SPDX: Convert all of our single license tags to Linux Kernel style 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>

powerpc/mpc85xx: Add BSC9132/BSC9232 processor support The BSC9132 is a highly integrated device that targets the evolving Microcell, Picocell, and Enterprise-Femto base station market subsegments. The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850 core technologies with MAPLE-B2P baseband acceleration processing elements to address the need for a high performance, low cost, integrated solution that handles all required processing layers without the need for an external device except for an RF transceiver or, in a Micro base station configuration, a host device that handles the L3/L4 and handover between sectors. The BSC9132 SoC includes the following function and features: - Power Architecture subsystem including two e500 processors with 512-Kbyte shared L2 cache - Two StarCore SC3850 DSP subsystems, each with a 512-Kbyte private L2 cache - 32 Kbyte of shared M3 memory - The Multi Accelerator Platform Engine for Pico BaseStation Baseband Processing (MAPLE-B2P) - Two DDR3/3L memory interfaces with 32-bit data width (40 bits including ECC), up to 1333 MHz data rate - Dedicated security engine featuring trusted boot - Two DMA controllers - OCNDMA with four bidirectional channels - SysDMA with sixteen bidirectional channels - Interfaces - Four-lane SerDes PHY - PCI Express controller complies with the PEX Specification-Rev 2.0 - Two Common Public Radio Interface (CPRI) controller lanes - High-speed USB 2.0 host and device controller with ULPI interface - Enhanced secure digital (SD/MMC) host controller (eSDHC) - Antenna interface controller (AIC), supporting four industry standard JESD207/four custom ADI RF interfaces - ADI lanes support both full duplex FDD support & half duplex TDD - Universal Subscriber Identity Module (USIM) interface that facilitates communication to SIM cards or Eurochip pre-paid phone cards - Two DUART, two eSPI, and two I2C controllers - Integrated Flash memory controller (IFC) - GPIO - Sixteen 32-bit timers Signed-off-by: Naveen Burmi <NaveenBurmi@freescale.com> Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
