+Overview
+--------
+The LS1028A Reference Design (RDB) is a high-performance computing,
+evaluation, and development platform that supports ARM SoC LS1028A and its
+derivatives.

+
+LS1028ARDB board Overview
+-------------------------
+Processor
+ Two Arm Cortex- A72 processor cores:
+  - Based on 64-bit ARMv8 architecture
+  - Up to 1.3 GHz operation
+  - Single-threaded cores with 48 KB L1 instruction cache and 32 KB L1
+    data cache
+  - Arranged as a single cluster of two cores sharing a single 1 MB L2
+    cache
+DDR memory
+  - Five onboard 1G x8 discrete memory modules (Four data byte lanes
+    ECC)
+  - 32-bit data and 4-bit ECC
+  - One chip select
+  - Data transfer rates of up to 1.6 GT/s
+  - Single-bit error correction and double-bit error detection ECC (4-bit
+    check word across 32-bit data)
+High-speed serial ports(SerDes)
+ - Lane 0: Supports one 1 GbE RJ45 SGMII, connected through the
+   Qualcomm AR8033 PHY
+ - Lane 1: Supports four 1.25 GbE RJ45 QSGMII, each connected
+   through the NXP F104S8A PHY
+ - Lane 2: Connects to one PCIe M.2 Key-E slot to support PCIe Gen3
+   (8 Gbit/s) cards
+ - Lane 3: Connects to one PCIe M.2 Key-E slot or one SATA M.2 Key-B
+   slot through a register mux to support either PCIe Gen 3 (8 Gbit/s) or
+   SATA Gen 3 cards (6 Gbit/s) at a time
+eSDHC
+ - eSDHC1, eSDHC2
+SPI
+ - Connects to two mikroBUS sockets to support mikro-click modules,
+   such as Bluetooth 4.0, 2.4 GHz IEEE 802.15.4 radio transceiver, near
+   field communications (NFC) controller
+Octal SPI (XSPI)
+ - One 256 MB onboard XSPI serial NOR flash memory
+ - One 512 MB onboard XSPI serial NAND flash memory
+ - Supports a QSPI emulator for offboard QSPI emulation
+I2C
+ - All system devices are accessed via I2C1, which is multiplexed on
+   I2C multiplexer PCA9848 to isolate address conflicts and reduce
+   capacitive load
+ - I2C1 is used for EEPROMs, RTC, INA220 current-power sensor,
+   thermal monitor, PCIe/SATA M.2 connectors and mikro-click modules
+   1 and 2
+CAN
+ - The two CAN DB9 ports can support CAN FD fast phase at data rates of
+   up to 5 Mbit/s
+Serial audio interface(SAI)
+ - Audio codec SGTL5000 provides headphone and audio LINEOUT for
+   stereo speakers
+ - IEEE1588 interface to support audio on SAI4
