apalis-tk1: fix pcie reset for reliable gigabit ethernet operationIt turns out that the current PCIe reset implementation in the PCIeboard init function is not quite working reliably due to PCIe resettiming violations. Fix this by overriding thetegra_pcie_board_port_reset() function.Also allow optionally bringing up the PCIe switch as found on the ApalisEvaluation board. Note however that the Apalis PCIe port is also leftdisabled in the device tree by default.Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>Signed-off-by: Tom Warren <twarren@nvidia.com>

SPDX: Convert all of our single license tags to Linux Kernel styleWhen U-Boot started using SPDX tags we were among the early adopters andthere weren't a lot of other examples to borrow from. So we picked thearea of the file that usually had a full license text and replaced itwith an appropriate SPDX-License-Identifier: entry. Since then, theLinux Kernel has adopted SPDX tags and they place it as the very firstline in a file (except where shebangs are used, then it's second line)and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibilityand in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declaredlicense in the tag as both the before and after are identical in tagcontents. There's also a few places where I found we did not have a tagand have introduced one.Signed-off-by: Tom Rini <trini@konsulko.com>

Theregulator and GPIO functions are now handled by separate drivers.Update nyan-big to work correct. Three boards will need to be updated bythe maintainers: apalis-tk1, cei-tk1-som.

arm: tegra: initial support for apalis tk1This patch adds board support for the Toradex Apalis TK1 a computer onmodule which can be used on different carrier boards.The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3LRAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensorchip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec.Furthermore, there is a Kinetis MK20DN512 companion micro controller foranalogue, CAN and resistive touch functionality.For the sake of ease of use we do not distinguish between differentcarrier boards for now as the base module features are deemedsufficient enough for regular booting.The following functionality is working so far:- eMMC boot, environment storage and Toradex factory config block- Gigabit Ethernet- MMC/SD cards (both MMC1 as well as SD1 slot)- USB client/host (dual role OTG port as client e.g. for DFU/UMS or host, other two ports as host)Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>Reviewed-by: Simon Glass <sjg@chromium.org>Signed-off-by: Marcel Ziswiler <marcel@ziswiler.com>Signed-off-by: Tom Warren <twarren@nvidia.com>
