* spl: fix linker size check off-by-one errorsSimon Goldschmidt2019-05-051-1/+1
| | | | | | | | | This fixes SPL linker script size checks for 3 lds files where the size checks were implemented as "x < YYY_MAX_SIZE". Fix the size checks to be "x <= YYY_MAX_SIZE" instead. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>
* arch: types.h: factor out fixed width typedefs to int-ll64.hMasahiro Yamada2018-09-101-31/+2
| | | | | | | | | | | | | All architectures have the same definition for s8/16/32/64 and u8/16/32/64. Factor out the duplicated code into <asm-generic/int-ll64.h>. BTW, Linux unified the kernel space definition into int-ll64.h a few years ago as you see in Linux commit 0c79a8e29b5f ("asm/types.h: Remove include/asm-generic/int-l64.h").

* configs: Migrate CONFIG_NR_DRAM_BANKSTom Rini2018-08-161-2/+0

| | | | | | | | | | | CMD_DM is used for debug purpose and it shouldn't be enabled by default via Kconfig.

* microblaze: Convert generic platform to DM gpioMichal Simek2018-07-193-13/+9
| | | | | | | | | | | | | | | | | | | | | | | | Converting GPIO to DM requires to do changes in reset subsystem that's why support for Microblaze soft reset via sysreset and GPIO sysreset support was added. These two patches enables enabling GPIO DM. Microblaze soft reset is bind at last reset method. GPIO reset is handled via sysreset with adding this fragment to DT. gpio-restart { compatible = "gpio-restart"; gpios = <&reset_gpio 0 0 0>; /* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */ }; hard-reset-gpio property is not documented and also handled. Conversion is required. Unfortunately do_reset is required for SPL that's why use only soft microblaze reset for now. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

| | | | | | | | | | Timer needs to be converted to DM but as of now it can't be called so early because intc controller is not ready. Call it later in board_r.c. Before this patch timer_init is called twice which is wrong. The patch is blocking initialization before relocation.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0726-56/+26
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

* fdt: Implement weak arch_fixup_fdt()Alexey Brodkin2018-02-181-5/+0
| | | | | | | | | | | | | | | | | | | Only ARM and in some configs MIPS really implement arch_fixup_fdt(). Others just use the same boilerplate which is not good by itself, but what's worse if we try to build with disabled CONFIG_CMD_BOOTM and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was apparently implemented in arch/xxx/lib/bootm.c. Now with weak arch_fixup_fdt() right in image-fdt.c where it is used we get both items highlighted above fixed.

* spl: add hierarchical defaults for SPL_LDSCRIPTPhilipp Tomsich2017-08-131-0/+3
| | | | | | | | | | | | | | | | With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config node), all the lingering definitions in header files will cause warnings/errors due to the redefinition of the configuration item. As we don't want to pollute the defconfig files (and values should usually be identical for entire architectures), the defaults are moved into Kconfig. Kconfig will always pick the first default that matches, so please keep these values at the end of each file (to allow any board-specific Kconfig, which will be included earlier) to override with an unconditional default setting.

| | | | | | | | | | | | | | | | | | 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.

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.
