2009-04-04sh: sh7785lcr: Map whole PCI address space.Takashi Yoshii2-17/+8
PCI still doesn't work on sh7785lcr 29bit 256M map mode. 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. Tested on 7785lcr 29bit 128M map 7785lcr 29bit 256M map (NOT tested on 32bit) Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-04sh: Fix up DSP context save/restore.Michael Trimarchi7-137/+161
There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. 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.
