The updated sources bring support for the MT798x Filogic SoC family. Add builds for MT7986 with most supported storage types, each for DDR3 and DDR4 configurations. A better solution for skipping bad blocks on SPI-NAND connected via the SNFI interface has been implemented upstream, so drop local patch. Add pending patches [1] and [2] to fix boot on existing MT7622 boards. Tested on BananaPi BPi-R64 (SDMMC, eMMC, SPI-NAND), Linksys E8450 and Ubiquiti UniFi 6 LR as well as upcoming Bananapi BPi-R3 board for which support will be added in future patches.

Subject: [PATCH] mediatek: mt7622: initialize watchdog after DDR init
|
|
|
|
Initializing the WDT before memory calibration breaks reboot at least
|
|
on some MT7622 boards like the Bananapi BPi-R64:

ERROR: Cannot find any pass-window

ERROR: no DATLAT taps pass, DATLAT calibration fail!
|
|
ERROR: DATLAT calibration fail, write back to 20!
|
|
ERROR: EMI: complex R/W mem test failed: -2
|
|
|
|
Move watchdog initialization to happen only after memory initialization
|
|
has completed to avoid the problem.
