riscv: dts: starfive: jh7110: More U-Boot downstream changes for JH7110
v2 cover riscv: dts: starfive: jh7110: More U-Boot downstream changes for JH7110
Bring in additional downstream U-Boot boot loader changes for StarFive VisionFive2 board target (and related JH7110 common boards). Create a basic dt-binding (and not any Linux driver) in support of the memory-controller dts node used in mainline U-Boot. Also add bootph-pre-ram hinting to jh7110.dtsi needed at SPL boot phase.
Changes since v1:
- patch 1/3 "add StarFive JH7110 SoC DMC": Rephrase commit message and description, drop min/max items and list with description instead, drop legacy clock-frequency property.
- patch 2/3 "add memory controller node": Rephrase commit message and drop clock-frequency property.

Best regards,
HalWhat users are there for 'pllclk' at U-Boot SPL phase? There does not seem to be any difference in testing U-Boot and Linux with or without this hint for 'pllclk'.

I see commit
8b3f2eb7d8912204bda2d914b8a9a1ce1c31bb5cadding this line to solve some problems.
Yes, there was some mistake in how I am testing U-Boot SPL. Given that (U-Boot code base) jh7110-u-boot.dtsi override is replaced with contents:
/ {
soc {
memory-controller@15700000 {
clock-frequency = <2133>; /* starfive_ddr.c
driver needs update to use common clocks */
};
};
};&syscrg {
assigned-clock-rates = <0>; /* cpufreq not implemented, use
defaults */
};
I am now able to reproduce this boot failure in U-Boot SPL on Star64.
Additionally, U-Boot SPL fails to boot if 'gmac1_rgmii_rxin' or 'gmac1_rmii_refin' are missing bootph-pre-ram hint, as a dependency of syscrg. It is okay to omit hints for 'gmac0_rgmii_rxin' and 'gmac0_rmii_refin' as the dependency of aoncrg not used at U-Boot SPL.
In the next version of this series will be added bootph-pre-ram hints for syscrg dependencies: 'pllclk', 'gmac1_rgmii_rxin', and 'gmac1_rmii_refin'
Thank you, Hal.
