This is long over due. All but two net drivers have been converted, but those have now been dropped. The only thing left to do is actually delete all references to NET_MULTI and code that is compiled when that is not defined. So here we scrub the core code.

2. 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
|
|
