ipq40xx: enable UBI size checks for some Linksys NAND devices

2023-11-26T17:37:21Z

Add correct NAND_SIZE in device definitions for EA6350v3, EA8300, MR8300, WHW01 and WHW03v2, to enable improved image size checks wrt UBI reserved blocks on NAND devices. Signed-off-by: Tony Ambardar

image: improve UBI image sizing on NAND devices

2023-11-26T17:37:20Z

Many NAND devices use a build recipe with "append-ubi | check-size" to ensure factory images don't exceed the target flash partition size. However, UBI reserves space for bad block handling and other operational overhead, and thus 'check-size' can overestimate the space available by several MB. In practice, this means a failed check is definitely a failure, while a passing check is only probably a pass. Improve the situation by teaching 'Build/append-ubi' to check image sizes while accounting for UBI reserved blocks. Add new device variable NAND_SIZE and use with existing IMAGE_SIZE to derate the available space. Each UBI device reserves 20 PEBs per 1024 PEBs of the entire NAND device for bad blocks, plus an additional 4 PEBs overhead. Many devices can transparently enable this check by setting NAND_SIZE based on their flash storage, and may then remove any unneeded 'check-size'.

image: fix Linksys image alignment and simplify footer creation

2023-11-26T17:37:20Z

Current factory image sizes for Linksys devices are 256-byte aligned. This is not an issue writing factory images from the OpenWrt or Linksys GUIs, but can lead to failures using a TFTP client from the Linksys bootloader: NAND write: device 1 offset 0x2800000, size 0xc00100 Attempt to write to non page aligned data NAND write to offset 2800000 failed -22 0 bytes written: ERROR Simplify Linksys footer creation by migrating to a makefile build recipe, and pre-pad the footer (with 0xFF) to ensure the final image is $(PAGESIZE) aligned. Finally, remove the old linksys-image.sh script no longer needed. Linksys footer details are given below for future reference. The 256-byte footer is appended to factory images and tested by both the Linksys Upgrader (observed in EA6350v3) and OpenWrt sysupgrade. Footer format: .LINKSYS. Checked by Linksys upgrader before continuing. (9 bytes) Upgrade version number, unchecked so arbitrary. (8 bytes) Model of device, space padded (0x20). (15 bytes) CRC checksum of factory image to flash. (8 bytes) Padding ('0' + 0x20 * 7) (8 bytes) Signature of signer, unchecked so arbitrary.

image: use helper function for size units

2023-11-26T17:37:20Z

Add the make function 'exp_units' for helping evaluate k/m/g size units in expressions, and use this to consistently replace many ad hoc substitutions like '$(subst k,* 1024,$(subst m, * 1024k,$(IMAGE_SIZE)))' in makefiles. Signed-off-by: Tony Ambardar

ipq40xx: fix typo in Linksys WHW01 image definition

ath79: add support for D-link DAP-1720 A1

2023-11-26T17:27:35Z

D-Link DAP-1720 rev A1 is a mains-powered AC1750 Wi-Fi range extender, manufactured by Alpha Networks [8WAPAC28.1A1G]. (in square brackets: PCB silkscreen markings) Specifications: * CPU (Qualcomm Atheros QCA9563-AL3A [U5]): 775 MHz single core MIPS 74Kc; * RAM (Winbond W9751G6KB-25J [U3]): 64 MiB DDR2; * ROM (Winbond W25Q128FV [U16]): 16 MiB SPI NOR flash; * Ethernet (AR8033-AL1A PHY [U1], no switch): 1 GbE RJ45 port (no PHY LEDs); * Wi-Fi * 2.4 GHz (Qualcomm Atheros QCA9563-AL3A [U5]): 3x3 802.11n; * 5 GHz (Qualcomm Atheros QCA9880-BR4A [U9]): 3x3 802.11ac Wave 1; * 3 foldable dual-band antennas (U.fl) [P1],[P2],[P3]; * GPIO LEDs: * RSSI low (red/green) [D2]; * RSSI medium (green) [D3]; * RSSI high (green) [D4]; * status (red/green) [D5]; * GPIO buttons: * WPS [SW1], co-located with status LED; * reset [SW4], accessible via hole in the side; * Serial/UART: Tx-Gnd-3v3-Rx [JP1], Tx is the square pin, 1.25mm pitch; 125000-8-n-1 in U-boot, 115200-8-n-1 in kernel; * Misc: * 12V VCC [JP2], fed from internal 12V/1A AC to DC converter; * on/off slide switch [SW2] (disconnects VCC mechanically); * unpopulated footprints for a Wi-Fi LED [D1]; * unpopulated footprints for a 4-pin 3-position slide switch (SW3); MAC addresses: * Label = LAN; * 2.4 GHz WiFi = LAN; * 5 GHz WiFi = LAN+2; Installation: * `factory.bin` can be used to install OpenWrt from OEM firmware via the standard upgrade webpage at http://192.168.0.50/UpdateFirmware.html * `recovery.bin` can be used to install OpenWrt (or revert to OEM firmware) from D-Link Web Recovery. To enter web recovery, keep reset button pressed and then power on the device. Reset button can be released when the red status LED is bright; it will then blink slowly. Set static IP to 192.168.0.10, navigate to http://192.168.0.50 and upload 'recovery.bin'. Note that in web recovery mode the device ignores ping and DHCP requests. Note: 802.11s is not supported by the default `ath10k` driver and firmware, but is supported by the non-CT driver and firmware variants. The `-smallbuffers` driver variant is recommended due to RAM size. Co-developed-by: Anthony Sepa Signed-off-by: Rani Hod
