* [POWERPC] Fix bootwrapper builds with older gcc versionsJosh Boyer2008-02-19
| | | | | | | | | GCC versions before 3.4 did not support the -mcpu=440 option. Use -mcpu=405 for the 4xx specific bootwrapper files, as that has been around for much longer. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Fix dt_mem_next_cell() to read the full addressBecky Bruce2008-02-19
| | | | | | | | | | | | dt_mem_next_cell() currently does of_read_ulong(). This does not allow for the case where #size-cells and/or #address-cells = 2 on a 32-bit system, as it will end up reading 32 bits instead of the expected 64. Change it to use of_read_number instead and always return a u64.

This helps in identifying the exact hardware C-states behind the ACPI C-state definition. Idea is to export this through powertop, which will help to map the C-state reported by powertop to actual hardware C-state.

| * | sh: trapped io support V2Magnus Damm2008-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea is that we want to get rid of the in/out/readb/writeb callbacks from the machvec and replace that with simple inline read and write operations to memory. Fast and simple for most hardware devices (think pci). Some devices require special treatment though - like 16-bit only CF devices - so we need to have some method to hook in callbacks. This patch makes it possible to add a per-device trap generating filter. This way we can get maximum performance of sane hardware - which doesn't need this filter - and crappy hardware works but gets punished by a performance hit. V2 changes things around a bit and replaces io access callbacks with a simple minimum_bus_width value. In the future we can add stride as well.
