We have been getting away with this because the data_offset was
In hpte_init_native() we call tlb_batching_enabled() to decide if we

tlb_batching_enabled() checks the _unflattened_ device tree, to see
if we are running on a nighthawk.

Hi,
I'm working on a custom board based on P1020 with two (identical) PCI

The work is derived from another board with a single instance of that
device.
The system is based on u-boot-2009.11 and Linux 2.6.34.6
The pci command on u-boot, shows me both the PCI controllers and

I mean there are two controllers and both of them have a device subtended

u-boot can see both devices, linux detects only the device attached to the

Hello,
Is it possible to determine if _native_ isel is available from userspace
