libfdt: move headers to and

2018-03-05T15:16:28Z

Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include -> #include #include -> #include Reported-by: Thomas Petazzoni Signed-off-by: Masahiro Yamada

ARM: bootm: don't assume sp is in DRAM bank 0

2018-01-12T17:12:31Z

arch_lmb_reserve() currently assumes that the stack pointer is within DRAM bank 0. This is not necessarily true. Enhance the code to search through DRAM banks until the bank that does contain SP is found, and then reserve the tail of that bank.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24Z

We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also. Suggested-by: Wolfgang Denk Signed-off-by: Simon Glass

Revert "armv7m: Disable D-cache when booting nommu(ARMv7M) Linux kernel"

2017-06-30T01:18:48Z

The author of the commit discovered later on that this was already being done in cleanup_before_linux() on arch/arm/cpu/armv7m/cpu.c. This reverts commit 8f079cccb369995e46a2ab530d5d60b88c1e70bb. Signed-off-by: Tom Rini

armv7m: Disable D-cache when booting nommu(ARMv7M) Linux kernel

2017-06-10T00:34:54Z

Disable D-Cache is required when booting nommu Linux kernel. (please see Linux kernel source "arch/arm/kernel/head-nommu.S") U-Boot is enabled D-cache and I-Cache at startup. However, it does not disable D-Cache before booting nommu Linux kernel. Therefore, I call dcache_disable() when the CPU is ARMv7M to fix this problem. Signed-off-by: Toshifumi NISHINAGA

arm: Add declarations to avoid needing to include headers

2017-06-05T15:02:37Z

At present common.h includes various ARM-specific headers. In preparation for dropping this, add a few explicit declarations. Signed-off-by: Simon Glass

dm: Use dm.h header when driver mode is used

2017-06-01T12:57:52Z

This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass

arm/lib/bootm.c: keep ARM v7M in thumb mode during boot_jump_linux()

2017-04-27T20:49:08Z

On ARM v7M, the processor will return to ARM mode when executing a blx instruction with bit 0 of the address == 0. Always set it to 1 to stay in thumb mode. Tested on STM32f746-disco board Similar commit: f99993c10882f7dc8ec35993d5febe59aac01e6a Author: Matt Porter Signed-off-by: Patrice Chotard

arm: bootm: Add dm_remove_devices_flags() call to announce_and_cleanup()

2017-04-05T02:15:10Z

This patch adds a call to dm_remove_devices_flags() to 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.

armv8: aarch64: Fix the warning about x1-x3 nonzero issue

2017-01-18T17:29:33Z

For 64-bit kernel, there is a warning about x1-x3 nonzero in violation of boot protocol. To fix this issue, input argument 4 is added for armv8_switch_to_el2 and armv8_switch_to_el1. The input argument 4 will be set to the right value, such as zero. Signed-off-by: Alison Wang Reviewed-by: Alexander Graf Tested-by: Ryan Harkin Tested-by: Michal Simek Reviewed-by: York Sun
