uboot_ddr1.c to U-Boot 2021.04 integration

[rudolfusselmann]

Hello,

We have configured our DDR4 with QCVS and generated the code for U-Boot.

However, we only could find AN5279 that explains the integration for an older U-Boot for LS2080. We are using LS1046A.

Are there any guides, as to how to integrate the DDR configuration with U-Boot 2021.4 ?

Has anyone done this and can offer some guidance?

Many Thanks,

rudi

In the recent released LSDK, we use ATF rather than using u-boot directly, DDR initialization is performed in ATF not in u-boot.

You could download LSDKUG_Rev21.08.pdf and refer to section "5.2.1.1 TF-A DDR Driver".

If you only use u-boot, you could still refer to AN5279.
