Hi All,
I'd like to add STM entry for Juno based on Mathieu's patch [1]. But where can I find the STM base address and STM stimulus base address and their ranges.
Thanks, Chunyan

It's in the Juno Technical Reference Manual (TRM), see "Application processor memory map".
STM register base address = 0x20100000.
STM stimulus area = 0x28000000 to 0x28ffffff.

Hi Al,
Long time no see, thanks for your reply. STM on the Juno works well now. But I'm wondering why the size must be set 4K in DT rather than 64K, I noticed Juno TRM shows that STM Debug APB takes 64K.
Thanks, Chunyan

The APB interface is actually 4K. The DT should define them as 4K and the OS can map 4K pages to them and make the pages consecutive if it wants. They are 64K aligned in the physical address space because some OSes (or hypervisors etc.) want to use a minimum page size of 64K while still having flexibility over the mapping for individual peripherals, so this means not having multiple peripherals within one physical 64K region.
It's not just CoreSight, even the UARTs and other tiny peripherals are on 64K boundaries in Juno. I would expect quite a few SoCs are like that. The TRM is just saving space by not showing a 60K hole between them all.
