Description:

With Latest u-boot code checked-out (on 19th Feb 2007) from git, 
I got the following compilation errors, when configured for sc520_cdp board.

	1. sc520_cdp.c:33:initializer element is not constant
	2. cmd_bootm.c:470:1: directives may not be used inside a macro argument
		cmd_bootm.c:469:9: unterminated argument list 
		invoking macro "U_BOOT_CMD"
		cmd_bootm.c:477: parse error before ')' token
		
	3. video_bios.c:88: undefined reference to pci_find_class


I used gcc version 3.2.2.



DETAILS:


Error #1:  
==============================================================
REASON:
	For i386 architecture, Macro DECLARE _GLOBAL_DATA_PTR is defined 
as gd_t *gd = global_data in file "include/asm-i386/global_data.h",
here pointer gd is initialized to global_data which is a variable, 
defined in file "lib_i386/board.c". Global variable initialized 
with a non-constant expression is a compilation error.

FIX: 
	Redefined the macro DECLARE_ GLOBAL_DATA_PTR to gd_t *gd, removed
 the initialization part. gd is assigned to variable 'global_data' in
 start_i386boot() in lib_i386/board.c.  Definition of gd is protected
 by a macro _DEF_GLOBAL_PTR_, which is defined only in lib_i386/board.c



Error #2:
==============================================================
REASON:
directives may not be used inside a macro argument

FIX:
Repositioned the macro such that functionality is not changed and error is removed


Error #3: 
==============================================================
REASON:
In file lib_i386/video_bios.c, a function "pci_find_class" is called 
which is not defined in the u-boot code

FIX:
In u-boot code a function "pci_find_devices" is used to find the devices.
Instead of using function pci_find_class,function pci_find_devices can be 
used with appropriate vendor ID and device ID as input.
