powerpc: Fix SPE Power ISA properties for e500v1 platforms

2022-09-28T09:22:13Z

Commit 2eb28006431c ("powerpc/e500v2: Add Power ISA properties to comply with ePAPR 1.1") introduced new include file e500v2_power_isa.dtsi and should have used it for all e500v2 platforms. But apparently it was used also for e500v1 platforms mpc8540, mpc8541, mpc8555 and mpc8560. e500v1 cores compared to e500v2 do not support double precision floating point SPE instructions. Hence power-isa-sp.fd should not be set on e500v1 platforms, which is in e500v2_power_isa.dtsi include file. Fix this issue by introducing a new e500v1_power_isa.dtsi include file and use it in all e500v1 device tree files.

powerpc/85xx: P2020: Add law_trgt_if property to PCIe DT nodes

2022-07-28T06:22:14Z

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: dts: t1040rdb: fix ports names for Seville Ethernet switch

2022-02-02T09:32:10Z

On board rev A, the network interface labels for the switch ports written on the front panel are different than on rev B and later. This patch fixes network interface names for the switch ports according to labels that are written on the front panel of the board rev B. They start from ETH3 and end at ETH10. This patch also introduces a separate device tree for rev A. The main device tree is supposed to cover rev B and later.

powerpc: dts: t104xrdb: fix phy type for FMAN 4/5

2022-01-31T02:45:24Z

T1040RDB has two RTL8211E-VB phys which requires setting of internal delays for correct work. Changing the phy-connection-type property to `rgmii-id` will fix this issue.

powerpc: retire sbc8641d board support

2021-08-26T14:48:18Z

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.
