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> |

Freescale MPC837xE-RDB Board ----------------------------------------- 1. Board Description The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E, MPC8378E, and the MPC8379E processors in a Mini-ITX form factor. The MPC837xE-RDB's have the following common features: A) 256-MBytes on-board DDR2 unbuffered SDRAM B) 8-Mbytes NOR Flash C) 32-MBytes NAND Flash D) 1 Secure Digital High Speed Card (SDHC) Interface E) 1 Gigabit Ethernet F) 5-port Ethernet switch (Vitesse 7385) G) 1 32-bit, 3.3 V, PCI slot H) 1 32-bit, 3.3 V, Mini-PCI slot I) 4-port USB 2.0 Hub J) 1-port OTG USB K) 2 serial ports (top main console) L) on board Oscillator: 66M The MPC837xE-RDB's have the following differences: MPC8377E-RDB MPC8378E-RDB MPC8379E-RDB SATA controllers 2 0 4 PCI-Express (mini) 2 2 0 SGMII Ports 0 2 0 2. Memory Map 2.1. The memory map should look pretty much like this: Address Range Device Size Port Size (Bytes) (Bits) =========================== ================= ======= ========= 0x0000_0000 0x0fff_ffff DDR 256M 64 0x1000_0000 0x7fff_ffff Empty 1.75G - 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M 32 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M 32 0xe030_0000 0xe03f_ffff PCI I/O space 1M 32 0xe000_0000 0xe00f_ffff Int Mem Reg Space 1M - 0xe060_0000 0xe060_7fff NAND Flash 32K 8 0xfe00_0000 0xfe7f_ffff NOR Flash on CS0 8M 16 3.
