* spl: make image arg or fdt blob address reconfigurableVikas Manocha2017-05-081-3/+3
| | | | | | | | | | | At present fdt blob or argument address being passed to kernel is fixed at compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from different media like nand, nor flash are copied to the address pointed by the macro. The problem is, it makes args/fdt blob compulsory to copy which is not required in cases like for NOR Flash. This patch removes this limitation. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>

* libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORYMasahiro Yamada2016-12-021-0/+5
| | | | | | | | | | | | | | | | | | Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt(). It will be useful when we want to use a memory node from a kernel DTB as is, but need some fixups for Spin-Table/PSCI.

* Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada2016-09-231-1/+0
| | | | | | | | | | | | | | Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. Actually, U-Boot does not export headers to user-space, so we just have to care about the consistency in the U-Boot tree. Now all of include directives for <asm/errno.h> are gone.

* Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass2016-03-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

| | | | | | | | | | | | | | | | | 'extern inline' is not portable across various C standards. To ensure compatiblity with various standards/compilers change the functions to static inline. This is a portable construct and serves as a comparable definition to 'extern inline' from the gnu90 standard. Additionally remove the function prototypes as they are not required due to the functions being declared static and functions are correctly ordered based on dependence.
