/*
* 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,
* making it think the bootloader is unlocked.

/*
* 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.
