hello,all
          i want to place my kernel loadaddr=0x81008000 and set EBASE=0x81000000, it workes.
         but there is still some memory usable before 0x81000000, for example from 0x80100000 ~ 0x80200000
         i have try to pass param as mem=1M@1M mem=16M@16M  to the kernel,  it seems only take the 0x8000000 ~ kernel_end as reserved.
         is there any other options to set the memory useable? ( my kernel version is 2.6.14)
         thanks for any hints
