+ * results in power being back-driven into the SD-card and SDMMC1
+ * HW, which is 'bad' as per the HW team.
+ *
+ * From the HW team: "LDO2 from the PMIC has already been set to 3.3v in
+ * nvtboot/CBoot on Nano (for SD-card boot). So when U-Boot's GPIO_INIT
+ * table sets PZ3 to OUT0 as per the pinmux spreadsheet, it turns off
+ * the loadswitch. When PZ3 is 0 and not driving, essentially the SDCard
+ * voltage turns off. Since the SDCard voltage is no longer there, the
+ * SDMMC CLK/DAT lines are backdriving into what essentially is a
+ * powered-off SDCard, that's why the voltage drops from 3.3V to ~1.6V"
+ *
+ * Note that this can probably be removed when we change over to storing
+ * all BL components on QSPI on Nano, and U-Boot then becomes the first
+ * one to turn on SDMMC1 power. Another fix would be to have CBoot
+ * disable power/gate SDMMC1 off before handing off to U-Boot/kernel.
