Log:
aic79xx.c:
Include read streaming in the PPR flags we display in diagnostics.
In ahd_reset(), set the known mode after our initial pause prior to
setting the mode. We can't just set the mode directly because the
current mode, after the pause, is most likely unknown and setting the
mode when the saved mode is unknown will trigger an assertion in
the mode debug code.
Complete an audit for SCB RAM reads. These reads must be performed
via the special ahd_in?_scbram() methods so we can perform a
Rev A. PCI-X workaround.
Remove a superfluous mode save operation that was performed just
prior to a call to ahd_clear_critical_section(). The saved mode
was never restored and wouldn't have been valid anyway since the
mode could change while single stepping out of a critical section.
aic79xx.h:
Add new BUG definition AHD_PCIX_SCBRAM_RD_BUG.
aic79xx_inline.h:
Update ahd_inb_scbram routine to check for AHD_PCIX_SCBRAM_RD_BUG
and only apply the workaround if this bug is active. The old code
applied the workaround in all cases.
aic79xx_pci.c:
Set AHD_PCIX_SCBRAM_RD_BUG for the A4.
Remove an attempted saved_modes call in ahd_pci_test_register_access().
Saving the modes can only occur when we are paused, but the call was
happening before the chip was known to be paused. Restoring the
modes doesn't make sense either since the code makes no assumptions
about the state of the sequencer until the first time the mode is set
by the driver. This happens after the registers are successfully
mapped.
