Subject: [PATCH 0/5] *** phyCORE-AM62x: DDR detection / Inject DDR timing deltas ***
Date: Tue, 7 May 2024 17:17:52 +0200 [thread overview]
Message-ID: <20240507151757.1202825-1-w.egorov@phytec.de> (raw)
PHYTEC stores details about the hardware in an EEPROM on the SoM. We can
utilize this information and chose the proper DDR timings accordingly.
Due to the limited SRAM memory on the AM62x, the concept was to store
only the DDR timings deltas and not their full set, see Patch 4 & 5.
The last patch adds support for a 1 GB and 4 GB RAM variant of the
phyCORE-AM62x.
Patch 4 & 5 are based on
https://patchwork.ozlabs.org/project/uboot/list/?series=404273
Wadim Egorov (5):
board: phytec: Make AM6 SoM detection depend on I2C
board: phytec: Fix function definitions in AM6x SOM detection
arm: mach-k3: am625: Call do_board_detect() before DDR probing
board: phytec: common: Introduce a method to inject DDR timings deltas
board: phytec: am62x: Add support for 1 & 4 GB RAM variants
