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.

powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P1010 i2c controllers

The i2c controllers on the P1010 have an erratum where the documented scheme for i2c bus recovery will not work (A-004447). A different mechanism is needed which is documented in the P1010 Chip Errata Rev L. Signed-off-by: Chris Packham Acked-by: Michael Ellerman Signed-off-by: Wolfram Sang

Pull powerpc updates from Michael Ellerman: - A series from Nick adding ARCH_WANT_IRQS_OFF_ACTIVATE_MM & selecting it for powerpc, as well as a related fix for sparc. - Remove support for PowerPC 601. - Some fixes for watchpoints & addition of a new ptrace flag for detecting ISA v3.1 (Power10) watchpoint features. - A fix for kernels using 4K pages and the hash MMU on bare metal Power9 systems with > 16TB of RAM, or RAM on the 2nd node. - A basic idle driver for shallow stop states on Power10. - Tweaks to our sched domains code to better inform the scheduler about the hardware topology on Power9/10, where two SMT4 cores can be presented by firmware as an SMT8 core. - A series doing further reworks & cleanups of our EEH code. - Addition of a filter for RTAS (firmware) calls done via sys_rtas(), to prevent root from overwriting kernel memory. - Other smaller features, fixes & cleanups.
