fs: fix tracking of initial position with O_APPEND (*) 
(*) O_APPEND is *not* functional yet, this is just a hack for write-only
streams. Currently O_APPEND does not reposition the cursor at the end of
the file before every write.

fs: buffer Fugue writes through RAM 
Writing from ROM causes occasional crashes, which are fairly hard to
produce when the buffers are small.

ld: reserve stack space from the static RAM region 2022-01-10 14:47:14 +01:00

fs: use a static variable in calls to BFile_Create() 
There is no evidence that BFile_Create() keeps the address and writes
to it later on, but I'd rather be overly careful than have to debug a
stack corruption problem in half a year :)

dma: do not use ICS in foreign unbinds 
I'm pretty sure it makes no difference because the OS does not rely on
interrupts for most (if not all) of its DMA operations, but it's better
to keep it clean anyway.

dma: remove IE flag at end of transfer 
This should have no effect since the channel is disabled, but it's much
better to leave unused modules in predictable states.

fs: track offset of Fugue files manually 
This helped locate some bugs:
* read() could read past EOF due to BFile_Read() allowing you to read up
  until the end of the last sector, beyond the file size
* pread() did not restore the file offset because the negative seek at
  the end is not relative (that was the CASIOWIN fs API), so pread()
  could not actually be written without knowing the current position
* lseek() would clamp you to EOF but still return its out-of-bounds
  arguments, as a direct result of BFile_Seek() doing that

Benefits:
* Made pread() a generic function

kernel: tentative stack overflow panic, 14 kiB stack on G-III 
I saw a crash with the 12 kB stack. Added an error message to diagnose
further similar issues, and bumbed the stack to 14 kB. That's a lot of
space just for BFile but stability is queen... :x

hardware: expose filesystem type in the hardware info 
Filesystem type is detected with a trivial heuristic:
* fx-9860G: CASIOWIN, unless Fugue in the G-III series (OS >= 3.00)
* fx-CG 50: Always Fugue

kernel: increase stack size to 12 kB on SH4 fx-9860G 
BFile calls on the G-III series can overflow an 8 kB stack, overriding
the VBR which is located just before (!).

tmu: fix freeze when using sleep_us_spin() with interrupts on

dma: add support for standard DMA access to SPU memory 
* Mark SPU memory as sleep-blocking.
* Perform 4-byte accesses only in dma_memset() and dma_memcpy() (32-byte
  accesses freeze as one would expect).

This change does *NOT* implement support for SPU's integrated DMAC.
