ramips: add support for Widora Neo 32MB flash revision Widora has updated their Widora Neo board recently. The new model uses 32MB WSON-8 factor SPI flash instead of the original 16MB SOP-8 factor SPI flash. All the other hardware components are the same as the first revision. Detailed hardware specs listed below: CPU: MTK MT7688AN RAM: 128MB DDR2 ROM: 32MB WSON-8 factor SPI Flash (Winbond) WiFi: Built-in 802.11n 150Mbps? Ethernet: 10/100Mbps x1 Audio codec: WM8960 Other IO: USB OTG; USB Power+Serial (CP2104); 3x LEDs (Power, LAN, WiFi); 2x Keys (WPS, CPU Reset) 1x Audio In/Out 1x IPEX antenna port 1x Micro SD slot Signed-off-by: Jackson Ming Hu <huming2207@gmail.com> Signed-off-by: Mathias Kresin <dev@kresin.me> 2018-01-08 05:27:28 +00:00

ramips: fix reboot for remaining 32 MB boards The following devices have a Winbond W25Q256FV flash chip, which does not have the RESET pin enabled by default, and otherwise would require setting a bit in a status register. Before moving to Linux 5.4, we had the patch: 0053-mtd-spi-nor-add-w25q256-3b-mode-switch.patch which kept specific flash chips with explicit 3-byte and 4-byte address modes to stay in 3-byte address mode while idle (after an erase or write) by using a custom flag SPI_NOR_4B_READ_OP that was part of the patch. this was obsoleted by the patch: 481-mtd-spi-nor-rework-broken-flash-reset-support.patch which uses the newer upstream flag SNOR_F_BROKEN_RESET for devices with a flash chip that cannot be hardware reset with RESET pin and therefore must be left in 3-byte address mode when idle. The new patch requires that the DTS of affected devices have the property "broken-flash-reset", which was not yet added for most of them. This commit adds the property for remaining affected devices in ramips target, specifically because of the flash chip model. However, it is possible that there are other devices where the flash chip uses an explicit 4-byte address mode and the RESET pin is not connected to the SOC on the board, and those DTS would also need this property.

ramips: convert most mtd-mac-address cases in DTSI to nvmem Convert most of the cases from mtd-mac-address to nvmem where MAC addresses are set in the DTSI, but the partitions are only located in the device DTS. This posed some problems earlier, since in these cases we are using partitions before they are defined, and the nvmem system did not seem to like that. There have been a few different resolution approaches, based on the different tradeoffs of deduplication vs. maintainability: 1. In many cases, the partition tables were identical except for the firmware partition size, and the firmware partition was the last in the table. In these cases, the partition table has been moved to the DTSI, and only the firmware partition's "reg" property has been kept in the DTS files. So, the updated nvmem definition could stay in the DTSI files as well. 2. For all other cases, splitting up the partition table would have introduced additional complexity. Thus, the nodes to be converted to nvmem have been moved to the DTS files where the partitioning was defined. 3. For Netgear EX2700 and WN3000RP v3, the remaining DTSI file was completely dissolved, as it was quite small and the name was not really nice either. 4. The D-Link DIR-853 A3 was converted to nvmem as well, though it is just a plain DTS file not taken care of in the first wave. In addition, some minor rearrangements have been made for tidyness. Not covered (yet) by this patch are: * Various unielec devices * The D-Link DIR-8xx family Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> 2021-08-17 18:53:27 +00:00			`&firmware {`
