When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line 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 visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

Hardware ======== The PDU-001 (Processor and Display Unit) is a plugin card for 19" racks. It is manufactured by EETS GmbH (https://www.eets.ch). The core of the board is a m2 SOM from bytes at work (https://www.bytesatwork.ch) which in turn is based on AM3352 SOC from TI (http://www.ti.com). Customization ============= As usual the console serial interface is set by CONFIG_CONS_INDEX. Best choice is 4 here since UART3 is wired to the connector K2. The Run LED on the PDU-001 can be turned on red by setting CONFIG_RUN_LED_RED or green by setting CONFIG_RUN_LED_GREEN. Setting CONFIG_RUN_LED_OFF will turn off the Run LED. Booting ======= The system boots from either eMMC or SD card cage. It will first try to boot from the SD card cage. If this fails (missing or unbootable SD card) it will try to boot from the internal eMMC. The root file system is always expected to be located in the second partition of the device (eMMC or SD card) that pro- vided the boot loader.
