In OpenSPARC T1+ TWINX ASIs in store instructions are aliased
with Block Initializing Store ASIs.
"UltraSPARC T1 Supplement Draft D2.1, 14 May 2007" describes them
in the chapter "5.9 Block Initializing Store ASIs"
Integer stores of all sizes are allowed with these ASIs.

Please note that QEMU doesn't impelement Real->Physical address
translation. The "Real Address" is always the "Physical Address".

Accordinf to UA2005, 9.3.3 "Address Space Identifiers",
"In hyperprivileged mode, all instruction fetches and loads and stores with implicit
ASIs use a physical address, regardless of the value of TL".

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
