HAVE_CONFIGURABLE_MEMORY_LAYOUT was first meant as a feature, now it's a
feature to remove it. barebox on ARM now completely uses the memory passed
in from the lowlevel code and configures the malloc area and stack space
during runtime making it obsolete to hardcode these values.

This architecture is a bit strange. It has up to four SDRAM banks, but
all have a quite limited size. The SDRAM size for the different boards
currently is unknown as it's configurable with Kconfig. We use a SDRAM
size based on the value of the only board we have in the defconfigs:
edb9301. This likely breaks other ep93xx boards.

All Samsung boards automatically detect their SDRAM size. The size detection
code can't be called safely from lowlevel C code, so instead the minimum SDRAM
size is guessed from the defconfig files.

All boards use hardcoded SDRAM addresses, copied from the board init file.
OMAP3 boards are a bit special, they had a SoC specific reset() function. This
is renamed to omap3_invalidate_dcache() and called from the board lowlevel init
code now.

Most i.MX boards can use the imx*_barebox_entry functions. The remaining
(i.MX21, i.MX6) use hardcoded base addresses.

Hi Sascha,
I've made the changes you suggested in this resent patch.
Everything related to custom ATAGs has been moved to the board
directory.
The generic code does not make any references to feature lists or
bootloader versions.
About the setup_feature_list prototype:
it has been renamed to atag_appender
it's not a function, it's a pointer to a function. Can it have a
prototype other than it's own declaration?
All non-related changes has been dropped. They were checkpatch.pl
warnings unrelated to this patch.
Regards,
Vicente.

This patch provides a global cleanup barebox Kconfig files. This includes
replacing spaces to tabs, formatting in accordance format, removing
extraneous lines and spaces. No functional changes.

This adds lowlevel debug functions for i.MX. As we have a great variety
of different UARTs on i.MX currently no Kconfig support for chosing the
correct one is added. Instead we expect the user to add the correct
define and issue a compiler warning if he hasn't.

This patch adds new architecture (CLPS711X) into barebox.
The core-logic functionality of the device is built around an ARM720T
processor running at clock speeds up to 90 MHz.

This was once disabled because we had no board support. This has
changed, so enable the S5P board support in the config so that
the friendlyarm_tiny210_defconfig actually builds for the correct
machine.

This allows for creating a pre-bootloader binary for
- nand boot
- mmc boot
- compressed image
The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.
Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and
implement a dummy panic.
For now on introduce dummy zbarebox* targets and c code that will contain later
the decompressor. This only implemeted on ARM.
