Add support for the Cudy P5, an IPQ5018 cellular router. Specifications: - SoC: Qualcomm IPQ5018 - RAM: 256 MiB - Flash: 128 MiB ESMT F50D1G41LB SPI-NAND - Wi-Fi: IPQ5018 2.4 GHz and QCN6122 5 GHz - Ethernet: 3 LAN ports, 1 WAN port through QCA8337 - Modem: M.2 USB and PCIe - LEDs: six - Buttons: reset and WPS - UART: 115200 8n1 (1.8 V, GND, RX, TX) Stock QSDK reports the flash as GigaDevice because ESMT uses GigaDevice's 0xc8 manufacturer ID on this family. Keep the Cudy calibration data for both radios. Use ath_bdf_tool to patch QCN6122 byte 0x45c from 0x03 to 0x00 and update its internal checksum. Refresh the embedded regdb in both BDF files from Qualcomm WLAN.HK.2.7.0.1 build 01744. The Cudy BDF files have no fixed regulatory domain to remove. This branch carries the following Linux 6.18 dependencies and experiments: - Local patch 999 applies Ziyang Huang's five reduced ath11k ring values. This temporary fallback changes the shared ath11k build. Remove it when OpenWrt has a working selectable or runtime low-memory profile. - Mark Ruvald Pedersen's private RXDMA page-frag caches reduce retained pages caused by mixed allocation lifetimes. - Stanislaw Pal's QPIC SET_FEATURE fix prevents OTP-mode failures. - Stanislaw Pal's current CMN PLL fix prevents the IPQ5018 boot hang. - Md Sadre Alam's QPIC x4 series enables quad cache reads and program loads. A local fallback initializes PROGRAM_EXECUTE unconditionally. The operation has no data phase and uses an x1 command and address. The PR 21495 package graph caused recursive ath11k AHB and PCI dependencies in this tree. An earlier duplicate AHB variant built without passing the small-buffer definition to ath11k. Patch 999 keeps the proven values while the package integration remains unfinished. The IPQ5018 USB3 backport failed P5 hardware testing. xHCI started, but the RM551 stayed on USB2 and repeatedly failed enumeration with error -71. ECM attachment and DHCP were unreliable. Keep the tested USB2 layout. Tested and working: - The board boots with the P5 DTS and CMN PLL fix. - MAC addresses and Wi-Fi calibration data are extracted correctly. - LAN uses GMAC1 through UNIPHY0, SGMII, and QCA8337 port 6. - WAN uses GMAC0 through the internal GE PHY and QCA8337 port 5. - Both radios start with the checksum-corrected Cudy board data. - The updated regdb raises both radio power limits by 2 dBm. - The RM551 works in USB2 ECM mode. - GPIO30 is modem-reset. A rising edge restarts the RM551. - The BOOTCONFIG-aware sysupgrade path is included. Base MAC is read directly from the `bdinfo` MTD. RM551 PCIe mode does not enumerate an endpoint yet. Installation: 1. Back up all stock partitions. 2. Load the initramfs image through TFTP and boot it from RAM. 3. Check NAND, Ethernet, Wi-Fi, USB, and BOOTCONFIG. 4. Run sysupgrade only after the hardware checks pass.
