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: fix compile warnings when semihosting is enabled on ARMv7M target.

2015-11-10T08:45:36+00:00

This patch fixes compile warnings like this:

warning: format '%lu' expects argument of type 'long unsigned int',
         but argument 5 has type 'size_t'

In C99 standard you can use %zu modifier to print size_t values.

arm: add support for semihosting for ARMv7M targets

2015-11-10T08:45:33+00:00

If you enable CONFIG_SEMIHOSTING for STM32F429 target, you will get compile
error looking like this:

arch/arm/lib/semihosting.c: In function 'smh_read':
{standard input}: Assembler messages:
{standard input}:34: Error: invalid swi expression
{standard input}:34: Error: value of 1193046 too large for field of 2 bytes at 0
scripts/Makefile.build:277: recipe for target 'arch/arm/lib/semihosting.o' failed

The source of the problem is "svc #0x123456" instruction. This instruction
can not be encoded using Thumb2 instruction set used by ARMv7M CPUs.
ARM documentation suggests using "bkpt #0xAB" instruction instead [1].
This patch fixes compile errors and adds support for semihosting for
STM32F429 or any other ARMv7M target.
This change was sested on STM32F429-DISCOVERY board using OpenOCD and
"smhload" u-boot command.

arm: Switch 32-bit ARM to using generic global_data setup

2015-10-24T17:50:36+00:00

There is quite a bit of assembler code that can be removed if we use the
generic global_data setup. Less arch-specific code makes it easier to add
new features and maintain the start-up code.

Drop the unneeded code and adjust the hooks in board_f.c to cope.

armv8/gic: Fix GIC v2 initialization

2015-10-15T12:47:03+00:00

Initialize all GICD_IGROUPRn registers and set up GICC_CTLR to enable
interrupts to the primary CPU. This fixes issues seen after booting a
Linux kernel from U-Boot.
