[U-Boot] [PATCH 2/2] blackfin: Do not generate unused binary init.elf

[Zhang, Sonic]

Hi Yamada,

The init.elf is used to debug u-boot boot process on Blackfin via JTAG. You can't load u-boot binary to memory via JTAG without run the init.elf in Blackfin L1 SRAM first. So, this can't be removed.

Regards,

Sonic
