[参考译文] AM62P：SDK 10.1：dmesg 打印有关 RTC 时钟速率不正确的错误信息

事实证明我在 u-boot spl_board_init ()中缺少32K 时钟命令。  在 u-boot 2023中、它们被移至 board/ti/common/rtc.c、但在 u-boot 2024中、它们似乎被移回单个 AM62*板级配置文件。

	/* We have 32k crystal, so lets enable it */
	val = readl(MCU_CTRL_LFXOSC_CTRL);
	val &= ~(MCU_CTRL_LFXOSC_32K_DISABLE_VAL);
	writel(val, MCU_CTRL_LFXOSC_CTRL);
	/* Add any TRIM needed for the crystal here.. */
	/* Make sure to mux up to take the SoC 32k from the crystal */
	writel(MCU_CTRL_DEVICE_CLKOUT_LFOSC_SELECT_VAL,
	       MCU_CTRL_DEVICE_CLKOUT_32K_CTRL);
