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
