env: import: hashtable: Prevent buffer overrun when importing environment from file

2015-09-15T19:05:08+00:00

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.

fdt: add new fdt address parsing functions

2015-09-15T13:57:13+00:00

fdtdec_get_addr_size() hard-codes the number of cells used to represent
an address or size in DT. 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".

Move malloc_cache_aligned() to its own header

2015-09-11T21:15:16+00:00

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.

mmc: dw_mmc: Probe the MMC from OF

2015-09-04T09:54:20+00:00

Rework the driver to probe the MMC controller from Device Tree
and make it mandatory. There is no longer support for probing
from the ancient qts-generated header files.

This patch now also removes previous temporary workaround.
