arm: asm/cache.c: Introduce arm_reserve_mmu

2020-04-24T19:17:14+00:00

As a preparation for turning reserve_mmu into an arch-specific variant,
introduce arm_reserve_mmu on ARM. It implements the default routine for
reserving memory for MMU TLB and needs to be weakly defined in order to allow
for machines to override it.

Without this decoupling, after introducing arch_reserve_mmu, there would be two
weak definitions for it, one in common/board_f.c and one in
arch/arm/lib/cache.c.

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

2018-05-07T13:34:12+00:00

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.

arm: Migrate SYS_THUMB_BUILD to Kconfig, introduce SPL_SYS_THUMB_BUILD

2017-03-19T00:28:01+00:00

Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for
various reasons.  We also have cases where we only build SPL in Thumb2 mode due
to size constraints and wish to build the rest of the system in ARM mode.  So
in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to
control if we build everything or just SPL (or in theory, just U-Boot) in
Thumb2 mode.

ARM: Move SYS_CACHELINE_SIZE over to Kconfig

2016-08-26T21:04:46+00:00

This series moves the CONFIG_SYS_CACHELINE_SIZE.  First, in nearly all
cases we are mirroring the values used by the Linux Kernel here.  Also,
so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux).  Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

arm: support Thumb-1 with CONFIG_SYS_THUMB_BUILD

2015-11-10T14:03:48+00:00

When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD,
some files fail to build, most of the time because they include
mcr instructions, which only exist for Thumb-2.

This patch introduces a Kconfig option CONFIG_THUMB2 and uses
it to select between Thumb-2 and ARM mode for the aforementioned
files.
