* [POWERPC] QE: Add support for Freescale QUICCEngine UARTTimur Tabi2008-01-23
| | | | | | | | | | Add support for UART serial ports using a Freescale QUICCEngine. Update booting-without-of.txt to define new properties for a QE UART node. Update the MPC8323E-MDS device tree to add UCC5 as a UART. Update the QE library to support slow UCC devices and modules.

* [POWERPC] QE: Add ability to upload QE firmwareTimur Tabi2008-01-23
| | | | | | | | | | | Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Added description of a new QE firmware node to booting-without-of.txt. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* phy/fixed.c: rework to not duplicate PHY layer functionalityVitaly Bordug2008-01-23
| | | | | | | | | | | | | | | | With that patch fixed.c now fully emulates MDIO bus, thus no need to duplicate PHY layer functionality. That, in turn, drastically simplifies the code, and drops down line count. As an additional bonus, now there is no need to register MDIO bus for each PHY, all emulated PHYs placed on the platform fixed MDIO bus. There is also no more need to pre-allocate PHYs via .config option, this is all now handled dynamically.

* [POWERPC] FSL: Rework PCI/PCIe support for 85xx/86xxKumar Gala2008-01-23
| | | | | | | | | | | The current PCI code for Freescale 85xx/86xx was treating the virtual P2P PCIe bridge as a transparent bridge. Rather than doing that fixup the virtual P2P bridge by copying the resources from the PHB. Also, fixup a bit of the code for dealing with resource_size_t being 64-bits and how we set ATMU registers for >4G. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Fixup transparent P2P resourcesKumar Gala2008-01-23
| | | | | | | | For transparent P2P bridges the first 3 resources may get set from based on BAR registers and need to get fixed up. Where as the remainder come from the parent bus and have already been fixed up. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] Ensure we only handle PowerMac PCI bus fixup for memory resourcesKumar Gala2008-01-23
| | | | | | | | | | The fixup code that handles the case for PowerMac's that leave bridge windows open over an inaccessible region should only be applied to memory resources (IORESOURCE_MEM). If not we can get it trying to fixup IORESOURCE_IO on some systems since the other conditions that are used to detect the case can easily match for IORESOURCE_IO.

* [POWERPC] Fix handling of memreserve if the range lands in highmemKumar Gala2008-01-23
| | | | | | | | | | | | | | | | | | | There were several issues if a memreserve range existed and happened to be in highmem: * The bootmem allocator is only aware of lowmem so calling reserve_bootmem with a highmem address would cause a BUG_ON * All highmem pages were provided to the buddy allocator Added a lmb_is_reserved() api that we now use to determine if a highem page should continue to be PageReserved or provided to the buddy allocator. Also, we incorrectly reported the amount of pages reserved since all highmem pages are initally marked reserved and we clear the PageReserved flag as we "free" up the highmem pages.

The choices available are 64K and 16M when the base page size is 4k. It defaults to 16M (previously the only only choice) if nothing or an invalid choice is specified.
