Hello, Jeff.
This patchset implements ata_wait_register() and uses it in ahci and
sata_sil24. The function is generalized form of ahci_poll_register()
with the following differences.
* Uses ioread32.
* The first read is done before calculating timeout such that
unflushed io write doesn't affect timeout. (no flush required
before calling this function.)
* Test conditions is negated. As it waits for something to change,
negated test is more natural/powerful and allows this function to be
used for wider purpos.
* Returns the last read value of @reg.
This patchset contains five patches.
#01-02 fix & prep sata_sil24 for following changes
