* linux_compat: handle __GFP_ZERO in kmalloc()Masahiro Yamada2015-07-22-7/+6
| | | | | | | | | | | | | | | | | Currently, kzalloc() returns zero-filled memory, while kmalloc() simply ignores the second argument and never fills the memory area with zeros. I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does, which will make it easier to add more memory allocator variants. With the introduction of __GFP_ZERO flag, going forward, kzmalloc() variants can fall back to kmalloc() enabling the __GFP_ZERO flag.

* fdt: Add a function to remove unused strings from a device treeSimon Glass2015-07-21-0/+32
| | | | | | | | | | | | Property names are stored in a string table. When a node property is removed, the string table is not updated since other nodes may have a property with the same name. Thus it is possible for the string table to build up a number of unused strings. Add a function to remove these. This works by building a new device tree from the old one, adding strings one by one as needed. Signed-off-by: Simon Glass <sjg@chromium.org>

* libfdt: fix error code of fdt_count_strings()Masahiro Yamada2015-07-20-1/+1
| | | | | | | | | | | | | Currently, this function returns a positive value on error, so we never know whether this function has succeeded or failed. For example, if the given property is not found, fdt_getprop() returns -FDT_ERR_NOTFOUND, and then this function inverts it, i.e., returns FDT_ERR_NOTFOUND (=1).

* | blackfin: fix undefined reference to srand and randMasahiro Yamada2015-06-11-1/+3
|/ | | | | | | | | | | | | | | | | | | | | Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies) accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards. Prior to that commit, those boards defined CONFIG_LIB_RAND, but not CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have touched them, but in fact it ripped CONFIG_LIB_RAND off from all the header files, which caused undefined reference to srand and rand. CONFIG_LIB_RAND=y must be revived for such boards. BTW, this commit indeed makes it better, but even with this fix, three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not build due to region 'ram' overflowed error. This was cause by commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs) because CMD_NET selects NET, and NET selects REGEX. Eventually, some boards were newly enabled with CONFIG_REGEX, increasing the memory footprint. A patch is expected to fix the build error.

* x86: Refactor PIRQ routing supportBin Meng2015-06-04-0/+1

It has several PIRQ links (normally 8) and corresponding registers (either in PCI configuration space or memory-mapped IBASE) to configure the legacy 8259 IRQ vector mapping.

| | | | | | | | | | | | | | | | After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi builds would no longer boot. The problem is that stdout-path is now set like this in the upstream dts files: stdout-path = "serial0:115200n8". The use of options in of-paths, either after an alias name, or after a full path, e.g. stdout-path = "/soc@01c00000/serial@01c28000:115200", is standard of usage, but something which the u-boot dts code so far did not handle.
