* 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.

As sender and receiver are not in sync it's impossible to transfer a packet successfully. So when we get a NAK send '\xff' bytes until the receiver reaches the packet boundary. When we send too many the SoC replies with a NAK for each byte and doesn't interpret it as the start of a new package (which must start with SOH == '\x01'). A slower alternative would be to wait for another NAK which is sent when reception of the already started packet times out. This was tested on an Armada XP based machine with bootrom version 1.20.
