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> |

Overview
--------
QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
development platform, with a complete debugging environment.
The LS1012ARDB board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.
LS1012A SoC Overview
--------------------
Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A
SoC overview.
LS1012ARDB board Overview
-----------------------
- SERDES Connections, 4 lanes supporting:
- PCI Express - 3.0
- SGMII, SGMII 2.5
- SATA 3.0
- DDR Controller
- 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s
-QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select
signals to
- QSPI NOR flash memory (2 virtual banks)
- the QSPI emulator.s
- USB 3.0
- one high-speed USB 2.0/3.0 port.
- Two enhanced secure digital host controllers:
- SDHC1 controller can be connected to onboard SDHC connector
- SDHC2 controller: Three dual 1:4 mux/demux devices,
74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC,
SDIO WiFi, SPI, and Ardiuno shield
- 2 I2C controllers
- One SATA onboard connectors
- UART
- The LS1012A processor consists of two UART controllers,
out of which only UART1 is used on RDB.
- ARM JTAG support
Booting Options
---------------
a) QSPI Flash Emu Boot
b) QSPI Flash 1

Major Difference between LS1012ARDB and LS1012A-2G5RDB
------------------------------------------------------
1. LS1012A-2G5RDB has Type C USB connector unlike USB Type A/B of LS1012ARDB
2. LS1012A-2G5RDB has 2 2.5G AQR PHY unlike 2 1G Realtek RTL8211FS PHYs
of LS1012ARDB
3. LS1012A-2G5RDB is not having Arduino header
4. LS1012A-2G5RDB doesn't have PCI slot
