2023-06-13arm64: dts: qcom: ipq5332: add few more reserved memory regionKathiravan T
In IPQ SoCs, bootloader will collect the system RAM contents upon crash for the post morterm analysis. If we don't reserve the memory region used by bootloader, obviously linux will consume it and upon next boot on crash, bootloader will be loaded in the same region, which will lead to loose some of the data, sometimes we may miss out critical information. So lets reserve the region used by the bootloader. Similarly SBL copies some data into the reserved region and it will be used in the crash scenario. So reserve 1MB for SBL as well. While at it, drop the size padding in the smem memory region.

2023-06-13arm64: dts: qcom: sa8540p-ride: Specify ethernet phy OUIAndrew Halaney
With wider usage on more boards, there have been reports of the following: [ 315.016174] qcom-ethqos 20000.ethernet eth0: no phy at addr -1 [ 315.016179] qcom-ethqos 20000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) which has been fairly random and isolated to specific boards. Early reports were written off as a hardware issue, but it has been prevalent enough on boards that theory seems unlikely. In bring up of a newer piece of hardware, similar was seen, but this time _consistently_. Moving the reset to the mdio bus level (which isn't exactly a lie, it is the only device on the bus so one could model it as such) fixed things on that platform. Analysis on sa8540p-ride shows that the phy's reset is not being handled during the OUI scan if the reset lives in the phy node: # gpio 752 is the reset, and is active low, first mdio reads are the OUI modprobe-420 [006] ..... 154.738544: mdio_access: stmmac-0 read phy:0x08 reg:0x02 val:0x0141 modprobe-420 [007] ..... 154.738665: mdio_access: stmmac-0 read phy:0x08 reg:0x03 val:0x0dd4 modprobe-420 [004] ..... 154.741357: gpio_value: 752 set 1 modprobe-420 [004] ..... 154.741358: gpio_direction: 752 out (0) modprobe-420 [004] ..... 154.741360: gpio_value: 752 set 0 modprobe-420 [006] ..... 154.762751: gpio_value: 752 set 1 modprobe-420 [007] ..... 154.846857: gpio_value: 752 set 1 modprobe-420 [004] ..... 154.937824: mdio_access: stmmac-0 write phy:0x08 reg:0x0d val:0x0003 modprobe-420 [004] ..... 154.937932: mdio_access: stmmac-0 write phy:0x08 reg:0x0e val:0x0014 Moving it to the bus level, or specifying the OUI in the phy's compatible ensures the reset is handled before any mdio access Here is tracing with the OUI approach (which skips scanning the OUI): modprobe-549 [007] ..... 63.860295: gpio_value: 752 set 1 modprobe-549 [007] ..... 63.860297: gpio_direction: 752 out (0) modprobe-549 [007] ..... 63.860299: gpio_value: 752 set 0 modprobe-549 [004] ..... 63.882599: gpio_value: 752 set 1 modprobe-549 [005] ..... 63.962132: gpio_value: 752 set 1 modprobe-549 [006] ..... 64.049379: mdio_access: stmmac-0 write phy:0x08 reg:0x0d val:0x0003 modprobe-549 [006] ..... 64.049490: mdio_access: stmmac-0 write phy:0x08 reg:0x0e val:0x0014 The OUI approach is taken given the description matches the situation perfectly (taken from ethernet-phy.yaml): - pattern: "^ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$" description: If the PHY reports an incorrect ID (or none at all) then the compatible list may contain an entry with the correct PHY ID in the above form. The first group of digits is the 16 bit Phy Identifier 1 register, this is the chip vendor OUI bits 3:18. The second group of digits is the Phy Identifier 2 register, this is the chip vendor OUI bits 19:24, followed by 10 bits of a vendor specific ID. With this in place the sa8540p-ride's phy is probing consistently, so it seems the floating reset during mdio access was the issue. In either case, it shouldn't be floating so this improves the situation. The below link discusses some of the relationship of mdio, its phys, and points to this OUI compatible as a way to opt out of the OUI scan pre-reset handling which influenced this decision.
