Sascha Hauer 20e9bc17d4 ARM: Create an assembly arm_cpu_lowlevel_init function
To avoid the code duplication between the static inline C
function and the assembly macro.

Jean-Christophe PLAGNIOL-VILLARD c49819d903 arm: rename reset and common_reset to barebox_arm_reset_vector and arm_cpu_lowlevel_init
reset is confusing with the cpu reset and impossible to grep

Sascha Hauer 94c06f9447 ARM Samsung boards: switch to barebox_arm_entry
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.

Jan Luebbe faf7b7af6e ARM: give boards control of the reset entry point
On some SoCs (for example AM35xx), the ROM bootloader passes useful
information in r0 when jumping to barebox.

To avoid overwriting this in the generic reset code, we introduce
common_reset as a C function and as an assembler macro. This is then
called form the reset entry point (either in common or in board code).

This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

Juergen Beisert 59994faae6 MACH SAMSUNG/S3C: Re-work the memory detection and handling
Keep common code in the MACH instead of re-inventing it in each platform.
Also use S3C* macros for all memory related register.

Jean-Christophe PLAGNIOL-VILLARD d8c86961b3 move boards to arch/<architecure>/boards
this will allow each arch to handle the boards more simply and depending on
there need

the env var BOARD will refer to the current board dirent

for sandbox as we have only one board the board dirent is arch/sandbox/board
