| ARM: set SCTRL[A] only when architecture does not support unaligned access
|
| Recent gcc generates code with unaligned access when architecture
| supports it. Setting A bit unconditionally causes data-aborts on such
| code rendering barebox unusable.

What the patch tried is correct: We should set the A bit only when the architecture
does not support unaligned accesses. To figure out whether the architecture supports
unaligned accesses the patch tested for the U bit which is wrong. The U bit may be
0 after a reset, so instead of testing for the U bit we have to set it. This can
be done on armv6 and later. All others have the A bit set to trap unaligned accesses.

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

In the commit 40492a0c13
(MIPS: add common header file for DEBUG_LL via NS16550)
introduced common DEBUG_LL via NS16550 for MIPS
(see file arch/mips/include/debug_ll_ns16550.h).
In the commit 1cbe2b2c00
(MIPS: XBurst: add Ritmix RZX-50 board support)
the file debug_ll_ns16550.h used in
the file arch/mips/mach-xburst/include/mach/debug_ll.h.
Usage looks like this:
------------------------------------------------
+#ifdef CONFIG_BOARD_RZX50
+#include <mach/debug_ll_jz4755.h>
+#endif
+
+#include <debug_ll_ns16550.h>
------------------------------------------------
So after adding another board (e.g. A320) we will have something like this:
------------------------------------------------
#ifdef CONFIG_BOARD_RZX50
#include <mach/debug_ll_jz4755.h>
#endif
+#ifdef CONFIG_BOARD_A320
+#include <mach/debug_ll_jz4740.h>
+#endif
#include <debug_ll_ns16550.h>
------------------------------------------------
This approach has disadvantage:
* the files mach/debug_ll_jz4740.h and mach/debug_ll_jz4755.h
(they go to arch/mips/arch-xburst) are __BOARD-SPECIFIC__
(not SOC- or mach-specific!); The file mach-xburst/include/mach/debug_ll.h
is outside board directory, but it contains some board related information.

Traditionally we call __mmu_cache_flush in early startup. There
is a problem with armv7 and hierarchical caches though, on these
systems __mmu_cache_flush uses the stack. Appearantly this was
seldomly a problem, because most of these systems have a ROM
bootloader which sets up some stack, but on a special i.MX6 system
this failed badly. We should not have to flush caches here. Every
sane system should pass control to the bootloader without stale
entries in the caches *), so it should be a safe assumption that the
cache flush can be removed.
Since __mmu_cache_flush is not called from early code anymore we can
also move it to the regular text section.
Be brave and give it a try.

We currently use the environment variable 'bootargs' to get the
Linux bootargs. This patch allows for a more flexible bootargs
generation using global variables. With it the Linux bootargs
are concatenated from multiple variables. This allows to replace
parts of the bootargs string without having to reconstruct it
completely.
With this bootargs can be constructed like:
global linux.bootargs.base="console=ttyS0,115200"
global linux.bootargs.ip="ip=dhcp"
global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)"
This will then automatically be combined into a kernel bootargs
string during boot.
If the 'linux.bootargs.' variables are all empty the old standard
'bootargs' way will be used.

arch/ppc/Kconfig is reworked to make the configuration environment
architecture neutral. All MPC5200 configuration is moved to the
MPC5200 architecture specific configuration file. These modifications
are reflected in the PCM030 board support.
arch/ppc/Makefile compilation directives are updated in preparation
for the introduction of future cpus/machines.
lib/time.c is moved to the architecture specific directory and the
building instructions updated in the Make files. The file is
cleaned up of unused code.
The definition of L1_CACHE_... is updated and CACHELINE_SIZE is
defined in ppc/include/asm/cache.h for future use by the mpc85xx.
The file mach-mpc5xxx/pci_mpc5200.c and mach-mpc5xxx/start.S are
updated accordingly.
The declaration of search_exception_table is moved in
include/asm/common.h because it is used across architectures.
mach-mpc5xxx/traps.c is also updated to reflect this change.
The definition of exception in asm/ppc_asm.tmpl is updated for future
use by the mpc85xx. The file starts.S in mach-mpc5xxx is updated
accordingly.

The imx51 lowlevel setup code currently sets the full cpu
speed only for TO3. It turned out that this is not a TO

the lowlevel init after babbage_power_init() so that we
can remove the hack from the generic i.MX51 lowlevel
function. As this potentially changes the UART clock we
have to flush the console beforehand and call the clock
notifier afterwards.

Traditionally U-Boot and barebox have the exception vectors at
the start of the binary. There is no real reason in doing so,
because in the majority of cases this data will not be at 0x0
where it could be used as vectors directly anyway.
This patch puts the vectors into a separate linker section and
defines an head function which is placed at the start of the
image instead. Putting this in a separate function also has
the advantage that it can be placed at the start of images
which require an additional header like several Freescale i.MX
images. As the head function contains the barebox arm magic
those images can now also be detected as barebox images.
