The way that we use this file currently means that we have to guard it in every platform Kconfig. But it is also required in all NXP platforms, including non-reference platforms. Make all options in it have appropriate dependencies so that we can include it a single time under arch/Kconfig 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
c) QSPI Flash 2

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
