
by U-Boot.

Update gfar_of_init() and fs_enet_of_init() in fsl_soc.c to call
of_get_mac_address().

[POWERPC] Workaround oldworld OF bug with IRQs & P2P bridges

2006-12-20T05:37:47+00:00

On some oldworld PowerMacs, OF doesn't assign interrupts properly
beyond P2P bridges. Fortunately, the fix is easy as all those machines
just wire all IRQ lines together to one IRQ which is assigned to the
bridge itself. We already have a special function for parsing Apple
OldWorld interrupts which are special, so let's add to it the ability
to walk up the PCI tree to find interrupts.

This fixes irqs on the lower slots of s900 clones among others.

[POWERPC] Fix OF pci flags parsing

2006-12-04T09:41:49+00:00

For PCI devices with only io ports, of_bus_pci_get_flags() will fall
through and still mark the resource as IORESOURCE_MEM.
