[ECOS] ixp2400/flash endian problem

[Aaron Richardson <aaron at planetrichardson dot net>]

I am trying to bring in the Intel code for the ixp2400 into the current 
version of redboot/ecos.  I am having problems getting the flash to work 
properly and I cannot track down the issue.  I am basically getting the data 
out of the flash in a swapped endian form.  I am using the current strata 
flash code.  I have commented out the device check code in the init routine 
and hard coded the correct values for now.  Here is what I get from fis:

RedBoot> fis list
Name              FLASH addr  Mem addr    Length      Entry point
BdeR              0x000000C4  0x00000000  0x00000400  0x00000000
tsySL me          0x0000FAC4  0x0000FAC4  0x00000200  0x00000000
BdeR toofnoc      0x00F0FDC4  0x00F0FDC4  0x00100000  0x00000000
 SIFeridrotc      0x0000FEC4  0x0000FEC4  0x00000200  0x00000000
bder-tookcab      0x000010C4  0x000010C4  0x00000400  0x00000000
RedBoot>

Intel is building with a compiler flag -mbig-endian and -D__ARMEB__.  If I 
compile with these settings (and use their swap image program) I get the 
output above.  However, If I remove both of these compiler options then I get 
the following:

RedBoot> fis list
Name              FLASH addr  Mem addr    Length      Entry point
RedBoot           0x000000C4  0x00000000  0x00000400  0x00000000
System Log        0x0000FAC4  0x0000FAC4  0x00000200  0x00000000
RedBoot config    0x00F0FDC4  0x00F0FDC4  0x00100000  0x00000000
FIS directory     0x0000FEC4  0x0000FEC4  0x00000200  0x00000000
redboot-backup    0x000010C4  0x000010C4  0x00000400  0x00000000

The names are not swapped any more, but the addresses are still munged.  Any 
ideas on how to fix this?

thanks,
