2014-12-08fdt: Allow non-FDT kernels to boot when CONFIG_OF_LIBFDT is definedSuriyan Ramasami
The boot commands - bootz/bootm mandate a third argument which is the address to the FDT blob. In cases where this argument is not specified, boot fails with a message indicating a missing FDT. This causes non-FDT kernels to fail to boot. This patch allows both FDT and non-FDT kernels to boot by making the third parameter to the bootm/bootz optional.

2014-12-08Fix console functions for U-Boot APISimon Glass
Commit 709ea54 made a subtle change to the way the U-Boot API jump table is set up. So at present putc(), getc(), tstc() and puts() do not work correctly from functions that use the U-Boot API. Previously these were set to the stdio functions, but these now take a parameter specifying which stdio device to use. Instead, we should change them to use the global functions which do not have a parameter. This is a slight change in behaviour. The functions will now output to all selected stdio devices - for example putc() will output a character to all devices selected by stdout. However in most cases there is only one, and it isn't necessarily incorrect behaviour anyway. The API version is not changed since it is compatible with what was there before.

2014-11-23hush: add CONFIG_HUSH_PARSER to KconfigMasahiro Yamada
The README file states that the macros beginning with "CONFIG_SYS_" depend on the hardware etc. and should not be meddled with if you do not what you're doing. We have already screwed up with this policy; we have given the prefix "CONFIG_SYS_" to many user-selectable configurations. Here, "CONFIG_SYS_HUSH_PARSER" is one of them. Users can enable it if they want to use a more powerful command line parser, or disable it if they only need a simple one. This commit attempts to rename CONFIG_SYS_HUSH_PARSER to CONFIG_HUSH_PARSER and move it to Kconfig. Every board maintainer is expected to enable CONFIG_HUSH_PARSER (= add "CONFIG_HUSH_PARSER=y" to his defconfig file) and remove "#define CONFIG_SYS_HUSH_PARSER" from his header file.

2014-11-21dm: Split the simple malloc() implementation into its own fileSimon Glass
The simple malloc() implementation is used when memory is tight. It provides a simple buffer with an incrementing pointer. At present the implementation is inside dlmalloc. Move it into its own file so that it is easier to find. Rather than using relocation as a signal that the full malloc() is available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the simple malloc() should no longer be used. In some cases, such as SPL, even the code space used by the full malloc() is wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple malloc. In this case the full malloc is not available at all. It saves about 1KB of code space and about 0.5KB of data on Thumb 2.
