* mtd: nand: nand_mxs: Fix readtotal calculationChristian Hemp2016-11-111-4/+4
| | | | | | | | | | | | | | | | | | | | | The calculation of readtotal must be bit alligend. If not the bch core finds bit flips in every page, because readtotal is too small. This bug was mostly introduced since commit "51061a9 mtd: nand: nand_mxs: Add subpage read support". Tested with: nand: NAND device: Manufacturer ID: 0x01, Chip ID: 0xd3 (AMD/Spansion S34ML08G2), 1024MiB, page size: 2048, OOB size: 128 nand: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micron MT29F4G08ABADAWP), 512MiB, page size: 2048, OOB size: 64 nand: NAND device: Manufacturer ID: 0xec, Chip ID: 0xd3 (Samsung NAND 1GiB 3,3V 8-bit), 1024MiB, page size: 2048, OOB size: 64 Signed-off-by: Christian Hemp <c.hemp@phytec.de> Signed-off-by: Stefan Lengfeld <s.lengfeld@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: Make UBI detection more robustSascha Hauer2016-11-111-11/+24
| | | | | | | | | | | | | When we want to detect if a mtd device contains an UBI image then testing the first block is not enough since it can always happen that UBI has just erased the block before the power failed during last boot. Since UBI only ever erases one block at a time and directly writes the ec header to it afterwards, it shouldn't be necessary to scan the whole device for UBI data. Scan the first 64 blocks. The first non-empty block then must contain UBI data, if instead we find foreign data we assume that no UBI is on that mtd device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* nand: imx6: Changed default NAND clockDaniel Schultz2016-11-111-1/+1
| | | | | | | | | | | | | | | The Barebox recognized false bad erase blocks while booting from a Spansion NAND (1). This error occurred due a to high clock. The Kernel sets the default NAND clock to 22Mhz. So, to fix this error and to be more identical with the Kernel, the Barebox should be too. 1: nand: NAND device: Manufacturer ID: 0x01, Chip ID: 0xd3 (AMD/Spansion S34ML08G2), 1024MiB, page size: 2048, OOB size: 128 Signed-off-by: Daniel Schultz <d.schultz@phytec.de> Tested-by: Stefan Lengfeld <s.lengfeld@phytec.de> Signed-off-by: Christian Hemp <c.hemp@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mtd: ubi: enable thread earlierSascha Hauer2016-10-191-9/+5
| | | | | | | | | | | Since "57cebc4 mtd: ubi: Fix scrubbing during attach" we make sure that the wear level worker does not start too early. However, now there are cases when the worker starts too late. When a ubi image is freshly written a volume may be autoresized. This has to be done after the wear level worker is started because otherwise the initial fastmap update will not be able to find any anchor PEBs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: bootm: Fix free_mem calculation when initrd is givenSascha Hauer2016-10-181-1/+1
| | | | | | | | | | | | | | When a initrd is given we calculate the next free memory position as: free_mem = PAGE_ALIGN(initrd_end); This is wrong when initrd_end exactly falls on a page boundary. In this case PAGE_ALIGN() does nothing and free_mem becomes initrd_end and the following bootm_load_devicetree() and thus booting fails with -ENOMEM. Fix this by correctly advancing to the next free memory position. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mtd: ubi: Fix scrubbing during attachSascha Hauer2016-10-113-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | ensure_wear_leveling() is called at the end of ubi_wl_init() and may come to the decision to scrub some blocks. In the Kernel this is done in a separate thread, but in barebox we do this synchronously. The problem is that during ubi_wl_init() the EBA system is not yet initialized (ubi_eba_init() is not yet called), so the wear level worker hits a NULL pointer deref when the fastmap needs to be updated and ubi_write_fastmap() accesses vol->eba_tbl. Solve this by honoring the ubi->thread_enabled flag which is only set to true when UBI is sufficiently initialized. This means we now can have multiple works queued, so we can no longer simply do one work when queued, but instead have to continue to do work until all work is done. The best place to do so is a ubi_thread() function which behaves similar to the Kernel function with the same name, but is called synchronously in barebox. To make sure that the initially queued works are done, the call to (no-op) wake_up_process() at the end of ubi_attach_mtd_dev() is replaced with a call to ubi_thread(). While at it also honor the ubi->ro_mode flag to make sure we do not do any wear leveling work on readonly UBI devices. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | The i.MX6 USB phy does not recognize disconnects of high speed devices when the USBPHY_CTRL_ENHOSTDISCONDETECT is not set. The phy does not work properly though when this bit is always set, so implement the notify_(dis)concect() callbacks to set this bit whenever a high speed device is connected and to clear it again when the device is disconnected.
