-Subject: [PATCH 2/2] usb: dwc2: add support for other Lantiq SoCs
-
-The size of the internal RAM of the DesignWare USB controller changed
-between the different Lantiq SoCs. We have the following sizes:
-
-Amazon + Danube: 8 KByte
-Amazon SE + arx100: 2 KByte
-xrx200 + xrx300: 2.5 KByte
-
-For Danube SoC we do not provide the params and let the driver decide
-to use sane defaults, for the Amazon SE and arx100 we use small fifos
-and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
-The auto detection of max_transfer_size and max_packet_count should
-work, so remove it.

-Some write buffer functions are not used when FORCE_WORD_WRITE is set to 1.
-So the compile warning messages are output if FORCE_WORD_WRITE is 1. To
-resolve this disable the write buffer functions if FORCE_WORD_WRITE is 1.
-
-This is similar fix to: 557c759036fc3976a5358cef23e65a263853b93f.

-Subject: [PATCH] MIPS: lantiq: enable all hardware interrupts on second VPE
-
-This patch is needed to handle interrupts by the second VPE on the Lantiq
-ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
-the second VPE results in a hang. Currently, the vsmp_init_secondary()
-function is responsible for enabling these interrupts. It only enables
-Malta-specific interrupts (SW0, SW1, HW4 and HW5).
-
-The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
-interrupts are wired to an ICU instance. Each VPE has an independent
-instance of the ICU. The mapping of the ICU interrupts is shown below:
-SW0(IP0) - IPI call,
-SW1(IP1) - IPI resched,
-HW0(IP2) - ICU 0-31,
-HW1(IP3) - ICU 32-63,
-HW2(IP4) - ICU 64-95,
-HW3(IP5) - ICU 96-127,
-HW4(IP6) - ICU 128-159,
-HW5(IP7) - timer.
-
-This patch enables all interrupt lines on the second VPE.
-
-This problem affects multithreaded SoCs with a custom interrupt controller.
-SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
-that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
-future, this may be replaced with some generic solution.
-
-Tested on Lantiq xRX200.

-Subject: [PATCH] MIPS: lantiq: register smp_ops on non-smp platforms
-
-Lantiq uses a common kernel config for devices with 24Kc and 34Kc cores.
-The changes made previously to add support for interrupts on all cores
-work on 24Kc platforms with SMP disabled and 34Kc platforms with SMP
-enabled. This patch fixes boot issues on Danube (single core 24Kc) with
-SMP enabled.

-Fixes: 730320fd770d ("MIPS: lantiq: enable all hardware interrupts on second VPE")

-Subject: [PATCH] mtd: rawnand: xway: don't yield while holding spinlock
-
-The nand driver normally while waiting for the device to become ready;
-this is normally fine, but xway_nand holds the ebu_lock spinlock, and
-this can cause lockups if other threads which use ebu_lock are
-interleaved. Fix this by waiting instead of polling.
-
-This mainly showed up as crashes in ath9k_pci_owl_loader (see
-https://github.com/openwrt/openwrt/issues/9829 ), but turning on
-spinlock debugging shows this happening in other places too.
-
-This doesn't seem to measurably impact boot time.

-Subject: [PATCH] net: lantiq_xrx200: increase buffer reservation
-
-If the user sets a lower mtu on the CPU port than on the switch,
-then DMA inserts a few more bytes into the buffer than expected.
-In the worst case, it may exceed the size of the buffer. The
-experiments showed that the buffer should be a multiple of the
-burst length value. This patch rounds the length of the rx buffer
-upwards and fixes this bug. The reservation of FCS space in the
-buffer has been removed as PMAC strips the FCS.

-This patch adds support for scatter gather DMA. DMA in PMAC splits

-less than the MTU of the switch. The first buffer starts at an

-Subject: net: dsa: lantiq_gswip: enable jumbo frames on GSWIP
-
-This enables non-standard MTUs on a per-port basis, with the overall
-frame size set based on the CPU port.
-
-When the MTU is not changed, this should have no effect.
-
-Long packets crash the switch with MTUs of greater than 2526, so the
-maximum is limited for now. Medium packets are sometimes dropped (e.g.
-TCP over 2477, UDP over 2516-2519, ICMP over 2526), Hence an MTU value
-of 2400 seems safe.

-Subject: [PATCH 5/5] net: lantiq: configure the burst length in ethernet
- drivers
-
-Configure the burst length in Ethernet drivers. This improves
-Ethernet performance by 58%. According to the vendor BSP,
-8W burst length is supported by ar9 and newer SoCs.
-
-The NAT benchmark results on xRX200 (Down/Up):
-* 2W: 330 Mb/s
-* 4W: 432 Mb/s 372 Mb/s
-* 8W: 520 Mb/s 389 Mb/s
-
-Tested on xRX200 and xRX330.

-
-When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll
-function immediately returns an error.
-This is incorrect for two reasons:
-* the function terminates without enabling interrupts or scheduling NAPI,
-* the error code (-ENOMEM) is returned instead of the number of received
-packets.
-
-After the first memory allocation failure occurs, packet reception is
-locked due to disabled interrupts from DMA..

-Introduce a new GSWIP_TABLE_MAC_BRIDGE_PORT macro and use it throughout
