still doesn't work.

with global early_serial_base got :

early console in setup code
[    0.000000] bootconsole [uart0] enabled


with static early_serial_base got :

early console in setup code
early console in decompress_kernel
decompress_kernel:
  input: [0x24a0269-0x2e8b234], output: 0x1000000, heap: [0x2e909c0-0x2e979bf]

Decompressing Linux... Parsing ELF... done.
Booting the kernel.
[    0.000000] bootconsole [uart0] enabled


Thanks

Yinghai
