[U-Boot] question about example/standalone/mips.lds

Hi

sorry I misunderstand something. I download the ppc-2008-04-01.iso
and run "./MAKEALL" without any argument. that why it compile 300+ boards.
I should read MAKEALL more carefully.

now I am downloading "mips-2007-01-21.iso".

my board is mips EL system.
is that mean when I run "MAKEALL" I just need add mips_el?? like this one[1]

another question:
I found this in "MAKEALL":
LIST_au1xx0_el="        \
         dbau1550_el     \
         pb1000          \
"
it shows that those two boards are Endianess Little System
but in board/pb1x00/u-boot.lds , board/dbau1x00/u-boot.lds line:27[2]
show that those two boards are both BE system?
is there something wrong or I misunderstand something

thanks for all your reply.
