Review comments at @config/sources/families/realtek-rtd129x.conf:
- Around line 82-86: Update the RTD1395 boot-device configuration so the
fallback root device points to partition 2, matching the root filesystem layout;
alternatively, make the UUID override mandatory so boot cannot fall back to
partition 1. Preserve the FAT loader on partition 1 in the layout generated
around fat_start and fat_size.

@patch/kernel/archive/realtek-rtd129x-6.18/0043-net-realtek-r8169soc-do-not-receive-into-a-slot-with.patch:
- Around line 30-36: In the empty-buffer branch of rtl_rx, schedule a reset task
before breaking so polling does not repeatedly stop at the same slot. Use
rtl_schedule_task with RTL_FLAG_TASK_RESET_PENDING, preserving the existing
error logging and break behavior.

@patch/kernel/archive/realtek-rtd129x-6.18/0056-PCI-rtd139x-add-the-RTD1395-PCIe-host-controller.patch:
- Around line 141-144: Reduce RTD_CFG_RD_TIMEOUT_US to a low-millisecond timeout
so atomic config reads do not busy-wait for up to a second; also update
rtd139x_cfg_read to stop retrying when the poll times out, even if DLLP error
bits are set. Apply the same timeout adjustment to the 7.3 patch copy.

- Around line 30-36: In the rtl_rx empty-slot branch, schedule a ring reset with
the existing RTL_FLAG_TASK_RESET_PENDING task before breaking, so RX recovery
starts instead of leaving cur_rx stalled.

@patch/kernel/archive/realtek-rtd129x-7.3/0056-PCI-rtd139x-add-the-RTD1395-PCIe-host-controller.patch:
- Around line 141-144: Reduce RTD_CFG_RD_TIMEOUT_US to a low-millisecond timeout
so config reads do not busy-wait under pci_lock with IRQs disabled for up to one
second per attempt. Keep the change scoped to the read timeout; leave
RTD_CFG_WR_TIMEOUT_US and RTD_DLLP_RETRIES unchanged.
- Line 322: Align the address in the config write path before writing it to
RTD_CFG_ADDR, clearing bits [1:0] to match the config read path and ensure
sub-dword writes target the correct bytes.

Keep the RTD1296 audio firmware in the repository. The build no longer downloads it. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>
Move U-Boot from v2026.10-rc5 to the v2026.10 release. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>
Add RTD1395 support to the current and edge kernels. The BPI-M4 gets SD card, eMMC, Ethernet, USB, CPU frequency scaling, thermal throttling, an HDMI console and HDMI audio. Fixes shared with the BPI-W2: - USB 2.0 PHY: use the correct register for the second port. - r8169soc: report the link speed on the first ethtool read. - r8169soc: reset the RX ring at a slot without a buffer. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>
Enable the M.2 Key E PCIe slot on the BPI-M4. The link trains at Gen1 x1. Gen2 also trains, but stays off. The CPU window is 120 KiB. Devices with a larger BAR do not get it. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>
Add the RTD1395 and the BPI-M4 to U-Boot. U-Boot starts the audio firmware and opens the eMMC controller to Linux. The BPI-M4 gets the Ethernet LEDs and a fixed MAC address. U-Boot probes the DRAM size: the vendor loader reports 2 GiB on 1 GiB boards. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>
The RTD1395 SPI loader cannot read U-Boot raw from the eMMC. It loads U-Boot from FAT partition 1. Add that partition on eMMC installs and keep U-Boot in it. RTD1295/RTD1296 boards keep the eMMC boot area. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>
Add the BPI-M4 board config and the RTD1395 audio firmware. The BPI-M4 boots the current and edge kernels from SD card or eMMC. Assisted-by: Claude Opus 5.5 Signed-off-by: Igor Pecovnik <igor@armbian.com>

Add the Banana Pi BPI-M4 (Realtek RTD1395) to the
realtek-rtd129xfamily. It boots mainline U-Boot v2026.10 (release) and the current (6.18) and edge (7.3) kernels.Works:
armbian-installinstalls to it, and the board boots from it.simple-framebuffer.Fixes:
ethtoolreported an unknown speed on its first read after a link change (latched BMSR link status). Shared with the W2.Not working yet:
mt7925ecannot map its 2 MiB BAR. Realtek Wi-Fi and RTL8125 cards have small BARs and should fit.Shared family code: the patches touch drivers and the family config that the BPI-W2 also uses. W2 behaviour is meant to stay the same. W2 builds (current and edge DTBs) pass, but the W2 is not retested on hardware.
Tested boards: Banana Pi BPI-M4 (1 GiB).
