19	SRAM0:	0x20010000-0x20017fff
20	SRAM1:	0x20000000-0x2000ffff
21	MBAR1:	0x10000000-0x4fffffff
22	MBAR2:	0x80000000-0xCfffffff
23	Flash:	0xffe00000-0xffffffff

965. COMPILER
97-----------
98To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture
99compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used.
100You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
101
102compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
