modification history
--------------------
01t,04mar99,cn   merge from ads860 release view, defaults to INCLUDE_END
		 (SPR# 23153).
01s,09feb99,cn   added macro NV_RAM_SIZE (SPR# 23387), also added support 
		 for SDRAM (SPR# 24337).
01r,18nov98,cn   END drivers are not selected for default.
01q,09nov98,cn   added support for 860T boards and FEC.
		 Changed ROM_SIZE to be 2Meg as in Makefile (SPR# 22572).
01p,08oct98,ms   made #define INCLUDE_CPM conditional on INCLUDE_NETWORK
01o,22jun98,cn   added support for Enhanced Network Driver.
01n,10jul98,sut  changed BSP_VERSION to "1.2" and BSP_REV to "/0"
                 added BSP_VER_1_2 macro ( Tornado 2.0 release ).
01m,28apr98,yp   added support for TFFS.
01l,08apr98,gls  BSP_REV level 3, for re-release to support FADS
01k,11nov97,map  added definitions for SYS_AUX_CLK [SPR# 9366].
01j,21feb97,mas  added undef of INCLUDE_TIMESTAMP (SPR 7879).
01i,03jan97,dat  BSP_REV level 2, for tornado 1.0.1 release
01h,12nov96,tam  added DEFAULT_POWER_MGT_MODE to select the default power
		 management mode.
01g,11nov96,tpr  turned the cache off when EDO dran selected.
01f,10nov96,tpr  defined cache and MMU support.
		 replaced SYS_CLK_FREQ by SPLL_FREQ_REQUESTED.
01e,08nov96,tpr  removed CPU_SPEED.
01d,06nov96,tpr  changed RAM_LOW_ADRS to 0x00010000.
01c,06nov96,tpr  increased BSP_REV from 0 to 1.
		 + added CLK macros.
01b,28may96,dzb  added Ethernet driver defines.
01a,19apr96,tpr  written.
