Subject: [RFC PATCH 0/5] Implement exiting 4-byte adressing mode before reset
Date: Tue, 7 May 2024 12:03:48 +0200 [thread overview]
Message-ID: <20240507100431.206670-1-robert.marko@sartura.hr> (raw)
This fixes the issue with 4-byte adressing mode being left enabled on
board reset.
That is an issue on Qualcomm IPQ4019 boards since the CPU expects flash
to be in 3-byte adressing mode and will just hang otherwise.
Note that this does not fix a case where you remove the power while U-Boot
is still running and in that case it will still be stuck in 4-byte mode.
Robert Marko (5):
dm: core: add on_reset method
dm: core: introduce uclass_id_on_reset()
mtd: spi-nor: rename and export 4-byte adressing mode function
mtd: spi: sf: implement .on_reset method
sysreset: call .on_reset for UCLASS_SPI_FLASH before reset request
