[U-Boot] [PATCH v2 0/9] make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN

[Andy Yan]

Some platforms like RK3036 has very small sram to run spl code, so
it has no enough sapce for so much malloc pool before relocation in
spl stage as the normal u-boot stake.
As the long discussion in [1] [2], I make this series out, try to
make spl and normal u-boot stage use independent SYS_MALLOC_F_LEN.

Changes in v2:
- introduce a new control CONFIG_SPL_SYS_MALLOC_F_LEN, adviced by Simon
- set spl pre relocation malloc pool by CONFIG_SPL_SYS_MALLOC_F_LEN

Andy Yan (9):
  make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN
  mips: spl and normal u-boot stage set SYS_MALLOC_F indepently
  powerpc: spl and normal u-boot stage set SYS_MALLOC_F indepently
  microblaze: spl and normal u-boot stage set SYS_MALLOC_F indepently
  rockchip: set malloc pool size to 0 before relocation in spl state on
    rk3036 based board
  rockchip: disable SPL_ARCH_MEMCPY/MEMSET for rk3036
  rockchip: enable SPL_LIBGENERIC for rk3036 based boards
  rockchip: use debug() instead of printf when back to bootrom
  rockchip: add u-boot specific dts for rk3036 sdk
