sf: fix timebase data type in _wait_ready()

2016-04-25T19:10:30Z

get_timer() returns an unsigned 64-bit value, but is currently assigned to a signed 32-bit variable. Due to sign extension and data truncation, this causes the timeout loop in spi_flash_cmd_wait_ready() to immediately (and incorrectly) fire for about 50% of all time values, based on whether bit 31 is set. In sandbox at least, this causes the test to pass or fail based on system uptime, as opposed to time since the U-Boot binary was started.

mtd, ubi: set free_count to zero before walking through erase list

2016-04-22T09:47:37Z

Set free_count to zero before walking through ai->erase list in wl_init(). As U-Boot has no workqueue/threads, it immediately calls erase_worker(), which increase for each erased block free_count. Without this patch, free_count gets after this initialized to zero in wl_init(), so the free_count variable always has the maybe wrong value 0. Detected this behaviour on the dxr2 board, where the UBI fastmap gets not written when attaching/dettaching on an empty NAND. It drops instead the error message: could not find any anchor PEB With this patch, fastmap gets written on dettach. Signed-off-by: Heiko Schocher Reviewed-by: Boris Brezillon

stm32: stm32_flash: add memory barrier during flash write

2016-04-12T00:48:23Z

After writing data to flash space, next instruction is checking if flash controller is busy writing to the flash memory. Memory barrier is required here to avoid transaction re-ordering for data write and busy status check. Signed-off-by: Vikas Manocha

kirkwood_nand: claim MPP pins on the fly

2016-04-06T13:40:33Z

Claim the MPP pins for the NAND flash controller only when it's actually being used. This allows the pins to be shared with the SPI interface which already supports an equivalent on-access MPP reconfiguration.
