Hi folks,

I installed redboot on my custom SA1110 board, but get totally wrong
values about the available RAM and FLASH.
Where are the variables "user_ram_start" (redboot/main.c),
"user_ram_end" (redboot/main.c), "blocks" (redboot/flash.c) and
"block_size" (redboot/flash.c) defined?
I'm grepping like mad but can't find them.
I'm using the eCos-CVS version of last week.

It's defined in a somewhat eccentric way: in redboot.h they are defined
with EXTERN. main.c defines DEFINE_VARS though (see further up redboot.h
for the definition of EXTERN).

Well, it may _seem_ eccentric, but it is more maintainable as all the
configury is in one place, not two.
