This patch adds a new "page" parameter to all NAND read_page/read_page_raw
APIs. The read_page API for the new mode ECC_HW_OOB_FIRST requires the
page information to send the READOOB command and read the OOB area before
the data area.

Remove the ARM dependency from the generic "onenand" platform device
driver. This change makes the driver useful for other architectures as
well. Needed for the SuperH kfr2r09 board.
Apart from the obvious Kconfig bits, the most important change is the move
away from ARM specific includes and platform data. Together with this
change the only in-tree board code gets an update, and the driver name is
also changed gracefully break potential out of tree drivers.
The driver is also updated to allow NULL as platform data together with a
few changes to make use of resource_size() and dev_name().

orion_nand_probe lives in .init.text, so using platform_driver_register to
register it is wrong because binding a device after the init memory is
discarded (e.g. via sysfs) results in an oops.
As requested by Nicolas Pitre platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially. This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.

Commit log for commit 517d3cc15b
("[libata] ata_piix: Enable parallel scan") says:
This patch turns on parallel scanning for the ata_piix driver.
This driver is used on most netbooks (no AHCI for cheap storage it seems).
The scan is the dominating time factor in the kernel boot for these
devices; with this flag it gets cut in half for the device I used
for testing (eeepc).
Alan took a look at the driver source and concluded that it ought to be safe
to do for this driver. Alan has also checked with the hardware team.
and it is all true but once we put all things together additional
constraints for PATA controllers show up (some hardware registers
have per-host not per-port atomicity) and we risk misprogramming
the controller.
I used the following test to check whether the issue is real:
@@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_
(timings[pio][1] << 8);
}
pci_write_config_word(dev, master_port, master_data);
- if (is_slave)
+ if (is_slave) {
+ if (ap->port_no == 0) {
+ u8 tmp = slave_data;
+
+ while (slave_data == tmp) {
+ pci_read_config_byte(dev, slave_port, &tmp);
+ msleep(50);
+ }
+
+ dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan "
+ "race detected\n");
+ }
pci_write_config_byte(dev, slave_port, slave_data);
+ }
/* Ensure the UDMA bit is off - it will be turned back on if
UDMA is selected */
and it indeed triggered the error message.
Lets fix all such races by adding an extra locking to ->set_piomode
and ->set_dmamode methods for PATA controllers.
[ Alan: would be better to take the host lock in libata-core for these
cases so that we fix all the adapters in one swoop. "Looks fine as a
temproary quickfix tho" ]
