Define board_quiesce_devices() in a shared location

2018-06-03T13:27:21Z

This undocumented function relies on arch-specific code to declare a nop weak version. Add the weak function in common code instead to avoid having to duplicate the same function in each arch. Signed-off-by: Simon Glass Signed-off-by: Alexander Graf

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

fdt: Implement weak arch_fixup_fdt()

2018-02-18T19:53:38Z

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.

Revert "x86: bootm: Fix FIT image booting on x86"

2017-11-30T05:50:17Z

This reverts commit 13c531e52a09b4e6ffa8b5a1457199b0a574cb27. The error message with FIT style image mentioned in the above commit only happens when booting using FIT image containing bzImage kernel and without setup node (setup.bin). The current documentation for x86 FIT support in doc/uImage.FIT/x86-fit-boot.txt mentions that kernel's setup.bin file is required for building x86 FIT images. The above commit breaks FIT images generated as described in the documentation. Revert it to allow booting with images built in the documented way.

x86: bootm: Add dm_remove_devices_flags() call to bootm_announce_and_cleanup()

2017-05-17T09:13:06Z

This patch adds a call to dm_remove_devices_flags() to bootm_announce_and_cleanup() so that drivers that have one of the removal flags set (e.g. DM_FLAG_ACTIVE_DMA_REMOVE) in their driver struct, may do some last-stage cleanup before the OS is started.

x86: bootm: Fix FIT image booting on x86

2017-04-10T02:02:03Z

Checking 'is_zimage' at this time will always fail and therefore booting a FIT style image will always lead to this error message: "## Kernel loading failed (missing x86 kernel setup) ..." This change now removes this check and booting of FIT images works just fine. Signed-off-by: Stefan Roese Cc: Simon Glass Cc: Bin Meng Reviewed-by: Simon Glass Reviewed-by: Bin Meng

x86: Don't build call64 and setjmp on 64-bit

2017-02-06T03:38:46Z

These are currently not supported. Calling 64-bit code from 64-bit U-Boot is much simpler, so this code is not needed. setjmp() is not yet implemented for 64-bit. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY

2016-12-03T03:54:34Z

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.

ls2080: Exit dpaa only right before exiting U-Boot

2016-11-17T13:18:55Z

On ls2080 we have a separate network fabric component which we need to shut down before we enter Linux (or any other OS). Along with that also comes configuration of the fabric using a description file. Today we always stop and configure the fabric in the boot script and (again) exit it on device tree generation. This works ok for the normal booti case, but with bootefi the payload we're running may still want to access the network. So let's add a new fsl_mc command that defers configuration and stopping the hardware to when we actually exit U-Boot, so that we can still use the fabric from an EFI payload. For existing boot scripts, nothing should change with this patch. Signed-off-by: Alexander Graf Reviewed-by: York Sun [agraf: Fix x86 build]

x86: Call board_final_cleanup() in last_stage_init()

2016-05-23T07:18:00Z

At present board_final_cleanup() is called before booting a Linux kernel. This actually needs to be done before booting anything, like SeaBIOS, VxWorks or Windows. Move the call to last_stage_init() instead. Signed-off-by: Bin Meng Reviewed-by: Simon Glass
