On SH7785, PCI -> SHwy address translation is not base+offset but somewhat like base|offset (See HW Manual (rej09b0261) Fig. 13.11). So, you can't export CS2,3,4,5 by 256M at CS2 (results CS0,1,2,3 exported, I guess). There are two candidates. a) 128M@CS2 + 128M@CS4 b) 512M@CS0 Attached patch is B. It maps 512M Byte at 0 independently of memory size. It results CS0 to CS6 and perhaps some more being accessible from PCI.

| * | | | | sh: Fix up DSP context save/restore.Michael Trimarchi2009-04-047-137/+161

This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Forcing direct-mapped worked on certain older 2-way set associative parts, but was always error prone on 4-way parts. As these are the norm these days, there is not much point in continuing to support this mode. Most of the folks that used direct-mapped mode generally just wanted writethrough caching in the first place.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
