sf: fix timebase data type in _wait_ready()

2016-04-25T19:10:30+00:00

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

2016-04-22T09:47:37+00:00

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.

stm32: stm32_flash: add memory barrier during flash write

2016-04-12T00:48:23+00:00

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.

kirkwood_nand: claim MPP pins on the fly

2016-04-06T13:40:33+00:00

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.
