![]() 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> |

MEMORY MAP UNDER U-BOOT AND LINUX KERNEL =========================================== 2.1. System memory map: Flash: 0x00000000-0x3FFFFFFF (1024MB) DDR: 0x40000000-0x7FFFFFFF (1024MB) SRAM: 0x80000000-0x8FFFFFFF (256MB) IP: 0xFC000000-0xFFFFFFFF (256MB) 2.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and linux kernel, you can customize it based on your system requirements: Flash0: 0x00000000-0x00FFFFFF (16MB) DDR: 0x40000000-0x4FFFFFFF (256MB) SRAM: 0x80000000-0x80007FFF (32KB) IP: 0xFC000000-0xFC0FFFFF (64KB) 3. COMPILATION ============== 3.1 To create U-Boot the gcc-4.x-xx compiler set (ColdFire ELF or uClinux version) from codesourcery.com was used. Download it from: http://www.codesourcery.com/gnu_toolchains/coldfire/download.html 3.2 Compilation export CROSS_COMPILE=cross-compile-prefix cd u-boot make distclean make M53017EVB_config make 4.
