This adds required header files for the sandbox architecture, and a basic description of what sandbox is (README.sandbox).

Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v2: - Removed unneeded clock.h - Moved gpio.h to asm-generic, removed GPIO_COUNT - Removed kernel cruft from posix_types.h - Removed dummy field from struct pt_regs - Remove contents of string.h; instead include linux/string.h - Remove unneeded functions in u-boot-sandbox.h - Remove contents of unaligned.h; instead include asm-generic/unaligned.h

These files are taken from the ARM board implementation and then reduced to remove unneeded cruft.

Ideally we would work towards unifying arch/xxx/lib files, particularly board.c.

Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v2: - Fix commit message typo, sadly - Remove ARM cruft from Makefile - Remove version_string and make display_banner() call display_options() - Tidy up DRAM logic (but I think it is still needed to fit in with U-Boot) - Remove use of CONFIG_SYS_NO_FLASH - Make board_init_f() call board_init_r() for now - Make board_init_r() call main_loop() for now

By default sections are 16-byte aligned on some architectures, but the command name structure (struct cmd_tbl_s) does not have padding to 16 bytes. This change reduces the alignment to 4-bytes so that the command table can be accessed correctly on any architecture.

(Note: this needs doing properly)
