Hello!
After installing SDE toolkit onto Linux box I tried to compile the
YAMON bootloader source code (version of YAMON is 2.00). Few errors arised:
../arch/include/mips.h: Assembler messages:

make: *** [reset.o] Error1
The lines in mips.h that arise these warnings are the following:
// #define AU1000 0x00030100
//#define AU1000 0x01030200
//#define AU1000_2_1 0x00030200
It seems it doesn't understand the comment syntax.
I have installed the version 5.03.06-LITE of SDE. Following is the code
extract around which error occures:
#define t1 $9
#define mem_sdconfiga 0x0840
#define MEM_SDCONFIGA_DDR 0x9030060A
#define MEM_SDREFCFG_D_DDR MEM_SDCONFIGA_DDR
li t1, MEM_SDREFCFG_D_DDR
sw t1, mem_sdconfiga(t0)
sync
Compiler thinks 'li t1, MEM_SDREFCFG_D_DDR' is 'bad expression', may be
it guesses MEM_SDREFCFG_D_DDR is not defined correctly?
Thank you for every help in advance!

The original MIPS assembler used '#' as a comment character. Using
an ANSI style C preprocessor where preprocessor directives do not need
to be at the beginning of the line can can cause problems with files
using this type of comment. For this reason sde-gcc tells the
preprocessor to run in "traditional" mode which disables various ANSI
features. In particular, the preprocessor in traditional mode does not
accept '//' style comments.

If the '#define' was not at the beginning of the line the
preprocessor in traditional mode will ignore them and the assembler
would end up treating these lines as comments which would cause this error.
I've attached a patch that works on a MIPS release of the YAMON-2.00
sources to override the preprocessor mode for assembler files. See if it
helps...
