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

2017-08-16T12:30:24+00:00

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.

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

2017-06-30T01:18:48+00:00

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.

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

2017-06-10T00:34:54+00:00

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.

arm: Add declarations to avoid needing to include headers

2017-06-05T15:02:37+00:00

At present common.h includes various ARM-specific headers. In preparation
for dropping this, add a few explicit declarations.

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

2017-06-01T12:57:52+00:00

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

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

2017-04-27T20:49:08+00:00

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

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

2017-04-05T02:15:10+00:00

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

2017-01-18T17:29:33+00:00

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.

libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY

2016-12-03T03:54:34+00:00

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.
