2007-02-07[POWERPC] Fix kernel build errors for mpc8272ads and mpc8560adsVitaly Bordug
Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

2007-02-07[POWERPC] cpm2: CPM2 interrupt controller fixVitaly Bordug
This contains important fixes for the CPM2 PIC code. Eliminated CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt mapping. Updated devicetree files to reflect that. Changed direct IC-related IO accesses to the IO accessors. Fixed all the sense values to keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs and hence could be hardly usable.

2006-12-20[POWERPC] Fix build of cell zImage.initrdBenjamin Herrenschmidt
The patch adding support for zImage.ps3 didn't add a zImage.initrd.ps3 target causing builds of zImage.initrd to fail when ps3 is included in the .config. The current method of generating ps3 images doesn't support initrd's yet, so we create a dummy target that only displays a warning message instead.

2006-12-04[POWERPC] ps3: add a default zImage targetArnd Bergmann
It's currently not possible to build the default zImage target if PS3 is the only selected platform. This is a hack to fall back to building the pseries style zImage, so the build is successful. This will probably change in the future, if someone writes a PS3 specific boot wrapper. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

2006-12-04[POWERPC] Cleanup zImage handling of kernel entry with flat device treeDavid Gibson
This makes 2 changes to clean up the flat device tree handling logic in the zImage wrapper. First, there were two callbacks from the dt_ops structure used for producing a final flat tree to pass to the kerne: dt_ops.ft_pack() which packed the flat tree (possibly a no-op) and dt_ops.ft_addr() which retreived the address of the final blob. Since they were only ever called together, this patch combines the two into a single new callback, dt_ops.finalize(). This new callback does whatever platform-dependent things are necessary to produce a final flat device tree blob, and returns the blob's addres. Second, the current logic calls the kernel with a flat device tree if one is build into the zImage wrapper, otherwise it boots the kernel with a PROM pointer, expecting the kernel to copy the OF device tree itself. This approach precludes the possibility of the platform wrapper code building a flat device tree from whatever platform-specific information firmware provides. Thus, this patch takes the more sensible approach of invoking the kernel with a flat tree if the dt_ops.finalize callback provides one (by whatever means). So, the dt_ops.finalize callback can be NULL, or can be a function which returns NULL. In either case, the zImage wrapper logic assumes that this is a platform with OF and invokes the kernel accordingly.

2006-12-04[POWERPC] Small clarification of initrd handlingDavid Gibson
This patch makes the handling of the initrd (or initramfs) in the zImage wrapper a little easier to follow. Instead of passing the initrd addresses out from prep_kernel() via the cryptic a1 and a2 parameters, use the global struct add_range, 'initrd'. prep_kernel() already passes information through the 'vmlinux' addr_range struct, so this seems like a reasonable extension. Some comments also clarify the logic with prep_kernel(): we use an initrd included in the zImage if present, otherwise we use an initrd passed in by the bootloader in the a1 and a2 parameters (yaboot, at least, uses this mechanism to pass an initrd).

The value returned by ft_find_device() is a phandle which is really an index into the phandle table. The phandle table contains the address of the corresponding node. When the flat dt is edited/moved, the node pointers in the phandle table are updated accordingly so no phandles kept by the caller become stale. Signed-off-by: Mark A.

2006-09-28[POWERPC] Create a "wrapper" script and use it in arch/powerpc/bootPaul Mackerras
This puts the knowledge of how to create various sorts of zImage wrappers into a script called "wrapper" that could be used outside of the kernel tree. This changes arch/powerpc/boot so it first builds the files that the wrapper script needs, then runs it to create whatever flavours of zImage are required. This version does uImages as well. The zImage names are changed slightly; zImage.pseries is the one with the PT_NOTE program header entry added, and zImage.pmac is the one without. If the zImage.pseries gets made, it will also get hardlinked to zImage; otherwise, if zImage.pmac is made, it gets hardlinked to zImage. Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-09-21POWERPC: Bring the fs_no calculation to the relevant SoC enumerationVitaly Bordug
The fs_no mean used to be fs_enet driver driven, hence it was an enumeration across all the possible fs_enet "users" in the SoC. Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.

The brand new devicetree nodes are introduced (intending to be a subset of the QuiccEngine-equipped models, with dts sources placed into the kernel according to the new convention. Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART update), the both TSEC eth ,FCC Eths, and both SCC UARTs are working. The relevant drivers are still capable to drive users in ppc, which was verified with 8272ADS (SCC uart+FCC eth).
