[PATCH 3/5] aspeed: Add a DRAM memory region at the SoC level |
Date: |
Wed, 16 Oct 2019 10:50:33 +0200 |
Currently, we link the DRAM memory region to the FMC model (for DMAs)
through a property alias at the SoC level. The I2C model will need a
similar region for DMA support, add a DRAM region property at the SoC
level for both model to use.
