- * Turn off (reset/disable) SDMMC1 on Nano here, before GPIO INIT.
- * We do this because earlier bootloaders have enabled power to
- * SDMMC1 on Nano, and toggling power-gpio (PZ3) in pinmux_init()
- * 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.

+U-Boot for the LG Optimus 2X P990
+=================================
+
+``DISCLAMER!`` Moving your device to use U-Boot assumes replacement of the
+vendor bootloader. Vendor Android firmwares will no longer be able to run on
+the device. This replacement IS reversible.
+
+Quick Start
+-----------
+
+- Build U-Boot
+- Process U-Boot
+- Flashing U-Boot into the eMMC
+- Boot
+- Self Upgrading
+
+Build U-Boot
+------------
+
+.. code-block:: bash
+
+ $ export CROSS_COMPILE=arm-none-eabi-
+ $ make star_defconfig
+ $ make
+
+After the build succeeds, you will obtain the final ``u-boot-dtb-tegra.bin``
+image, ready for further processing.
+
+Process U-Boot
+--------------
+
+``DISCLAMER!`` All questions related to the re-crypt work should be asked
+in re-crypt repo issues. NOT HERE!
+
+re-crypt is a tool that processes the ``u-boot-dtb-tegra.bin`` binary into form
+usable by device. This process is required only on the first installation or
+to recover the device in case of a failed update.
+
+Permanent installation can be performed either by using the nv3p protocol or by
+pre-loading just built U-Boot into RAM.
+
+Processing for the NV3P protocol
+********************************
+
+.. code-block:: bash
+
+ $ git clone https://gitlab.com/grate-driver/re-crypt.git
+ $ cd re-crypt # place your u-boot-dtb-tegra.bin here
+ $ ./re-crypt.py --dev star
+
+The script will produce a ``repart-block.bin`` ready to flash.
+
+Processing for pre-loaded U-Boot
+********************************
+
+The procedure is the same, but the ``--split`` argument is used with the
+``re-crypt.py``. The script will produce ``bct.img`` and ``ebt.img`` ready
+to flash.
+
+Flashing U-Boot into the eMMC
+-----------------------------
+
+``DISCLAMER!`` All questions related to NvFlash should be asked in the proper
+place. NOT HERE! Flashing U-Boot will erase all eMMC, so make a backup before!
+
+Permanent installation can be performed either by using the nv3p protocol or by
+pre-loading just built U-Boot into RAM.
+
+Flashing with the NV3P protocol
+*******************************
+
+Nv3p is a custom Nvidia protocol used to recover bricked devices. Devices can
+enter it by pre-loading vendor bootloader with nvflash.
+
+With nv3p, ``repart-block.bin`` is used. It contains BCT and a bootloader in
+encrypted state in form, which can just be written RAW at the start of eMMC.
+
+.. code-block:: bash
+
+ $ ./nvflash_v1.13.87205 --bct star.bct --setbct --odmdata 0xC8000
+ --configfile flash.cfg --bl android_bootloader.bin --sync
+ $ ./utiils/nvflash_v1.13.87205 --resume --rawdevicewrite 0 2048 repart-block.bin
+
+When flashing is done, reboot the device.
+
+Flashing with a pre-loaded U-Boot
+*********************************
+
+U-Boot pre-loaded into RAM acts the same as when it was booted "cold". Currently
+U-Boot supports bootmenu entry fastboot, which allows to write a processed copy
+of U-Boot permanently into eMMC.
+
+While pre-loading U-Boot, hold the ``volume down`` button which will trigger
+the bootmenu. There, select ``fastboot`` using the volume and power buttons.
+After, on host PC, do:
+
+.. code-block:: bash
+
+ $ fastboot flash 0.1 bct.img
+ $ fastboot flash 0.2 ebt.img
+ $ fastboot reboot
+
+Device will reboot.
+
+Boot
+----
+
+To boot Linux, U-Boot will look for an ``extlinux.conf`` on MicroSD and then on
+eMMC. Additionally, if the Volume Down button is pressed while booting, the
+device will enter bootmenu. Bootmenu contains entries to mount MicroSD and eMMC
+as mass storage, fastboot, reboot, reboot RCM, poweroff, enter U-Boot console
+and update bootloader (check the next chapter).
+
+Flashing ``repart-block.bin`` eliminates vendor restrictions on eMMC and allows
+the user to use/partition it in any way the user desires.
+
+Self Upgrading
+--------------
+
+Place your ``u-boot-dtb-tegra.bin`` on the first partition of the MicroSD card
+and insert it into the device. Enter bootmenu, choose update the bootloader
+option with the Power button and U-Boot should update itself. Once the process
+is completed, U-Boot will ask to press any button to reboot.
