* [POWERPC] cpm_uart: Issue STOP_TX command before initializing console.Scott Wood2007-10-03

* [POWERPC] cpm_uart: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING ↵Scott Wood2007-10-03
| | | | | | | | | | | | | | | | is set. The existing OF glue code was crufty and broken. Rather than fix it, it has been removed, and the serial driver now talks to the device tree directly. The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).

* [POWERPC] bootwrapper: Add fsl_get_immr() and 8xx/pq2 clock functions.Scott Wood2007-10-03
| | | | | | | | | | | | | | | | | | | | fsl_get_immr() uses /soc/ranges to determine the immr. mpc885_get_clock() transforms a crystal frequency into a system frequency according to the PLL register settings. pq2_get_clocks() does the same as the above for the PowerQUICC II, except that it produces several different clocks. The mpc8xx/pq2 set_clocks() functions modify common properties in the device tree based on the given clock data. The mpc885/pq2 fixup_clocks() functions call get_clocks(), and pass the results to set_clocks().

* [POWERPC] bootwrapper: Support all-in-one PCI nodes in cuboot-pq2.Scott Wood2007-10-03
| | | | | | | | | | | | Consensus was reached to put PCI nodes at the root of the tree (and not under /soc), but the phandle to a control node was rejected in favor of simply not worrying about /pci/reg overlapping /soc/ranges. This updates cuboot-82xx to not look for the phandle.

* [POWERPC] Introduce new CPM device bindings.Scott Wood2007-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

* [POWERPC] CPM: Change from fsl,brg-frequency to brg/clock-frequencyScott Wood2007-10-03
| | | | | | | | | | | | | As suggested by David Gibson, now that we have a separate node for the baud rate generators, it's better to use the standard clock-frequency property than a cpm-node-level fsl,brg-frequency property. This patch updates existing places where fsl,brg-frequency is used. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [PPC] Use cpu setup routines from cpu_setup_44x.S for ARCH=ppcPaul Mackerras2007-10-03
| | | | | | | | | | | | | | Commit 8112753bb2c0045398c89d0647792b39805f6d40 made 44x in ARCH=powerpc builds use cpu setup routines in cpu_setup_44x.S, but didn't make a similar change for ARCH=ppc, and consequently the ARCH=ppc builds fail with undefined symbols (since both use the same cputable.c). This fixes it by including cpu_setup_44x.S in the ARCH=ppc builds, and by taking out the now-redundant FPU initialization in arch/ppc/kernel/head_44x.S.

| * [POWERPC] Fix cpm_uart driverJochen Friedrich2007-09-25
| | | | | | | | | | | | | | | | | | | | in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp. On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't be used for arithmetric compare operations with virtual addresses returned by cpm_dpram_addr. This patch changes the assignment to use cpm_dpram_addr as well, like in cpm_uart_cpm2.h. Signed-off-by: Jochen Friedrich <jochen@scram.de>

| * [PPC] Fix cpm_dpram_addr returning phys mem instead of virt memJochen Friedrich2007-09-25
| | | | | | | | | | | | | | | | | | | | | | | | cpm_dpram_addr returns physical memory of the DP RAM instead of iomapped virtual memory. As there usually is a 1:1 MMU map of the IMMR area, this is often not noticed. However, cpm_dpram_phys assumes this iomapped virtual memory and returns garbage on the 1:1 mapped memory causing CPM1 uart console to fail. This patch fixes the problem (copied from the powerpc tree). Signed-off-by: Jochen Friedrich <jochen@scram.de>
