* fix erasing/protecting flashes with unspecified sizeSascha Hauer2016-04-198-8/+12
| | | | | | | | | | | | | | | | | fixes: 81737c1 mtd: Fix erasing of devices >4GiB Several places erased a complete flash partition passing ~0 as count to erase(). With the above commit count to erase was changed from an unsigned type to a signed type, so the (count > f->size - offset) check in erase() no longer triggers and the ~0 count is no longer adjusted to the whole device size. Among other things this results in saveenv failures on NOR flashes. This patch fixes this by introducing an explicit macro for erasing the whole device which is tested for in erase(). All other negative values are rejected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Giorgio <giorgio.nicole@arcor.de>
* i2c_probe: fix wrong start and stop addressesMiquel Raynal2016-04-151-1/+1
| | | | | | | | | | This patch fixes the wrong range of i2c addresses used by the i2c_probe command when a stop address is provided. In this case the start address (startaddr) was taking the value of the stop address and the stop address (stopaddr) was always set to its default value.

| | | | | | | | | | Displaying an unsigned 64-bit integer can be represented by up to 20 characters. The 20 bytes buffer reserved to store the formatted string "%llu Bytes" is to small: (20 + 6) = 26. Hence, a bigger buffer is reserved to hold this string.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | raw read/write was not possible because we enabled the ECC engine during driver initialization. To support raw mode we have to disable the ECC engine dynamically when needed. This has to be done before the send_page function is called. The places where we have to disable the ECC engine are not available in the driver, but are buried in the Nand layer. To make them available we have to implement driver specific write/read_page functions in which we configure the ECC mode. This also makes the driver better readable as it makes the detour around the driver internal data buffer when reading/writing pages unnecessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

For 2k pages the controller reads and corrects in chunks of 512 bytes. The ECC status register values are overwritten with each each new chunk read, so after reading for chunks the .correct callback wil only return the ECC errors for the last 512 byte chunk. ECC errors in the other three chunks remain undetected. Fix this by accumulating the ECC status while reading the chunks and return the accumulated value in the .correct callback. Also return -EBADMSG for a bad message and not -1. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
