Move #ifdef(CONFIG_DISPLAY_CPUINFO) from caller to callee

2014-02-19T16:10:05+00:00

- When CONFIG_DISPLAY_CPUINFO is not enabled,
   print_cpuinfo() should be defined as an empty function
   in a header, include/common.h

 - Remove #ifdef CONFIG_DISPLAY_CPUINFO .. #endif
   from caller, common/board_f.c and arch/arm/lib/board.c

 - Remove redundant prototypes in arch/arm/lib/board.c,
   arch/arm/include/asm/arch-am33x/sys_proto.h and
   board/nokia/rx51/rx51.h, keeping the one in include/common.h

 - Add #ifdef CONFIG_DISPLAY_CPUINFO to the func definition
   where it is missing

dts: re-write dts/Makefile more simply with Kbuild

2014-02-19T16:10:05+00:00

Useful rules in scripts/Makefile.lib allows us to easily
generate a device tree blob and wrap it in assembly code.

We do not need to parse a linker script to get output format and arch.

This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb.

Commit 643aae1406c93ddc64fcf8c136b47cdffd9c8ccd
deleted include/linux/config.h but missed to
delete _LINUX_CONFIG_H macro.
It is no longer used at all.

common/cmd_bootm: extend do_bootm_vxworks to support the new VxWorks boot interface.

2013-12-16T13:59:05+00:00

The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware
description mechanism. For PowerPC, the boot interface conforms to
the ePAPR standard, which is:

   void (*kernel_entry)(ulong fdt_addr,
          ulong r4 /* 0 */,
          ulong r5 /* 0 */,
          ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */,
          ulong r8 /* 0 */, ulong r9 /* 0 */)

For ARM, the boot interface is:

   void (*kernel_entry)(void *fdt_addr)

sandbox: Make map_to_sysmem() use a constant pointer

2013-11-21T23:54:26+00:00

Very often a constant pointer is passed to this function, so we should
declare this, since map_to_sysmem() does not change the pointer.

exynos: Export timer_get_us() to get microsecond timer

2013-10-08T12:48:10+00:00

This function, if implemented by the board, provides a microsecond
timer. The granularity may be larger than 1us if hardware does not
support this.

ARM: add SMP support for non-secure switch

2013-10-03T19:28:51+00:00

Currently the non-secure switch is only done for the boot processor.
To enable full SMP support, we have to switch all secondary cores
into non-secure state also.

So we add an entry point for secondary CPUs coming out of low-power
state and make sure we put them into WFI again after having switched
to non-secure state.
For this we acknowledge and EOI the wake-up IPI, then go into WFI.
Once being kicked out of it later, we sanity check that the start
address has actually been changed (since another attempt to switch
to non-secure would block the core) and jump to the new address.

The actual CPU kick is done by sending an inter-processor interrupt
via the GIC to all CPU interfaces except the requesting processor.
The secondary cores will then setup their respective GIC CPU
interface.
While this approach is pretty universal across several ARMv7 boards,
we make this function weak in case someone needs to tweak this for
a specific board.

The way of setting the secondary's start address is board specific,
but mostly different only in the actual SMP pen address, so we also
provide a weak default implementation and just depend on the proper
address to be set in the config file.
