sh: Support PCI IO access of SH7780 base boards.

2007-11-30T03:36:13+00:00

The IO access of PCI is not supported in R7780RP and the MS7780SE
board now. The support of the IO access mode of e100 and a lot of IDE
chips becomes possible by fixing the code.

sh: fix R2D-1 CF support

2007-11-23T05:39:13+00:00

This patch fixes CF support for R2D-1 boards. Both R2D-1 and
R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version
seem to deliver IRQ spikes with certain CF cards during libata
probing.  This patch enables polling for R2D-1 as a workaround
for this broken FGPA logic.

R2D-1 CF support was recently introduced by commit:
43f4b8c7578b928892b6f01d374346ae14e5eb70.

sh: lockless UTLB miss fast-path.

2007-11-19T04:05:18+00:00

With the refactored update_mmu_cache() introduced in older kernels,
there's no longer any need to take the page_table_lock in this path,
so simply drop it completely.

Without this, performance degradation is seen on SMP on heavily
threaded workloads that don't use the split ptlock, and ultimately
we have no reason to contend for the lock in the first place.

sh: Kill off UTLB flush in fast-path.

2007-11-19T04:00:32+00:00

The __do_page_fault() fast-path contains a UTLB flush in order to
force an ITLB reload, this isn't needed in practice as the ITLB is
auto-reloaded from the UTLB anyways, which is already displaced by
the manual 'ldtlb' in the update_mmu_cache() path.

This provides a measurable speed up in the TLB miss fast-path.

sh: Kill off broken snapgear ds1302 code.

2007-11-08T02:24:33+00:00

This will force the snapgear boards to use the on-chip SH RTC instead,
until the rtc-ds1302 driver is merged. The current code is broken
and hasn't built in some time, so just kill it off and get the board
working again.
