hi,all
I am trying to port eCos on "AR2001" platform.I wonder whether or not anybody else is already working on something similar.
The Architectural Overview of AR2001:

32 thirty-two bits general purpose registers
4KB two-way set-associative instruction cache, 2KB direct mapped data cache.
Up to 100 MHz CPU bus frequency
SDRAM Controller
Supports two SDRAM banks of either 16 or 32 bit wide data bus
Supports 16Mb (1Mx16, 2Mx8) , 64Mb (2Mx32, 4Mx16, 8Mx8) and 128Mb
(4Mx32, 8Mx16) type SDRAM
2MB up to 64MB total address space
Active power down and self refresh power saving modes
…………
Among the present hal packages,which is most similar to "AR2001"?
