ARM: tegra: Add NVIDIA Jetson Nano Developer Kit support
The Jetson Nano Developer Kit is a Tegra X1-based development board. It is similar to Jetson TX1 but it is not pin compatible. It features 4GB of LPDDR4, a SPI NOR flash for early boot firmware and an SD card slot used for storage. HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0 and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI Ethernet controller provides onboard network connectivity. NVMe support has also been added. Env save is at the end of QSPI (4MB-8K). A 40-pin header on the board can be used to extend the capabilities and exposed interfaces of the Jetson Nano.

* 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.
