| * Note: The original firmware from Huawei can only boot 32-bit kernels. |
| * To boot arm64 kernels it is necessary to flash 64-bit TZ/HYP firmware |
| * with EDL, e.g. taken from the DragonBoard 410c. This works because Huawei |
| * forgot to set up (firmware) secure boot for some reason. |
| * |
| * Also note that Huawei no longer provides bootloader unlock codes. |
| * This can be bypassed by patching the bootloader from a custom HYP firmware, |

| * The Huawei device tree sets cd-gpios = <&msmgpio 38 GPIO_ACTIVE_HIGH>. |
| * However, gpio38 does not change its state when inserting/removing the |
| * SD card, it's just low all the time. The Huawei kernel seems to use |
| * polling for SD card detection instead. |
| * |
| * However, looking closer at the GPIO debug output it turns out that |
| * gpio56 switches its state when inserting/removing the SD card. |
| * It behaves just like gpio38 normally does. Usually GPIO56 is used as |
| * "UIM2_PRESENT", i.e. to check if a second SIM card is inserted. |
| * Maybe Huawei decided to replace the second SIM card slot with the |
| * SD card slot and forgot to re-route to gpio38. |
