ath79: GL-AR300M: provide NAND support; increase to 4 MB kernel The GL.iNet GL-AR300M has been supported by the ar71xx and ath79 platforms with access to its 16 MB NOR flash, but not its 128 MB SPI NAND flash. This commit provides support for the NAND through the upstream SPI-NAND framework. Devices with both NOR and NAND flash can support independent firmware on each, with U-Boot able to boot from either. The OEM U-Boot will fall back to the NOR firmware after three "unsuccessful" boots. The family of GL-AR300M devices on the ath79 platform now includes: * glinet,gl-ar300m-lite "generic" target, NOR-only board * glinet,gl-ar300m-nand "nand" target * glinet,gl-ar300m-nor "nand" target (NAND-aware) NB: This commit increases the kernel size from 2 MB to 4 MB "Force-less" sysupgrade is presently supported from the current versions of following NOR-based firmwre images to the version of glinet,gl-ar300m-nor firmware produced by this commit: * gl-ar300m -- OEM v3 NOR ar71xx (openwrt-ar300m16-*.bin) * gl-ar300m -- OpenWrt 18.06 ar71xx * gl-ar300m -- OpenWrt 19.07 ar71xx Other upgrades to these images should be performed through U-Boot. The GL-AR300M OEM U-Boot allows upload and flashing of either NOR firmware (sysupgrade.bin) or NAND firmware (factory.img) through its HTTP-based GUI. Serial connectivity is not required. The glinet,gl-ar300m-nand and glinet,gl-ar300m-nor images generated after this commit should safely flash each other using sysupgrade. The boot counter is implemented by the OEM using u-boot-env. At this time, it does not appear that the switch on the side of the unit can be used to select NOR vs. NAND boot and the fail-over is only from NAND to NOR. To save flash wear, it is only reset when running the glinet,gl-ar300m-nand firmware. NAND-specific base-files are used to remove impact on existing generic and tiny targets. As there is now no "generic" build appropriate for the GL-AR300M16, (or for users of the GL-AR300M that do not need access to NAND) it will be introduced in a subsequent commit. Note: `mtd_get_mac_binary art 0x6` does not return the proper MAC and the GL.iNet source indicates that only the 0x0 offset is valid The ar71xx targets are unmodified.

ath79: remove model name from LED labels Currently, we request LED labels in OpenWrt to follow the scheme modelname:color:function However, specifying the modelname at the beginning is actually entirely useless for the devices we support in OpenWrt. On the contrary, having this part actually introduces inconvenience in several aspects: - We need to ensure/check consistency with the DTS compatible - We have various exceptions where not the model name is used, but the vendor name (like tp-link), which is hard to track and justify even for core-developers - Having model-based components will not allow to share identical LED definitions in DTSI files - The inconsistency in what's used for the model part complicates several scripts, e.g. board.d/01_leds or LED migrations from ar71xx where this was even more messy Apart from our needs, upstream has deprecated the label property entirely and introduced new properties to specify color and function properties separately. However, the implementation does not appear to be ready and probably won't become ready and/or match our requirements in the foreseeable future. However, the limitation of generic LEDs to color and function properties follows the same idea pointed out above. Generic LEDs will get names like "green:status" or "red:indicator" then, and if a "devicename" is prepended, it will be the one of an internal device, like "phy1:amber:status". With this patch, we move into the same direction, and just drop the boardname from the LED labels. This allows to consolidate a few definitions in DTSI files (will be much more on ramips), and to drop a few migrations compared to ar71xx that just changed the boardname. But mainly, it will liberate us from a completely useless subject to take care of for device support review and maintenance. To also drop the boardname from existing configurations, a simple migration routine is added unconditionally. Although this seems unfamiliar at first look, a quick check in kernel for the arm/arm64 dts files revealed that while 1033 lines have labels with three parts *:*:*, still 284 actually use a two-part labelling *:*, and thus is also acceptable and not even rare there.
