2023-01-20global: Finish CONFIG -> CFG migrationTom Rini1-4/+4
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

2021-09-23arm: mediatek: merge board Kconfigs into mach-mediatekGuillaume La Roque3-2/+18
On MediaTek boards we cannot override the SYS_BOARD / SYS_CONFIG_NAME variables from defconfig. This is because in board/mediatek/mtXXXX/Kconfig this value was override by default due to the if CONFIG_TARGET_MTXXXX condition. Merge all the Kconfigs to the mach-medatek/Kconfig.

2020-04-27mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementationsStefan Roese1-18/+10
The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

This patch adds SPL support for mtmips platform. The lowlevel architecture is split into SPL and the rest parts are built into a memory loadable u-boot image. Optional SPL_DM and OF_CONTROL are also supported. The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are not enabled and the memory bootable u-boot (u-boot.img) is generated automatically so there is not need to add a separate config for it. A lzma compressed payload (u-boot-lzma.img) is also generated and it will be combined with u-boot-spl.bin to form the unified ROM bootable binary u-boot-mtmips.bin.

2019-07-05mips: mt76xx: Implement new d-cache fix in last_stage_init()Stefan Roese1-0/+26
With commit 06985289d452 ("watchdog: Implement generic watchdog_reset() version") the init sequence has changed in arch_misc_init(), resulting in a re-appearance of the d-cache issue on MT7688 boards (e.g. gardena). When this happens, the first (or sometimes later ones as well) TFTP command hangs and does not complete correctly. This leads to the assumption that the d-cache is not in a clean state once the ethernet driver is called (d-cache is used here for the buffers). The old work- around with the cache flush somehow does not work any more now with the new code change. Unfortunately adding CONFIG_SYS_MALLOC_CLEAR_ON_INIT also did not fix this issue. With v2019.07-rc3 it shows again. The time of accessing the data seems to be very important here. It needs to be "very late" in the boot process. Testing has shown, that copying a 64KiB area in DDR at a very late bootup time, directly before calling into the prompt, fixes this issue. Flushing of the complete d-cache does not seem to necessary, as this copy alone seems to fix this problem.
