* arm: mach-omap: Change file flags in emmc handlerDaniel Schultz2017-05-051-1/+1
| | | | | | | | | This handler tries to read from a file descriptor with 'write only' flags and fails. Add read permissions for the file, so the handler can read the partition layout. Signed-off-by: Daniel Schultz <d.schultz@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* globalvar: don't use nv_device if CONFIG_NVVAR is disabledAntony Pavlov2017-04-251-1/+11
| | | | | | | | | | | | | | | | | | | At the moment barebox crashes if CONFIG_NVVAR is disabled because of access to unregistered nv_device in get_param_by_name(&nv_device, "version"). How to reproduce the crash: barebox$ unset ARCH barebox$ unset CROSS_COMPILE barebox$ make sandbox_defconfig barebox$ sed -i "s/CONFIG_ENV_HANDLING=y/# CONFIG_ENV_HANDLING is not set/" .config barebox$ make oldconfig barebox$ ./barebox Segmentation fault Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* state: backend_raw: init digest earlierSascha Hauer2017-04-241-4/+6
| | | | | | | | | In backend_format_raw_pack() digest_length is used before it's initialized in backend_raw_digest_init() which results in a too small memory allocation for the raw backend. Fix this and prevent a memory corruption. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* state: Fix "pack" returning freed data for DTB backendIan Abbott2017-04-211-2/+0
| | | | | | | | | | | | | | | | `state_backend_format_dtb_pack()` passes a buffer containing state packed in flattened DTB format back to its caller via its `buf` parameter. It then frees the buffer before returning. This means the caller (`state_save()`) will be working on freed buffer contents before freeing the buffer a second time itself. Fix it by removing the spurious call to `free()`. This should fix a bug reported by Norbert Wiedmann in <http://lists.infradead.org/pipermail/barebox/2017-April/029980.html>.

* ARM: cache-l2x0: honour aux_val when determing way sizeSascha Hauer2017-04-211-4/+3
| | | | | | | | | | | | | | l2x0_init() allows to overwrite bits in the AUX_CTRL register using the aux_val/aux_mask arguments. On i.MX35 this is used to pass a correct AUX_CTRL value to overwrite bogus reset values for this register. To make this work we have to apply aux_val/aux_mask before using the AUX_CTRL value to determine the way size. This fixes: 3f7e890da7 ARM: l2x0: Implement L310 support Before this commit the way size was hardcoded to 8. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | Set needs_refresh back to 0 after refreshing so that we do not refresh it again without need. This would only happen when we read the state from the storage multiple times, which normally is not the case. However, it's more consistent like this.

* mtd: nand_omap_gpmc: fix BCH error correctionMatt Reimer2017-04-191-1/+2
| | | | | | | | | | | | | | | | | | | BCH error detection and correction was only looking at the first of four syndrome polynomials, which meant it was failing to detect and correct bitflips in the last 3/4 of the data. In effect, only the first 512 bytes of a 2048 byte page were being protected by ECC. The syndrome polynomials (BCH error codes) are stored in the NAND's OOB, each of which protects 512 bytes of data. The driver used eccsteps = 1 which effectively made it only use the first polynomial, and therefore was only protecting the first 512 bytes of the page. The fix is to pull over a bit of code from the kernel's omap_correct_data() that sets eccsteps = 4 when the page size is 2048 bytes and hardware ECC is being used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The device node path may change from the internal device tree to the one Linux is started with, so using this path to fixup the tree is not very robust.

| * | state: Remove -EUCLEAN check from userspace toolSascha Hauer2017-03-311-21/+0

This patch only introduces a change for the userspace tool, not for barebox. In Linux userspace there is no direct possibility to check for -EUCLEAN. To indirectly check for -EUCLEAN the state tool reads the number of corrected bits before and after reading a block. Unfortunately it does not take the number of acceptable bitflips into account, but instead returns -EUCLEAN even when only a single bitflip occurred on a whole page. To be correct the algorithm must be more complicated: We would have to read the bitflip_threshold from sysfs. This value is per ECC step (often 512 byte), not per page. We would have to read the page in ECC step size chunks, testing for bitflips lower than the threshold for each chunk. Even if we would do that, there's still another issue. The eccstats ioctl delivers the eccstats for the whole device, so a concurrent reader would falsify the result. Let's decide that this is not worth the hassle and assume that no device has enough uptime that a cleanup in barebox is not sufficient. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
