* [MTD] chips cfi_cmdset_0002: Prevent timeout raceKonstantin Baidarov2005-11-071-9/+9
| | | | | | | | | | | | | | | | | | We've noticed that sometimes "MTD do_write_buffer(): software timeout" message was printed out when writing to a Fujitsu NOR flash. It turned out that this was because of a race in the timeout handling do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and sometimes if the timer interrupt handling takes more than one or even two jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just after chip_ready() call, the driver bails out from a ready polling loop despite the chip has actually become ready while all those interrupts were handled. To deal with this issue, extra check for chip ready is neccessary on timeout expiration (and the checks should better be reordered). As do_write_oneword() uses the same approach, it needs to also be changed.

* [MTD] maps/plat-ram: Avoid gcc 4.0 warningThomas Gleixner2005-11-071-2/+2
| | | | | | | | | The assignement of a "const char *" to a "char *" variable is emitting a warning with gcc 4.0. We cannot change mtd->name to "const char *" as we have dynamic assignements of the name. So casting is the correct solution here Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* [MTD] NAND: nand_write_ecc memory and OOB corruptionTodd Poynor2005-11-071-0/+1
| | | | | | | | | | Nathan Roberts noticed the nand_write_ecc index into oobbuf goes out of bounds when crossing an erase block boundary, causing incorrect OOB data to be written and corrupting memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Nvidia Geforce 7800 series of cards to the nvidiafb framebuffer driver. All it does is add the PCI device id for the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work on these cards. I also added the relevant PCI device ids to linux/pci_ids.h I tested it on my 7800 GTX here and it works like a charm. I now can get framebuffer support on this card! Woo hoo!!
