2015-08-28lib/display_options: Fix print_freqSuriyan Ramasami
Build without CONFIG_SPL_SERIAL_SUPPORT does not print the cpu freq. I have seen this in the odroid U3 board, where on boot one sees this: CPU: Exynos4412 @ GHz instead of: CPU: Exynos4412 @ 1 GHz I am assuming that this change was done to get rid of compiler warnings related to unused variables when building with CONFIG_SPL_SERIAL_SUPPORT not being defined in an SPL build.

2015-08-18of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

2015-08-18of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROLMasahiro Yamada
As we discussed a couple of times, negative CONFIG options make our life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ... and here is another one. Now, there are three boards enabling OF_CONTROL on SPL: - socfpga_arria5_defconfig - socfpga_cyclone5_defconfig - socfpga_socrates_defconfig This commit adds CONFIG_SPL_OF_CONTROL for them and deletes CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert the logic.

2015-08-14Revert "fdt: Fix fdtdec_get_addr_size() for 64-bit"Simon Glass
This reverts commit 5b34436035fc862b5e8d0d2c3eab74ba36f1a7f4. This function has a few problems. It calls fdt_parent_offset() which as mentioned in code review is very slow. https://patchwork.ozlabs.org/patch/499482/ https://patchwork.ozlabs.org/patch/452604/ It also happens to break SPI flash on Minnowboard max which is how I noticed that this was applied. I can send a patch to tidy that up, but in any case I think we should consider a revert until the function is better implemented. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-08-05efi: Add support for loading U-Boot through an EFI stubSimon Glass
It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.

2015-07-22linux_compat: handle __GFP_ZERO in kmalloc()Masahiro Yamada
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.

2015-07-21fdt: Add a function to remove unused strings from a device treeSimon Glass
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.

2015-06-11blackfin: fix undefined reference to srand and randMasahiro Yamada
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.
