The license text is copied to the top of each file as is done with other bzip2 files in U-Boot. The only other change is to squash a compiler warning with nBytes.

Its intented to be used in U-Boot SPL versions on platforms with very limited internal RAM sizes. To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig.

Add an option to tell U-Boot that the device tree should be placed at the end of the image binary (_image_binary_end) instead of at the end of BSS.

* fdtdec: fix parsing 'reg' property with zero value in '#size-cells'Przemyslaw Marczak2015-10-03-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After rework of lib/fdtdec.c by: commit: 02464e3 fdt: add new fdt address parsing functions the function fdtdec_get_addr() doesn't work as previous, because the implementation assumes that properties '#address-cells' and '#size-cells' are equal to 1, which can be not true sometimes. The new API introduced fdtdec_get_addr_size_auto_parent() for the 'reg' property parsing, but the implementation assumes, that #size-cells can't be less than 1. This causes that the following children's 'reg' property can't be reached: parent@0x0 { #address-cells = <1>; #size-cells = <0>; children@0x100 { reg = < 0x100 >; }; }; Change the condition value from '1' to '0', which allows parsing property with at least zero #size-cells, fixes the issue. Now, fdtdec_get_addr_size_auto_parent() works properly. Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).

* fdt: fix fdtdec_get_addr_size not to require any size cellsStephen Warren2015-10-03-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fdtdec_get_addr_size() may be used in two cases: a) With sizep supplied, in which case both an address and a size are parsed from DT. In this case, the DT property must be large enough to contain both values. b) With sizep NULL, in which case only an address is parsed from DT. In this case, the DT property only need be large enough to contain this address value. Commit 02464e386bb5 "fdt: add new fdt address parsing functions" broke this relaxed checking, and required the DT property to contain both an address and a size value in all cases. Fix fdtdec_get_addr_size() to vary ns based on whether the size value is being parsed from the DT or not. This is safe since the function only parses the first entry in the property, so the overall value of (na + ns) need not be accurate, since it is never used to step through the property data to find other entries. Besides, this fixed behaviour essentially matches the original behaviour before the patch this patch fixes. (The original code validated that the property was exactly the length of either na or (na + ns), whereas the current code only validates that the property is at least that long. For non-failure cases, the two behaviours are identical).

This is incorrect in many cases depending on the DT binding for a particular node or property (e.g. it is incorrect for the "reg" property). In most cases, DT parsing code must use the properties #address-cells and #size-cells to parse addres properties. This change splits up the implementation of fdtdec_get_addr_size() so that the core logic can be used for both hard-coded and non-hard-coded cases. Various wrapper functions are implemented that support cases where hard-coded cell counts should or should not be used, and where the client does and doesn't know the parent node ID that contains the properties #address-cells and #size-cells. dev_get_addr() is updated to use the new functions. Core functionality in fdtdec_get_addr_size_fixed() is widely tested via fdtdec_get_addr_size(). I tested fdtdec_get_addr_size_auto_noparent() and dev_get_addr() by manually modifying the Tegra I2C driver to invoke them. Much of the core implementation of fdtdec_get_addr_size_fixed(), fdtdec_get_addr_size_auto_parent(), and fdtdec_get_addr_size_auto_noparent() comes from Thierry Reding's previous commit "fdt: Fix fdtdec_get_addr_size() for 64-bit".

* | env: import: hashtable: Prevent buffer overrun when importing environment ↵Lukasz Majewski2015-09-15-2/+3
|/ | | | | | | | | | | | | | | | | | | | | from file Lets consider following scenario: - One uses echo -n "key=value" to define environment variable in a file (single variable) - The file content is "key=value" without any terminating byte (e.g. 0x0a or 0x0d). - The file is loaded to u-boot non zero'ed RAM buffer (with load command). - Then "env import -t -r $loadaddr $filesize" is executed. - Due to lack of proper termination byte we have classical example of buffer overrun. This patch prevents from this by allocating one extra byte than size and explicitly null terminate it. There should be no change for normal env import operation after applying this patch.

* Move malloc_cache_aligned() to its own headerSimon Glass2015-09-11-1/+4
| | | | | | | | | | | | | | | | | | | At present malloc.h is included everywhere since it recently was added to common.h in this commit: 4519668 mtd/nand/ubi: assortment of alignment fixes This seems wasteful and unnecessary. We have been trying to trim down common.h and put separate functions into separate header files and that change goes in the opposite direction. Move malloc_cache_aligned() to a new header so that this can be avoided. The header would perhaps be better named as alignmem.h but it needs to be included after common.h and people might be confused by this. With the name memalign.h it fits nicely after malloc() in most cases. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
