Geert,
see the following patch series for the hopefully final word on
the 'make ST-RAM pool accessible for kernels running from FastRAM'
story.
ST-RAM pool is allocated from an arch initcall if the kernel runs
in FastRAM, at which time memory mapping support is up and running
and ioremap works as it should.
This should make current kernels run again on TTs with insufficent
ST-RAM but enough TT-RAM to hold the kernel and user data. It does
speed up kernel operations a great deal on Falcon hardware with
FastRAM on accelerators.
Side effects: rebooting from a kernel in FastRAM will go through a
hard reboot -no idea why. SCSI operations seem to fail sooner than
otherwise on my system (the SCSI patches are not in my atafb-stram
branch). Need to investigate on both accounts.
Please review and apply.
Cheers,
Michael
