cmd: add a new command "config" to show .config contents

This feature is inspired by /proc/config.gz of Linux.  In Linux,
if CONFIG_IKCONFIG is enabled, the ".config" file contents are
embedded in the kernel image.  If CONFIG_IKCONFIG_PROC is also
enabled, the ".config" contents are exposed to /proc/config.gz.
Users can do "zcat /proc/config.gz" to check which config options
are enabled on the running kernel image.

The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled,
the ".config" contents are compressed and saved in the U-Boot image,
then printed by the new command "config".

The usage is quite simple.  Enable CONFIG_CMD_CONFIG, then run
 > config
from the command line interface.  The ".config" contents will be
printed on the console.

This feature increases the U-Boot image size by about 4KB (this is
mostly due to the gzip-compressed .config file).  By default, it is
enabled only for Sandbox because we do not care about the memory
footprint on it.  Of course, this feature is architecture agnostic,
so you can enable it on any board if the image size increase is
acceptable for you.

7 years agox86: qemu: Add a config for 64-bit U-Boot

x86: qemu: Add a config for 64-bit U-Boot

Add a new board config which uses 64-bit U-Boot. Supported features
are the same as the other 64-bit board (Google Chromebook Link).
It is a start for us to test 64-bit U-Boot easily without the need
to access a real hardware.

Note CONFIG_SPL_ENV_SUPPORT is required for QEMU 64-bit as without
this the SPL build fails at the end. This is just a workaround as
CONFIG_SPL_ENV_SUPPORT is not needed at all.

common/built-in.o:(.data.env_htab+0xc): undefined reference to 'env_flags_validate'
lib/built-in.o: In function `hsearch_r':
lib/hashtable.c:380: undefined reference to 'env_callback_init'
lib/hashtable.c:382: undefined reference to 'env_flags_init'
make[1]: *** [spl/u-boot-spl] Error 1

Except those SPL options required by 64-bit, compared to 32-bit
config, the following options are different:

- CONFIG_SYS_MALLOC_F_LEN has to be increased to 0x1000 for SPL.
- CONFIG_DEBUG_UART has to be included due to the weird issue.
  See TODO comments in arch/x86/cpu/x86_64/cpu.c:arch_setup_gd().
  Once this issue gets fixed, debug uart can be optional.

7 years agox86: Do relocation before clearing BSS

overwrite the start of the relocation area. This doesn't matter when running
from SPI flash, since it is read-only. But when relocating 64-bit U-Boot
