[U-Boot] [PATCH v2] microblaze: Disabling interrupt should return 1 if was enabled

[于会]

Dear Wolfgang Denk,
 
    I'm Abraham Yu, here is my first time write to you, I feel so happy to join the U-Boot team.
 
I was porting arm926ejs SoC to our new SoC call "AVT2210", OK! Here is some basically questions below:
(u-boot.1010.12.rc2 is what I am using.)
 
1). First, I am useing JTAG to download image to SDRAM, base address 0x40000000, (32M) so I confused with
     "CONFIG_SYS_TEXT_BASE", I think this this the relocate address, I am right? Could you please help
     me choose a address for me can working. (I choose 0x41F00000, at last crash on relocate: copy_loop)
 
2). Second, CONFIG_SYS_INIT_SP_ADDR address is also obscure, I choose 0x42000000, at last crash on relocate: copy_loop)
 
3). What other thing I should do?
 
Thanks very much, God bless you.
 
Abraham
