| * state: backend_raw: properly align write and erase sizeMarc Kleine-Budde2015-05-261-7/+7
| | | | | | | | | | | | | | | | | | | | This patch makes it easier to share the code with linux, on Linux the ease and write size have to be aligned. Use stride (which is already aligned to erase block size) during erase, align size_full to writesize and use it while writing.

| * state: backend_raw: remove hard coded limit of two copiesMarc Kleine-Budde2015-05-261-5/+12
| | | | | | | | | | | | | | | | | | Although there is the define RAW_BACKEND_COPIES, the state_backend_raw_save() function silently assumes exactly two copies. This patch removes that assumtion by looping over all copies, but saving the one we're read from at the end.

| * state: add fixup to copy state from barebox to kernel device treeMarc Kleine-Budde2015-05-261-7/+100
| | | | | | | | | | | | | | | | This patch registers a DT fixup, that copies the state nodes from the active to the kernel DT. The backend reference will be a phandles. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * state: backend: support phandle and of_path referencesMarc Kleine-Budde2015-05-151-3/+6
| | | | | | | | | | | | | | | | | | | | | | This patch improves the backend property, it can be either a phandle or a of_path. During probe() of the state driver the backend property is dereferenced and the resulting of_path is saved in the state context. In a later patch it will be used to generate a phandle reference to the backend during DT fixup.

| | | | | | | | | | | | | | | | | | | | This patch adds the functionality to export the description of the state, but not the contents of the variables to a DT node. This will be used in a later patch to "copy" the state description to the kernel device tree during DT fixup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 64bit architectures TLSF_64BIT should be defined. Decide that depending on the CONFIG_64BIT symbol. When 64bit support is enabled all allocations will be aligned to 8 byte boundaries which is necessary for architectures that do not support unaligned accesses or have a performance penalty for unaligned accesses. Also changes the undefined tlsf_decl to 'static'. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | Using xfunctions to allocate log messages is not a good idea. Should we be out of memory the xfunctions will panic which will cause another allocation, so we deadlock the system with no message going out. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original mem_test() was rather long an contained code to perform two distinct operations.

| * | common/memtest.c: Do not omit offset of 0 from testsAndrey Smirnov2015-05-151-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ommiting offset 0 from address line tests allows certain corner cases of faults to be undetected. For the "stuck high" case, consider scenario in which all of the tested address lines are stuck high. In original code first data filling loop would execute writing data to a single cell multiple times and second loop would just read data from that cell over and over again. Adding a write to start[0] should prevent this since it would cause the second loop to read incorrect data on its first iteration. For the "stuck low" case, having any of the tested bits of the address shorted would effectively "remap" that memory cell to start[0] in this case excluding start[0] during the verification phase would result in a false positive result. Note that both of the changes are present in Michael Barr's code here: http://www.esacademy.com/en/library/technical-articles-and-documents/miscellaneous/software-based-memory-testing.html and the code in barebox is based on that code.
