looks like that change to microblaze dts is wrong.

Michal, it seems lmb in microblaze have lmb special?

in arch/microblaze/

include/asm/cpuinfo.h:  u32 use_dlmb;
include/asm/cpuinfo.h:  u32 use_ilmb;
kernel/cpu/cpuinfo-pvr-full.c:  CI(use_dlmb, D_LMB);
kernel/cpu/cpuinfo-pvr-full.c:  CI(use_ilmb, I_LMB);
kernel/cpu/cpuinfo-static.c:    ci->use_dlmb = fcpu(cpu, "xlnx,d-lmb");
kernel/cpu/cpuinfo-static.c:    ci->use_ilmb = fcpu(cpu, "xlnx,i-lmb");
kernel/prom.c:#include <linux/lmb.h>
kernel/prom.c:  lmb_add(base, size);
kernel/prom.c:  return lmb_alloc(size, align);
kernel/prom.c:  lmb_init();
kernel/prom.c:  lmb_analyze();
kernel/prom.c:  pr_debug("Phys. mem: %lx\n", (unsigned long) lmb_phys_mem_size());
mm/init.c:#include <linux/lmb.h>
mm/init.c:      for (i = 0; i < lmb.memory.cnt; i++) {
mm/init.c:              memory_start = (u32) lmb.memory.region[i].base;
mm/init.c:              memory_end = (u32) lmb.memory.region[i].base
mm/init.c:                              + (u32) lmb.memory.region[i].size;
mm/init.c:      lmb_reserve(kernel_align_start, kernel_align_size);
mm/init.c:      lmb_reserve(PFN_UP(TOPHYS((u32)klimit)) << PAGE_SHIFT, map_size);
mm/init.c:      for (i = 0; i < lmb.reserved.cnt; i++) {
mm/init.c:                      (u32) lmb.reserved.region[i].base,
mm/init.c:                      (u32) lmb_size_bytes(&lmb.reserved, i));
mm/init.c:              reserve_bootmem(lmb.reserved.region[i].base,
mm/init.c:                      lmb_size_bytes(&lmb.reserved, i) - 1, BOOTMEM_DEFAULT);
mm/init.c:                      lmb.memory.region[0].size = memory_size;
mm/init.c:      if (!lmb.reserved.cnt) {
mm/init.c:      if ((u32) lmb.memory.region[0].size < 0x1000000) {
mm/init.c:      memory_start = (u32) lmb.memory.region[0].base;
mm/init.c:      memory_end = (u32) lmb.memory.region[0].base +
mm/init.c:                              (u32) lmb.memory.region[0].size;
mm/init.c:      lmb_reserve(kstart, ksize);
mm/init.c:              p = __va(lmb_alloc_base(PAGE_SIZE, PAGE_SIZE,
platform/generic/system.dts:                    xlnx,d-lmb = <0x1>;
platform/generic/system.dts:                    xlnx,i-lmb = <0x1>;

thought we should keep d-lmb and i-lmb, and change other lmb to memblock.

Thanks
