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.

arm: reset: Avoid a build error when the reset uclass is enabled

2015-09-03T03:28:23+00:00

There can be only one do_reset(). When CONFIG_RESET is enabled this is
provided by the reset uclass, and ARM's version should be disabled.

armv8: Add framework for CCN-504 interconnect configuration

2015-09-02T02:37:49+00:00

This patch adds a minimal framework for Dickens CCN-504
interconnect configuration - mainly related to adding Clusters/cores
to snoop/DVM domain and setting QoS of the RN-I ports.

LS2085A platform makes use of these configurations to support
better network data performance and to boot a SMP Linux.

common/cmd_boot: keep ARM v7M in thumb mode during do_go_exec()

2015-05-28T12:18:23+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.

arm: debug: add Kconfig entries for lowlevel debug

2014-10-26T21:23:12+00:00

We have not had a good method to debug the early boot stage such as
lowlevel_init function.  I guess developers generally use dedicated
debuggers for that, but it is difficult in some cases.
(For example, my debugger cannot connect to the ARM processor when
it is in the secure state.  It sometimes happens when I need to
debug the early boot stage on ARM SoCs with secure extension.)

The low level debug feature in Linux would be also helpful for U-boot
when we are stucking in nasty problems where the console is not
available yet.

You have to enable CONFIG_DEBUG_LL to use this feature.
For now, only 8250-compatible UART devices are supported.
You can add a header file under arch/arm/include/debug/ directory
to support your UART device if necessary.

arm: Add support for semihosting for armv8 fastmodel targets.

2014-07-03T06:35:45+00:00

The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.

Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.

Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.
