Realization of no printing information for Linux terminal

Linux starts with a lot of information to print, to make the boot information do not print, you need to modify the kernel in two places:

1. Kernel configuration items.

Config_serial_atmel_console=y//Remove terminal configuration options.
2. When the kernel decompression, the terminal due to uboot initialization, so the decompression information will be printed, comment out the kernel decompression printing.

Arch/arm/boot/compressed/misc.c

//putstr ("uncompressing Linux ...");
231 do_decompress (Input_data, Input_data_end-input_data,
232 output_data, error);
233//putstr ("done, booting the kernel.\n");
