Fixed the prom_relocate() function in start.S file by reserving memory in
the board_init_f sequence and saving the offset to the __prom_start_reloc
variable. This value is used as the destination when relocating the PROM.

Add the prom_init() function to the end of the board_init_r sequence.

Introduce the CONFIG_SYS_TIMER_* macros in include/asm/config.h to make use
of the generic timer infrastructure in lib/time.c.

Created a timer_init() function to initialize the timer hardware and update
the #ifdef in board_init_f to allow this function to be called during the
start-up sequence.

Reworked the LEON2 start.S code to call board_init_f function at startup.
Also implemented the relocate_code function in assembly to relocate the

Add the CONFIG_SYS_GENERIC_BOARD variable to all the LEON2 boards.

Now that u-boot relocates the malloc area in SPL to SDRAM, with the
malloc area sitting below the SPL_STACK_R_ADDR the
SPL_STACK_R_MALLOC_SIMPLE_LEN needs to be set explicitly for
rockchip as its SPL_STACK_R_ADDR (512kb) is smaller then
STACK_R_MALLOC_SIMPLE_LEN (1Mb).

Using the same value as SYS_MALLOC_F_LEN (8kb) is enough to load u-boot
from SD card.

This patch was merged shortly before the v2015.10 as a minimal fix for
booting on rockchip. Now that the patch series from Hans to do the
relocation in generic code has been merged it can be dropped.

This reverts commit b1f492ca.

Commit 1eb0c03c added
SPL_SYS_MALLOC_SIMPLE Kconfig option and changed the way it is
evaluated.

Thus, the definitions of CONFIG_SYS_MALLOC_SIMPLE in rk3***_common.h
board configs are now incorrect because CONFIG_SPL_BUILD is enabled so
CONFIG_IS_ENABLED(SYS_MALLOC_SIMPLE) will look for SPL_SYS_MALLOC_SIMPLE
instead of SYS_MALLOC_SIMPLE.

This commit fix this enabling SPL_SYS_MALLOC_SIMPLE with the new Kconfig
option by default in rockchip-mach.
