What does PFE HIF_SOFT_RESET need on S32G399A-RDB3

(We are using our own operating system, not Linux)

We ported PFE FW 0.9.X like two years ago and it works fine on RDB2. But it seems not support S32G3. So I downloaded the latest s32g_pfe_*.fw file from version 1.5. But HIF initialization fails because of this “reset timed out” in pfeng_hw.c:

/* SOFT RESET */
writel(HIF_SOFT_RESET_CMD, base + HIF_SOFT_RESET);
while (readl(base + HIF_SOFT_RESET) & ~CSR_SW_RESET) {
    if (++ii < 1000u) {
        mdelay(1);
    } else {
        pr_err("HIF reset timed out.\n");
        return -ETIMEDOUT;
    }
}

I’ve configured the SIUL2, CGM, and clock of PFE-MAC2 (I don’t care about PFE-MAC0 and PFE-MAC1 for now. I just want PFE-MAC2 run on RGMII mode) and I don’t know what else I missed. My questions are:

What does HIF SOFT RESET require for it to succeed?
Do I have to configure the PFE-MAC0 and PFE-MAC1 as well even if they are not used?
Although the fw file is the latest, I’m still using our two-year-old PFE code to load it because the new ones in release/bsp35.0 is quite different and will need a lot of time to port to our RTOS. I’ve ported everything under the “on_g3” flag in the pfeng_hw.c. Is it OK?
