| * kbuild: use $(src) instead of $(srctree)/$(src) for source directoryMasahiro Yamada2024-05-101-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for checked-in source files. It is merely a convention without any functional difference. In fact, $(obj) and $(src) are exactly the same, as defined in scripts/Makefile.build: src := $(obj) When the kernel is built in a separate output directory, $(src) does not accurately reflect the source directory location. While Kbuild resolves this discrepancy by specifying VPATH=$(srctree) to search for source files, it does not cover all cases. For example, when adding a header search path for local headers, -I$(srctree)/$(src) is typically passed to the compiler. This introduces inconsistency between upstream and downstream Makefiles because $(src) is used instead of $(srctree)/$(src) for the latter. To address this inconsistency, this commit changes the semantics of $(src) so that it always points to the directory in the source tree. Going forward, the variables used in Makefiles will have the following meanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source tree Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced with $(src).

* powerpc: drop MPC85xx_CDS platform supportPaul Gortmaker2023-06-215-1216/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8541/8548/8555 Configurable Development System (CDS) were the vehicle used to provide evaluation of the 1st e500-v2 CPUs around 2007. Similar to the earlier MPC83xx-MDS systems we removed, the "brains" exist on a PCI-X card, but additional connectors exist to the right of the PCI-X slot, two structural metal pins are used to provide stability in a vertical ATX mounting, and the CPU is now on a daughter-card vs. a clamped down BGA. Given the extra complexity and risk of connector damage, the 8548CDS I had access to came pre-assembled in a basic white Antec case common for that era, and I'm inclined to assume that was the default. Power was typical "Pentium4" 2005 ATX - the main 20 pin connector went to the PCI ATX form factor backplane, and the 4 pin black/yellow went to the CPU card. Like previous evaluation boards, they attempted to provide break-out connectors for as many features as possible, and that made for a fairly complex looking system. In any case, these are over 15 years old, and fairly complex systems, originally made for a small group of industry related people, and made for use where quiet fan operation wasn't important. Given that, it makes sense to remove support from them in 2023.

| | | | | | | | | | | | | | | | | | | | | | | Based on the revision history in the manual(s), these e500-v1 platforms were first available around 2002. Like a lot of evaluation boards, they attempted to provide break-out connectors for all possible features, and that combined with four PCI-X slots (and the age/era) meant for a considerably large board. As I recall it, from a Linux point of view, the biggest difference between 8540 and 8560 was in the UART implementation, and that is reflected in a diff of the defconfigs. In any case, these are over 20 years old, and by today's standards only have a small amount of DDR1 memory, and were not widely available. Given that, it makes sense to remove support from them in 2023.

| | | | | | | | | | | | | | | | | | | | | | | | | There is no denying that this was an interesting platform in its day. Access to a SMP powerpc platform became a bit more obtainable for folks in the BSP industry in the 2007 era, thanks to this platform. Add to that the move to the black Antec case vs. the generic white 2005 era case of the MPC8548CDS or the retro 1950s 1/2 height horizontal case of the HPC II, and it was pretty interesting to people like myself then. However, like all the other evaluation platforms, the overall system was complex out of necessity, as it tried to showcase all possible features and use-cases. That included an AMP option, where you could run two bootloaders and two kernels over two serial consoles. Peripheral sharing got a bit more tricky when you got to the hard disk and similar. In any case we still have the same circumstance. A relatively rare and expensive evaluation platform that is now 15+ years old and not out there in large numbers in the general public. Removal in 2023 just makes sense.

Since the first QSGMII PCSs share an address with the SGMII and XFI PCSs, we only add new nodes for PCSs 2-4. This avoids address conflicts on the bus.

| | | | | | | | | | | | | | | | | | | | | | | DT law_trgt_if property defines Local Access Window Target Interface. Local Access Window Target Interface is used for identifying individual peripheral and mapping its memory to CPU. Interface id is defined by hardware itself. U-Boot uses law_trgt_if DT property in PCIe nodes for configuring memory mapping of individual PCIe controllers. Linux kernel fsl_pci.c driver currently does not touch Local Access Window and expects that U-Boot configures it properly. Add law_trgt_if property to PCIe DT nodes for P2020. This allows usage of kernel P2020 PCIe DT nodes in U-Boot. And therefore allows to share P2020 DTS files between Linux kernel and U-Boot.

* powerpc: retire sbc8641d board supportPaul Gortmaker2021-08-271-176/+0
| | | | | | | | | | | | | | | | | | | | | | The support was for this was added to mainline over 12 years ago, in v2.6.26 [4e8aae89a35d] just around the ppc --> powerpc migration. I believe the board was introduced shortly after the sbc8548 board, making it roughly a 14 year old platform - with the CPU speed and memory size typical for that era. I haven't had one of these boards for several years, and availability was discontinued several years before that. Given that, there is no point in adding a burden to testing coverage that builds all possible defconfigs, so it makes sense to remove it. Of course it will remain in the git history forever, for anyone who happens to find a functional board and wants to tinker with it.
